Cleanroom Pressure Sensor AI164
Pressure Medium: Air/Gas
Sensor Type: Gauge, Differential
Supply Voltage: 5V
Output Signal: Voltage, 4-20 mA
Pressure Range: Under 4” H2O
Kind: Packaged Transducer

Model 164 Series are low range differential pressure transducers and transmitters. It features a stainless steel enclosure and a plastic top. The additional small cap covers the terminal screws and adjustment holes. The pressure range covers from 0.1"WC to 100"WC, unidirectional or bidirectional. 

The output of the 164 Series can be 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. This part is a drop-in replacement for Ashcroft RXLdp, at a lower price!
