Model 657C-1 relative humidity and temperature transmitter is housed in a die-cast aluminum protective enclosure with a gasketed cover. This dual-purpose device includes two two-wire circuits to simultaneously produce separate 4-20 mA output signals for relative humidity from 0 to 100% and temperature from 32 to 212F. Accuracy for humidity is ±2% from 10 to 90%, and for temperature it is ±1F over the full range.
