Convert a Pressure Signal to an Electrical Output

Tecmark Pressure Switches are available in various configurations for air, gas and liquid sensing applications. Tecmark switches can sense pressures as low as 2" w.c. up to 100 PSIG with electrical ratings up to 25 amps. Multiple sample fitting configurations and diaphragm materials are available without the need for custom manufacturing.
