Vaisala HUMICAP® Humidity and Temperature Transmitter Series HMDW110 measure relative humidity and temperature in multiple HVAC applications. The series includes transmitters for duct mounting, IP65-classified wall transmitters, and outdoor transmitters with integrated radiation shields.
♦ Accurate humidity and temperature transmitters for measurements in HVAC and cleanroom applications
♦ Outdoor transmitter with professional-grade radiation shield
♦ Proven HUMICAP® 180R sensor for superior long-term stability ±2 %RH accuracy
♦ 3-point NIST traceable calibration (certificate included)
♦ On-site calibration with HM70 Hand-Held Meter or PC connection
♦ Current output (4 .... 20 mA)
♦ Default output parameters are relative humidity and temperature. Dew point temperature, wet bulb temperature, and enthalpy outputs selectable with a PC connection.
The cost-efficient HMDW110 series transmitters are equipped with trusted HUMICAP® 180R sensors. The sensor's superior long-term stability minimizes maintenance needs throughout the transmitter's lifetime. If necessary, the transmitter can be field-calibrated using either an HM70 Hand-Held Humidity and Temperature Meter, or a PC connection.
The integrated radiation shield of the outdoor models HMS110 and HMS112 enables unrivaled measurement performance. It reduces the impact of sunshine on temperature and humidity measurements, and ensures measurement accuracy in outdoor conditions. The most popular control parameters in free cooling - dew point temperature, wet bulb temperature, and enthalpy - are available as output parameters.
The HMD110 and HMW110 transmitters can be ordered with a catalytic HUMICAP® sensor HUMICAP® 180V. The catalytic sensor improves stability especially in hydrogen peroxide sterilized environments where repeated condensation is expected. An optional panel display can be added for remote monitoring. Transmitters can be installed into difficult-to-reach locations, while measurement data can be read from a more convenient spot.
