Model 166 Cost-effective Differential Pressure Transducer

Model 166 series cost effective pressure transducer are low range differential pressure 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 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 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.
