Model 166 Series are low range differential pressure transducers and transmitters. It features a flame retardant plastic enclosure with a metal backing. The unique design allows it to be used for outdoor environments 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 0-5V, 0-10V, or 2-wire with a 4-20 mA output, fully protected against short circuits and incorrect wiring. In the voltage version, the output can go down to true zero. The units are temperature-compensated. The accuracy can be 1.0%, 0.4% or 0.25% at room temperature. The patented stainless steel sensor provides good corrosion resistance, excellent performance, and long-term stability. Our unique production setup can also make special pressure ranges (e.g. -0.5"WC to +3.5"WC to meet special applications.)
