How To Select A Pressure Gauge Selecting a Palmer Pressure Gauge: The subjects listed below can be used as a guide to ensure that proper consideration is given to all factors affecting the choice of a pressure gauge. Caution: Operating conditions including, but not limited to, system pressure, media compatibility and ambient conditions must be considered when selecting gauges and accessories. Improper selection and use of gauges could cause gauge failure and lead to possible property damage and personal injury. Refer to ANSI B40.1 for the correct selection and use of gauges. This document may be obtained from ASME at: For General Pressure Terminology see the diagram on pg 4. Case Construction: If your environment is severe or corrosive, a stainless steel case may be indicated. If you are considering a gauge which will be monitored by an operator, a process gauge with a solid front construction will provide an extra measure of safety. If you require in-house calibration, specify a micrometeradjustable pointer and bayonet ring case. While a large case will be easier to read, case size considerations are generally driven by available space, connecting considerations, and accuracy requirements. See Dial Size Reference Chart on page 2 for specific size gauges. Environmental Considerations: Ambient temperature, humidity, vibration, corrosive gasses, and weather must all be considered when selecting a pressure gauge. The environmental temperature limits for most Palmer gauges are shown in the table below. Generally all Palmer Pressure are dustproof, and filled gauges are waterproof. Environmental Limits Damping Fluid Recommended Temperature Range -13 to 150 F -25 to 65 C Glycerine 60 to 150 F 15 to 65 C Silicone -50 to 150 F -45 to 65 C Fluorolube -76 to 150 F -60 to 65 C Neobee M20 0 to 400 F -17 to 200 C Working Fluid: If the working fluid is corrosive, stainless steel wetted parts should be considered; see All Stainless Steel pages 6-9. In extreme cases, it may be necessary to use K Monel wetted parts or to use a diaphragm seal. If pressure pulses are expected, consider the use of a snubber, which can be field adjusted for different working fluid viscosities. This will also limit the rate of fluid loss in the unlikely event of gauge mechanical failure. See individual gauge pages for working fluid temperature limits. If high temperatures are expected, and for all steam applications, a steam syphon will reduce the exposure of the instrument to high working fluid temperatures. See page 25 for more information. Needle Valves are used to regulate pressure, Ball Valves are designed to turn on or off the flow of pressure, allowing removal of a gauge for calibration or replacement. See page 24 for information about these products. Fearless : These gauges are designed for use in applications requiring the vibration and pulsation damping qualities of a filled gauge. The Fearless provide filled gauge performance with all the advantages of dry gauges, such as in situ calibration, field crystal replacement, plus no potential leaks. See pages 6-7 for details about our Fearless. WARNING: Caution should be used when selecting a fluid filled gauge for any applications using oxidizing mediums such as chlorine, oxygen, hydrochloric or nitric acid, hydrogen peroxide, and others. Glycerine or silicone could result in a spontaneous chemical reaction or explosion when combined with these agents. Optional Fluorolube Filled or Fearless Dampened Movement dry gauges (pages 6-7, & 12-13) are recommended. Wetted parts should be cleaned before use. a diaphragm seal may be needed. Mounting: As a rule, all gauges are available in Stem Mount, Lower Connected (mounting code L), and Stem Mount, Back Connected (mounting code B). Not all gauges are available in all mounting configurations. For a sketch of mounting types see the Mounting Codes Examples illustration on page 4. If your application involves excessive vibration or requires a large gauge, consider specifying a gauge which is mounted by some method other than the stem; for example, a U-clamp (U) or Surface Mount (I) gauge. This will reduce the stress on the stem and promote reliable operation. Connection: Palmer Pressure are available in a wide variety of connections. NPT threads are the standard configuration. Optional adaptors also available. If you have a requirement for a connection not listed, contact Palmer Customer Service. Range: Select a range so that the expected operating pressure falls in the middle half of the gauge (25% to 75% of full scale). If short duration pressure pulses are expected, the range may need to be increased to avoid damage to some types of gauges. Accuracy: Select a gauge with sufficient accuracy to satisfy your requirements. Liquid filling a gauge reduces the accuracy of that gauge; check the individual pages for available accuracy. Oxygen Service: For gauges requiring Oxygen Service please contact our Customer Service Department. 3

4 Pressure Identification Guide How To Identify A Palmer Pressure Gauge Palmer Pressure are ordered by part number. The part number is composed of several elements which consist of one or more symbols or letters. To identify the Palmer Pressure Gauge which best meets your requirements, use the table on pg 5 as a guide. Specific configurations and option information pertaining to the different types of pressure gauges is on each catalog page, and will guide you in the selection of the following: 1) Case Size 2) Case Material / Style 3) Element Material 4) or Filled 5) Mounting Type (See Mounting Code illustration below) 6) Connection Type 7) Range and Scale, refer to product pages 8) Options, using the Options Table on each page For example a typical Part No. for a Palmer Pressure gauge would look like this: 40SSWLH60#L. This is a 4" (40), Stainless Steel Case (S), Bayonet Connected Bezel Ring Gauge, with All Stainless Steel working parts (S). It is Fluid Filled (W), and Stem Mounted, Lower Connected (L), with 1/2" NPT threads (H). The dial is marked in pounds per square inch and graduated from 0 to 60 PSI (60#). The final code indicates that this gauge will be filled with Fluorolube (L) instead of the standard glycerine fill. The X option code should be used for any option request not indicated on the list. Please note that not all configurations are available! The total possible combinations would exceed two million! After reviewing the general information in How to Select a Pressure Gauge on page 3, refer to the pages in this catalog regarding the specific type of pressure gauge you want. On these pages you will find the ordering guide for that specific gauge. The table on page 5 serves as a general guide with description and option availability for how to construct your part number.

17 Sliding Contacts - Electrical sliding contacts guarantee accurate operation within a controlled hysteresis. They can be sensitive to vibration, and slow pressure changes may cause an electrical arc, reducing their working life. Specialty Electrical Contact Point Options Magnetic Snap-Action Contacts - Offers guaranteed reliable operation of gauges under severe vibration. The magnetic action uses a click operation which improves contact capacity and life, and is less sensitive to vibration. The power required to overcome the magnetic resistance causes an hysteresis at set-point between 2% to 5% of full scale value.
