As a pressure transmitter company, Alpha instruments Inc specialized in the development and manufacture of various low pressure differential pressure sensor.
Product Description
The Model 165 Series capacitive pressure transducer for building energy management systems, environmental pollution control, oven pressurization, lab and fume hood control, HVAC and VAV applications.
The Model 165 Series capacitive pressure transmitter is 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 165 capacitive type 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 165 capacitive transducer for pressure measurement 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).
