Pressure Switches

Transcat distributes the most reliable pressure switches for general purpose, air/water, gas and differential applications. The pressure switch will detect changes and open or close an electrical contact according to a predetermined set point. Differential switches sense pressure from both a low and a high pressure port and respond to the difference. Switches may be categorized according to their technology, such as diaphragm or piston. Our pressure device selection features switches with a wide scope of ranges to support virtually every application. We also offer Dwyer switch/gage combination instruments that measure and control positive, negative or differential pressures of air and gases.
