Relative humidity/temperature transmitter.
The Model 657C-1 Transmitter features the same circuit design as the 657-1 providing two 4-20 mA channels to produce separate output signals for both relative humidity and temperature. However, this model is housed in a tough die cast aluminum protective conduit enclosure with gasketed cover.
