Solid State Pressure Switch Measures Gases and Liquids

American Sensor Technologies, Inc. (‘AST’) has developed a superior quality, high-accuracy Solid State Pressure Switch for the measurement of gases and liquids compatible with stainless steel. Constructed of stainless steel, the rugged design of Model 1000 units make them ideal for industrial, hydraulic, refrigeration, off-road and agricultural applications such as boiler controls, HVAC, filtration, and pipeline gas instrumentation.

Offering excellent, long-term stability, Model 1000 pressure switches feature a compact design with excellent long-term stability. Its one-piece diaphragm is free of internal O-rings, welds or fill fluids, eliminating the chance of process contamination. A high level of EMI/RFI protection (100V/m) shields the units against electrical noise and interference. Heavy-duty relay contacts offer electrical isolation up to 500VDC. Model 1000 units also have wide operating temperature ranging from -40 to 85ºC (-40 to 185ºF).

The competitively priced Model 1000 offers a factory set switching point and hysteresis. Units offer switching capability of 1 amp @24V DC or 0.5 amps @ 125V AC, max. Open or closed output is provided, based on customer’s defined switching point. At lower currents, pressure switches exhibit a high switching cycle life of 2 million pressure cycles. Units are available in pressure ranges up to 10,000 psi.

Pricing for the AST Series of pressure sensors begins at $250 with low quantity discounts available. For additional information, please visit American Sensor Technologies website at www.astsensors.com or email inquiries to info@astsensors.com
