3 Temperature Supplemental Guide Sensor Types Temperature Switch Products Local Mount Local mount type temperature switches are installed in the pipe or vessel. ln this type of sensor, the filling fluid surrounds the bellows. A negative temperature change forces the fluid to contract-expanding the bellows to actuate the switch. Positive temperature changes produce the opposite effect. Remote Bulb & Capillary Remote temperature switches allow the switch enclosure to be placed up to 25 feet from the media. These models use a bulb and capillary sensing device which may be ordered in standard six and 2 foot lengths. Extra lengths up to 25 feet are available. Six and 2 foot sensors can be copper or stainless steel with or without protective spiral-wound armor. The 25 foot lengths are armored stainless steel only.

All are available with one or two adjustable temperature set points and fixed or adjustable differential.

4 Supplemental Guide Temperature Switch Products General Data Barksdale was the first manufacturer to offer effective ambient compensation in electromechanical switches revolutionizing temperature switch accuracy through extreme temperature changes. In a liquid-filled bulb and capillary system, ambient temperature changes affect the expansion of the fluid resulting in false temperature sensing. An extreme ambient change from -65 F to + 65 F will decrease the accuracy of most switches by 20% or more. Or, if the temperature changes only 70, accuracy can be decreased by 5%. ±% Accuracy From Barksdale Bulb and capillary configurations overcome ambient temperature swings through stacking of precision, concave bimetal washers. An ambient temperature change causes the liquid fill in the bulb, capillary and bellows to expand or contract, an equal and opposite reaction occurs between the washers. This compensates for ambient temperature change assuring high repeatable accuracy even under wide ambient temperature swings. By reacting to ambient temperature changes as extreme as - 65 F to + 65 F, the accuracy of the mid-60% of the adjustable range is still within ±% of full-scale. Accuracy at constant ambient is ±0.5% full scale. Local mount temperature switches are not affected by ambient temperature changes in the same way as bulb and capillary types. All of the filling fluid is exposed to the media temperature the bulb is sensing. Therefore, there is no ambient temperature influence on the filling fluid. Ambient Temperature Compensation Comparison Curve Good Response Time Select for Mid-Range Setting For optimum repeat accuracy in areas of extreme temperature change, select the switch range that enables the desired set point to fall in the mid 60% of the adjustable range. 2

5 Temperature Supplemental Guide General Data Temperature Switch Products Differential (Actuation Value, Dead Band, Hysteresis) BY CLASS OF ELECTRICAL SWITCH USED IN BARKSDALE TEMPERATURE SWITCHES Differential tolerances on temperature switches are due to manufacturing tolerances on limit switches and sensing elements. The differential of each temperature switch will remain fixed within the tolerances shown. Test conditions and media used could affect differential. Hermetically Sealed Switches Barksdale Hermetically Sealed Temperature Switches were created for use in hostile environments where exposure to elements such as salt air, hydrogen sulfide and other corrosive agents and atmospheres might cause contact deterioration and switch failure. The switch elements meet the requirements for Class I, Division II hazardous areas. The Barksdale hermetically sealed switch element is the same size as most nonsealed micro-switches, making this modification of our standard switches simple and inexpensive.. Select the standard unit with the desired characteristics. 2. Refer to the catalog sections showing the actuation value (differential) and electrical rating of switch elements by class. (The Class of Electrical Switch for Hermetically Sealed switch elements is either AA, CC or HH.) Select the class (AA, CC or HH) desired. 3. Change the standard catalog number as follows: - Prefix the catalog number with H. - Substitute AA or HH for the standard switch element designation. - Drop any -UL suffixes. Examples: - Standard Catalog number T2H-H5 - Hermetically Sealed numbers are HT2H-AA5, HT2H-CC5 or HT2H-HH5 Sensing Element Adjustable Approximate Differential (Actuation Value, Deadband, Hysteresis) Range - F by class of switch element Bulb & Capillary Type Sensor B GH, H J K L M S Adjustable G** Can be AA HH CC to from reset after MTH to T2H to TX to T2X to Local Mount MLH -20 thru thru L2H -45 thru thru LX -45 thru thru *Differential values are the same for copper and stainless steel **-RD Models ***T2H, T2X, L2H Models Electrical Rating (Current given in Amperes) () For standard models the electrical ratings are listed on each page under lectrical Characteristics?

6 Supplemental Guide Temperature Switch Products General Data Temperature Conversion Table Find in the center column the number of the known temperature. If the known temperature is in Fahrenheit, the Centigrade equivalent is in the left hand column. If in Centigrade, the Fahrenheit equivalent is in the right hand column. The basic conversion formulas are: C = F - 32 X 5/9, OR C = F - 32 F = C X 9/5 + 32, OR F = C X C F/ C F C F/ C F C F/ C F C F/ C F Temperature Switch Operation and Safety WARNING Product must be installed in accordance with applicable NEC, ASME and local regulations as applicable including those that apply to installations in hazardous locations requiring explosion proof enclosures or similar construction. The temperature limitations shown on the individual catalog pages for the specific switch must not be exceeded. These temperatures must take into consideration the possible maximum system temperatures encountered. The maximum allowable pressure on the sensor is 300 psi. Over 300 psi, use suitable thermowell. The fluid used must be compatible with the materials of construction. Special cleaning and packaging may be required for special media such as oxygen. Consult factory. Temperature switches are not of sanitary construction and the fill fluid is toxic. Therefore, sensors should not be in contact with materials intended for ingestion unless suitable thermowell is used. Sensors listed in this catalog are filled with silicon oil. When silicon oil is combined with strong oxidizing agents, including (but not limited to) chlorine, nitric acid, and hydrogen peroxide, a spontaneous chemical reaction, ignition or explosion can result. When temperature switches containing fluid are used in such service, thermowells must be used. The electrical load through the temperature switch must not exceed the values shown in the catalog for the specific switch involved. Shock and vibration may affect the switch performance. Therefore, shock and vibration should be minimized. Consult factory for assistance. Troubleshooting and Maintenance Troubleshooting of the switch must be in strict compliance with the procedure set forth on the Troubleshooting and Maintenance section of this catalog. Field repair of UL, CSA or other listed units will void the UL or CSA listing of the repaired unit. Barksdale, Inc. components must not be used in life support applications of any kind. Failure to observe these warnings could result in serious injury or damage. 32 Fruitland Avenue Los Angeles, CA Fax: See Barksdale s Standard Conditions of Sale Specifications are subject to modification at any time Bulletin #T0027-B 09/ Printed in the U.S.A.

7 Temperature Temperature Switch Accessories Thermowells, Split Nut, Union Connector, Capillaries Standard Local Mount Standard Local Mount /2 NPT threads Sensor submersible in pressurized vessel; pressure range through 300 psi. Example: MLH-H20S Sensor 3/4 NPT threads Thermowell Option: -W: Brass -WS: 36 Stainless Steel #0 Set screws (2); secures switch in thermowell; can be rotated 360 in well. Sensor submersible in pressurized vessel; pressure range: 000 to 7000 psi, depending on material and temperature. NOTE: Barksdale standard models cannot be field converted to add a Barksdale thermowell. To order a standard temperature switch with thermowell, add -WS to the model number. Example: MLH-H20S-WS Example: MLH-H20S-WS To order replacement temperature switch for thermowell models, less thermowell, add -Z8 to model number. Example: MLH-H20S-WS-Z8 Thermowells for High Pressure and Harsh Environments Thermowells for Remote Bulb and Capillary Models Only All electromechanical temperature switches may be used with a thermowell when pressures exceed 300 psi, if high velocities are present and with corrosive or abrasive medias. Thermowells also allow removal of the temperature switch or sensor without loss of contained media. When using a thermowell with a local mount temperature switch, two set screws are provided to secure the switch in the well allowing 360 rotation for easier electrical connection and readability. The use of a thermowell may increase response time to temperature change. By using heat transfer material, the increase can be kept to a minimum.
