Model 657C-1 Relative Humidity Transmitter (Model 657C-1)

Model 657C-1 Relative Humidity Transmitter (Model 657C-1)

model 657c-1 relative humidity/temperature transmitter

dual channel design for simultaneous 4-20 ma output signals – conduit housing

the series 657 transmitters provide two 4 to 20 ma channels to produce separate output signals for both relative humidity and temperature. These devices deliver ±2% accuracy for humidity and ±1°f for temperature measurements. Stainless steel probe can be easily mounted to most ductwork using either of the two optional kits below.

product applications

cleanroom monitoring

hvac/building control monitoring
