As one of the pressure transducers suppliers, Alpha instruments Inc specialized in the development and manufacture of low differential pressure sensor. Till now, the quality of alpha transducer and alpha transmitter has won wide range of praise from its customers worldwide.

Product Description

Different from Model 167 series negative pressure transmitters, Model 168 series intrinsically safe pressure transducers are low range differential pressure transducers and transmitters with NEMA 4 (IP-65) rated aluminum enclosures. They are very r ed and very reliable, good for many industrial applications, such as the hvac differential pressure transmitter.

The pressure range 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 intrinsically safe 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.
