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

Product Description

Model 166 series cost effective pressure transducer are low range dp transducers and transmitters. It features a flame retardant plastic enclosure with a metal backing. The unique design makes it can be used at outdoor environment and with easy access to zero and sensitivity adjustments. The dp transmitter price here has an competitive edge compared with related products in this field.

The pressure range of the low cost pressure transmitter covers from 0.1″WC to 100″WC, unidirectional or bidirectional. The output can be 3-wire 0 to 5V, 0 to 10V, or 2-wire 4 to 20 mA, fully protected against short

circuit and incorrect wiring.  In the voltage version, the output can go down to true zero. The units are temperature compensated. The accuracy can be 0.6%, 0.4% or 0.25% at room temperature.

The patented stainless steel cost effective pressure sensor provides good corrosion resistance, excellent performance and long term stability.

Our unique production setup can also make special pressure range (e.g. -0.5″WC to +3.5″WC) to meet special applications.
