Pressure Switches

From 40 mbar to 400 bar (2 to 6000 psi), Gems™ Pressure Switches Cover A Wide Range of Applications

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 such as transducers.

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.
