DP4A, EN4A, WB4A

The Amphenol Advanced Sensors Model DP4 Dew Point, WB4 Wet Bulb, and EN4 Enthalpy Transmitters are rugged and compact. Each transmitter uses a capacitive RH sensor and an RTD temperature sensor to compute the dew point, wet bulb, or enthalpy for building automation and process applications. Two linear outputs provide a 4-20mA signal for dew point, wet bulb, or enthalpy, and a 4-20 mA signal for dry bulb. These transmitters are proven performers in Building Automation Systems, BAS, and HVAC applications.
