Model 168 intrinsically safe Differential Pressure Transducer

Product Options:


Product Description

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 rugged and very reliable, good for many industrial applications.

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.
