Series Pressure Switch PS41 Gems Sensors

Gems Sensors Series Pressure Switch

These miniature pressure switches are designed for demanding applications where space and/or price are strong concerns. The switches utilize a piston/diaphragm design, which incorporates the high proof pressure of piston technology with the sensitivity of diaphragm designs. Switches are field adjustable via an Allen head screw that is hidden to protect against unauthorized tampering.

  • 3.5 to 100 psi (0.24 to 7 bar)  

Overview / Design Principle:

These miniature pressure switches are designed for demanding applications where space and/or price are strong concerns. The switches utilize a piston/diaphragm design, which incorporates the high proof pressure of piston technology with the sensitivity of diaphragm designs. Switches are field adjustable via an Allen head screw that is hidden to protect against unauthorized tampering.

5 psig (0.28 bar) + 10% of setting 

* These numbers are for the standard microswitch. With either the -SP or 10A option, the values are typically 20% greater than those listed. With the -RD option, the values will be typically 25% less than those listed. In certain applications, deadband can be tailored and controlled to customer specifications.
