. Sensors & Controls GEMS Pressure Switches Cover A Wide Range of Applications ► General, Vacuum, Differential, Specialty ► Field-Adjustable or Factory Set Switches ► High Proof Pressure GEMS offers a choice of pressure switches, from compact cylindrical models for OEM use, to larger, enclosed units for rugged process applications. These switches are ideal for the filtering process of coolants in the machine tool industry, use in transmissions of off-highway vehicles and as redundant systems with existing monitors Unique Piston/Diaphragm Design A piston/diaphragm design, incorporating the high proof pressure of piston technology allows these switches to operate with the sensitivity and accuracy of a diaphragm design. Repeatability ranges from 0.25 percent to 5 percent of the set point. Many Materials To Choose From Enclosures include aluminum, stainless steel, brass, reinforced plastic and zinc-plated steel. Wetted parts include a diaphragm available in Buna-n, Teflon® coated Kapton®, stainless steel, PTFE, EPDM or Viton® and a pressure port available in stainless steel, brass, zinc or aluminum. Pressure Switch Option Descriptions G: Gold contacts are usually associated with TTL input devices. They provide decreased contact resistance, which results in more reliable microswitch rated 10 Amperes differential, which results in a larger deadband than listed in the standard catalog pages. IP: Ingress Protection is provided by either an epoxy sealed cap (IP65) or silicon wire seals (IP66). On some models, this option is only available with RB: Rubber Boot is designed to or cable size by the customer and sealed with an appropriate termination consists DE: Deutsch male termination FS: Gems will preset switches within repeatability limits listed on the specific product catalog page. systems that need a small pressure switch life. It is a pressed in part that has an SR: The spiral restrictor option heavily dampens pressure system, which prevents false signaling and premature wear. pressure settings below 1500 slows the response time of the pressure switch.

Selection Guide Plastic Diaphragms Option K or Standard Teflon® Coated Kapton® (Polyimide) Teflon® is compatible with almost every liquid and gaseous media. Kapton® has very stable physical properties over a wide pressure switches that exhibit very little set point shift due to temperature extremes. Kapton® possesses exceptional fatigue strength but is very stiff which results in wider but more stable deadbands than most Elastomer Diaphragms Elastomers offer incredible sensitivity coupled with extremely long life. This results in stable set points over the life of the pressure switch as well...
