Vaisala Dew Point, Enthalpy & Wet Bulb Transmitters HMD/S/W8XD/H/W Series

Vaisala Dew Point, Enthalpy & Wet Bulb Transmitters

 

The Vaisala HMX8XD Dew Point, HMX8XW Wet Bulb, and HMX8XH Series Enthalpy Transmitters are rugged, compact, and ideally suited for monitoring dew point, wet bulb, or enthalpy in commercial HVAC/BAS applications. Using a Vaisala Intercap® RH sensor and an RTD temperature sensor, the unit's microprocessor computes the dew point, wet bulb, or enthalpy. Two linear outputs provide a 4-20mA signal for dew point, wet bulb, or enthalpy, and a 4-20 mA signal for dry bulb, temperature.
