As a pressure transducer supplier, Alpha instruments Inc was founded in 2005, in Massachusetts, US. We specialized in the development and manufacture of low differential pressure transducer, which were applied in HVAC, Critical Environments, Medical Industry, Semiconductor Equipment, etc.

 

Product Description

The low cost pressure sensor Model 161 Series are low range differential pressure transmitters and transducers. Each unit features a stainless steel pressure sensor, a stainless steel back cover and a plastic enclosure, which meets the NEMA 1 requirement. The electrical terminal screws and adjustment holes are concealed beneath a detachable plastic cap. All units are fully protected against short circuiting and incorrect wiring. The differential pressure sensor price is matched with its high-quality here.

 

The Model 161 Series dpt sensors are available for full scale pressure range from 0 to 0.1″WC till 0 to 100″WC. Both unidirectional and bidirectional pressure ranges are offered.The output of the Model 161 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 161 Pressure Transmitters is 4 to 20 mA. All units are temperature compensated. The accuracy can be 0.6%, 0.4% or 0.25% at room temperature.

 

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).
