Pressure Switches & Sensors

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

Gems offers a choice of pressure switches, water pressure switches from compact cylindrical models for OEM use, to larger, enclosed units for rugged process applications. These water pressure 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 pressure 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.
