3 Neo-Dyn Repeatability, Accuracy and Maintenance for ressure Switches REEATABILITY Repeatability is the maximum set point deviation of a single pressure switch under one given set of environmental and operational conditions. Since adjustable pressure switches can be set at any discrete set point within its given adjustable range this is the most common performance criteria stated by the manufacturer. A general repeatability statement is that a ITT Neo-Dyn pressure switch will repeat within ± 0.5% of its set point when set in the upper 80% of its adjustable range for set points above 10 psig. Exceptions to this statement could include piston sensor pressure switches and switches whose adjustable range is inches of water. ACCURACY Accuracy is a term generally associated with analog instruments such as transducers and transmitters. Since a pressure switch is meant to give a contact opening or closure at a discrete set point an accuracy statement can only be given if all operational and environmental conditions are clearly defined. For example, what is the accuracy of an Neo-Dyn model 10012C3 when set at 150 psig increasing pressure when cycled between 150 psig and 130 psig for 500 cycles over a temperature range of +40 to +160 degrees Fahrenheit at a cycle rate of 15 cycles per minute. Again, the model, the operational and environmental conditions must all be defined. ITT Neo-Dyn can provide limited testing on some of its models under various test conditions. MAINTENANCE Under normal circumstances ITT Neo-Dyn pressure switches do not require maintenance or re-calibration. For critical applications or those where the switches are used in a severe environment, it is suggested a calibration check be performed at intervals based upon actual in service stability data.

4 Neo-Dyn Temperature Limitations for ressure Switches ressure switch applications often have media temperatures that are in excess of our published specifications. Even though most of Neo-Dyn s switches can actually withstand temperatures higher than those listed, they are published for varying reasons that include effects on; set point shift, decreased life expectancy, or in some cases, damage. O-rings themselves have limitations even though they are capable of temperatures higher than those we publish for the switches. Generally speaking, Buna-N and ER are good up to 250 F (121ºC), Viton up to 400 F (204ºC). The welded assemblies have no o-rings at all. The main purpose of this bulletin is to advise the end user that the media temperature limitations of these switches can be overcome by simply increasing the distance of the switch from the source of the media. Since Neo-Dyn s pressure switches are dead-ended devices, the temperature at the diaphragm or piston will not be the same as it is at the media. Often a 1 ft. (30.46 cm) length of uninsulated 1/4 inch, SS tubing is enough to lower the temperature to within published specifications. The rule of thumb utilized for these applications is as follows: For every 2 ft. (60.96 centimeters) of uninsulated-1/4 inch-ss tubing, you dissipate 100 ºF (37.77 ºC), in excess of +200 ºF (+93.3 ºC). It will of course depend on the initial media temperature, type of media, ambient temperature, and piping size & material. In some cases a longer capillary may be the best solution. Typically the tubing is coiled, so as to conserve space (pig tail). There are also other methods for dissipating heat, such as condensate chambers or reservoirs filled with liquid, which will act in the same manner as a diaphragm seal in isolating and dissipating the heat. These methods are better explained in ISA, ASME or other such industry and engineering standard practice texts.

7 Neo-Dyn Conventional ressure Switch Design Constant Rate Spring A constant rate type pressure switch, i.e., a bellows, diaphragm, bourdon tube and spring loaded piston, are linear devices for a certain pressure change the pressure element moves a given distance. For additional movement more pressure (force) is applied. The position of the electrical switch, therefore, influences and/or dictates the pressure switch set point. DIAHRAGM SRING LOADED ISTON BELLOWS BOURDON TUBE Disadvantages of the Constant Rate Switches NON-STABLE SET OINTS - Requires Constant Recalibration BECAUSE: Sensor mechanism follows the system pressure subject to fatigue. Set point influenced by snap acting electrical variations in snap switch differential affects deadband of pressure switch. Ambient temperature sensitive relocation of electrical switch causes change in set points. Linkage used to adjust electrical switch linkage wear relocates electrical, causing set point change. VIBRATION SENSITIVE - Causes Contact Chatter BECAUSE: Constant rate device mimics dynamic input intermittent electrical signal if vibration occurs when switch is near actuation. Larger mass associated with constant rate sensor mechanisms more mass means less vibration resistance. Spring mounted electricals or linkages resonance frequency can cause spring or linkage to take off causing electrical contacts to chatter. OVER-RESSURE SENSITIVE - Affects Set oint Accuracy BECAUSE: Motion transfer device must contain pressure bellows, bourdon tubes, and welded diaphragms contain pressure as well as actuate the electrical. Limited sensor support sensors with limited overpressure support are subject to set point drift. LIMITED CYCLE LIFE - Dependent on Set oint BECAUSE: Longer stroke repositioning the electrical for set point changes requires greater movement. Shorter electrical life sneaking up on the electrical can cause an electrical arc.

8 Neo-Dyn ressure Switch Design Nega-Rate Belleville Spring A negative rate type pressure switch (i.e., a Belleville spring) is a snap acting device. At a certain pressure (apex of the spring curve) the spring snaps over center. At this point, it takes less pressure (force) to continue its movement. The pressure switch set point is a function of the Belleville spring. The electrical switch is in a fixed position and is synchronized to the movement of the Belleville. DEACTUATED Advantages of the Nega-Rate Belleville Disc Spring Switches STABLE SET OINTS - Eliminates Constant Recalibration BECAUSE: No moving parts except during actuation no spring fatigue or wear. Set point is mostly a function of the negative rate Belleville spring variables in snap action electrical have little effect on the set point. Total movement of the Belleville spring compensates for any relocation of the electrical due to case growth consistent set point over temperature change. No linkage utilized no wear which can affect accuracy. VIBRATION RESISTANT - Eliminates Contact Chatter BECAUSE: Belleville spring does not preload the electrical prior to actuation snap action electrical maintains its vibration resistant characteristic. Small mass and inherent stability of the Belleville spring resists chatter caused by vibration. Snap action electrical is ruggedly mounted with minimal bracketry no spring mounted electricals or linkages. HIGH OVER-RESSURE CAABILITY - No Affect on Set oint Accuracy BECAUSE: Belleville spring does not contain the pressure no affect on system or proof pressure capability. The pressure sensing portion bottoms out after actuation and is fully supported pressure sensing parts are designed for high pressure conditions. Limited movement of spring mechanism no overtravel of the snap action electrical due to high pressure. HIGH CYCLE LIFE - Millions of Cycles BECAUSE: Short stroke minimizes wear Belleville spring mechanism is exercised less than.020". Snap action of Belleville spring reduces electrical arc prolongs contact life. ACTUATED Neo-Dyn Industry Drive Valencia, CA tel: fax: Form #089 11/14

9 Neo-Dyn Neo-Dyn ressure, Flow & Temperature Switch Definitions & Terminology Introduction The following definitions and terminology describe the operating characteristics, specifications and other details relative to pressure, flow, and temperature switches. Types of Switches ABSOLUTE RESSURE SWITCH: A switch that compares the pressure being sensed to that of a perfect vacuum. Construction requires the reference chamber to be evacuated. DIFFERENTIAL RESSURE SWITCH: A switch having both a high and low pressure port. Actuation occurs when pressure to the high port exceeds pressure to the low port by a predetermined value. FLOW SWITCH: A Neo-Dyn flow switch senses differential pressure generated by flow through a venturi to actuate an electrical switch at a predetermined flow level. Definitions Absolute ressure - The difference between zero pressure (which exists only in a perfect vacuum) and some known pressure. Absolute pressure may be determined by adding gauge pressure to atmospheric pressure (14.7 psi at sea level). Actuation oint - The point at which electrical switching element is operated on increasing or decreasing pressure. Neo-Dyn considers this point the increasing set point. Ambient ressure (or Temperature) - ressure (or temp-erature) immediately surrounding the switch. Atmospheric ressure - The pressure caused by the weight of air. Atmospheric pressure at sea level is considered to be 14.7 psia (or 29.9 inches of mercury or 407 inches of water absolute.) Burst ressure - Burst pressure is the maximum pressure which may be applied to a switch without causing leakage. ermanent degradation may occur or the unit may become Inoperable if burst pressure is applied. Burst pressure is normally 2Z x to 3 times maximum system pressure. Charge Media - The fluid or gas with which the temperature sensing probe is filled. Critical Set oint - The critical set point is the most important set point of the unit and is held to the closest tolerance. It can be either the actuation (increasing) or deactuation (decreasing) set point. Deactuation oint - The point at which the electrical switching element is operated on increasing or decreasing pressure. Neo-Dyn considers this point the decreasing set point. We hope this data provides the answers to questions which may arise and helps you in selecting a switch. GAUGE RESSURE (AND VACUUM) SWITCH: A switch that compares the pressure being sensed to that of atmospheric pressure. ositive pressure switches sense monitored pressure above atmospheric pressure while vacuum switches sense pressure below atmospheric. TEMERATURE SWITCH: A Neo-Dyn temperature switch is identical to a pressure switch with the addition of a fluid-vapor charged sensing probe. The fluid-vapor charge is exposed to the basic sensor and since probe pressure varies with temperature, discrete temperature settings can be accomplished. Deadband - The deadband, sometimes referred to as differential value, is the change in value between actuation and deactuation set points. Differential ressure - The difference between the two pressures being measured. Direct Mount - A phrase used to refer to the mounting of an instrument directly at the source of the process variable (pressure or temperature) being sensed. - Industry standards have established letter designations for the various electrical arrangements. They are C for SDT, CC for DDT and Z for double break. Form C : Single ole Double Throw (SDT) Switching Element - An SDT switching element has one normally closed, one normally open, and one common terminal. Three terminals mean that the element can be wired with the circuit either normally open (N/0) or normally closed (N/C). Form CC : Double ole Double Throw (DDT) Switching Element - A DDT switching element has six electrical terminals, two normally closed, two normally open and two common. Neo-Dyn uses two independent SDT switching elements. Some units are designed for simultaneous operation whereas, others are for separate operation at different set points. Form Z : Double Break Switching Element - A double break switching has two isolated circuits. Four terminals facilitate wiring one circuit normally open and the other normally closed.

10 Neo-Dyn ressure, Flow & Temperature Switch Definitions & Terminology Electrical Switching Element - The electrical switching element opens or closes an electrical circuit in response to movement by the pressure/temperature sensor. Most Neo-Dyn products are available in SST, SDT and DDT. Non-Critical Set oint - The non-critical set point is the least important setting and the tolerances are not held as close as the critical set point. It can be either the actuation or deactuation point. (Housing) - That part of the instrument which, in varying degrees, protects the mechanism from ambient conditions. Explosion roof - An enclosure which is capable of withstanding an explosion which may occur within, and capable of preventing the ignition of an explosive atmosphere which may surround it. Gauge ressure - Gauge pressure is the difference between atmospheric pressure and a variable pressure. Hermetically Sealed - An enclosure completely sealed from the environment. Neo-Dyn hermetically sealed electrical assemblies are all metal with a glass header. All joints are soldered or welded to insure sealing integrity. Mass Rate of Flow - An expression of flow by weight in a given time, such as pounds per hour (H). Media - The liquid or gas being sensed by the instrument.

Neo-Dyn uses Duont Kapton Type F teflon coated flexible polyimide film as a diaphragm material. Note: Although excellent for most applications, polyimide is subject to cracking after prolonged exposure to water above 140 F. ressure - Force per unit of area. ressure Sensing Element - The pressure sensing element is that component part which moves as pressure increases or decreases, operating an electrical switching element at a predetermined point. Neo-Dyn Nega-Rate pressure switches utilize a diaphragm or piston as a media seal with a Belleville negative-rate disc spring system. ressure Switch - A pressure switch is an instrument designed to convert pressure into motion to operate an electrical switching element thereby making or breaking an electrical circuit. roof ressure (or Temperature) - Normally 1Z\x to 2 times system, it is the maximum momentary pressure (or temperature) including surges, which may be applied to any switch without causing permanent degradation. Remote Mount - A phrase used to refer to the mounting of an instrument away from the source of the process variable being sensed (usually via a capillary tube). Repeatability - Repeatability is the maximum set point deviation of a single pressure switch under one given set of environmental and operational conditions. Special Switch - A unit which is modified outside the limits of a standard catalog item. System (Working) ressure - System pressure is the operating pressure of any hydraulic or pneumatic system. Tolerance - Tolerance is the maximum allowable setting deviation between two or more production units under all specified environmental and operational conditions. Tolerance represents the sum total of setting deviations due to calibration and manufacturing variations, temperature changes, etc. Variable ressure - Changing pressure, generally the pressure which is being measured or controlled. Volume Rate of Flow - An expression of flow by volume in a given time, such as gallons per minute (GM). s - That portion of the unit which comes in contact with the pressure media.

15 Neo-Dyn Repeatability, Accuracy and Maintenance for ressure Switches REEATABILITY Repeatability is the maximum set point deviation of a single pressure switch under one given set of environmental and operational conditions. Since adjustable pressure switches can be set at any discrete set point within its given adjustable range this is the most common performance criteria stated by the manufacturer. A general repeatability statement is that a ITT Neo-Dyn pressure switch will repeat within ± 0.5% of its set point when set in the upper 80% of its adjustable range for set points above 10 psig. Exceptions to this statement could include piston sensor pressure switches and switches whose adjustable range is inches of water. ACCURACY Accuracy is a term generally associated with analog instruments such as transducers and transmitters. Since a pressure switch is meant to give a contact opening or closure at a discrete set point an accuracy statement can only be given if all operational and environmental conditions are clearly defined. For example, what is the accuracy of an Neo-Dyn model 10012C3 when set at 150 psig increasing pressure when cycled between 150 psig and 130 psig for 500 cycles over a temperature range of +40 to +160 degrees Fahrenheit at a cycle rate of 15 cycles per minute. Again, the model, the operational and environmental conditions must all be defined. ITT Neo-Dyn can provide limited testing on some of its models under various test conditions. MAINTENANCE Under normal circumstances ITT Neo-Dyn pressure switches do not require maintenance or recalibration. For critical applications or those where the switches are used in a severe environment, it is suggested a calibration check be performed at intervals based upon actual in service stability data.
