As a differential pressure transmitter manufacturer, Alpha instruments Inc specialized in the development and manufacture of low pressure differential pressure sensor, which were applied in HVAC, Critical Environments, Medical Industry, Semiconductor Equipment, etc.

 

Product Description

The Model 164 Series pressure sensor ranges vary from 0.1 in w.c. to 100 in w.c. unidirectional and 0.05 in w.c. to 50 in w.c. bidirectional. Wiring time is reduced with the removeable terminal block. Each unit is fully protected against short circuiting and incorrect wiring.

 

The Model 164 Series stainless steel pressure sensor are available for pressure range  from 0.1″WC full scale to 100″WC full scale, Both unidirectional and bidirectional pressure ranges are offered.

 

The output of the Model 164 Stainless Steel Pressure Transducer is available in two versions: 0 to 5VDC and 0 to 10VDC, where 0VDC is true zero without offset. The output of Model 164 Stainless Steel Pressure Transmitters is 4 to 20 mA. All units are temperature compensated.

 

The patented variable capacitance pressure sensor is constructed by stainless steel and glass, no glue or other organics. That provides excellent performance, corrosion resistance and long-term stability.

 

Additionally, our unique production setup allows us to accommodate special orders for nonstandard pressure ranges  (e.g. -0.5″WC to +3.5″WC).
