Gems Sensors Series Pressure Switch
Economical Miniature Pressure Switches
Quick Specs...
- 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.
