Vaisala HMW110 / HMD110 / HMS110 High-Accuracy HVAC Humidity Transmitters
High-accuracy HUMICAP® 180R humidity and temperature transmitters for HVAC in three mounting styles — wall (HMW110/112), duct (HMD110/112) and outdoor with radiation shield (HMS110/112). ±2 %RH, 4 … 20 mA or Modbus RTU, 3-point traceable calibration.
Description
One measurement platform for the whole air-handling system: the same HUMICAP® 180R sensor and electronics in a wall-mount transmitter for rooms, a duct-mount probe for supply and return air, and an outdoor version with integrated radiation shield for fresh-air and economiser reference. Temperature-only versions (TMW/TMD) are also available.
Key features
- ±2 %RH accuracy, Pt1000 temperature sensor (±0.2 °C at +20 °C)
- 3-point traceable RH calibration and 1-point T calibration, certificate included
- 4 … 20 mA loop-powered or Modbus® RTU output
- Display and non-display models; M12 connector option on wall models
- Calculated dew point, wet bulb temperature and enthalpy
- IP65 housing; outdoor HMS110 with integrated radiation shield
