Convert A Pressure Signal to an Electrical Output
Featured Product from Tecmark Corporation
Tecmark Series 3000, 3900 and 4000 Pressure Switches convert a positive or negative pressure signal (range 2” W.C. to 100 PSI) to an electrical output. In response to a change in pressure, movement of an elastomeric diaphragm opens or closes an electrical circuit based on a predetermined pressure set point. Series 3000, 3900 and 4000 Pressure Switches are commonly used as an interlock device to sense air, gas or water pressure at a specific point.
