Dwyer 657C-1 Offers

Rugged and reliable, this relative humidity/temperature transmitter produces separate output signals for both relative humidity and temperature, providing two 4 to 20 mA channels. Delivers ±2% accuracy for humidity and ±1°F for temperature measurements and includes a state-of-the-art integrated polymer film/relative humidity sensor with a thin-film platinum temperature sensor.

Features

Polymer film humidity and thin film RTD temperature sensors offer highly reliable and stable measurements
Rugged die-cast aluminum housing is great for industrial applications

Applications

Cleanroom monitoring
HVAC/R building control monitoring
