MODE D'EMPLOI HMW60 VAISALA
HMW60/70 Humidity and Temperature Transmitters for wall mounting in HVAC applications

Vaisala HUMICAP® Humidity and Temperature Transmitters HMW60 and HMW70 are designed for use in air conditioning applications where accurate and stable control of relative humidity and temperature are required.
Features/Benefits
Accuracy up to ±2 %RH
True two-wire transmitters with 4 ... 20 mA loop powered output (HMW60)
- Selectable signal output of 0 ... 1 V, 0 ... 5 V or 0 ... 10 V (HMW70)
Vaisala HUMICAP® Sensor for excellent accuracy and long-term stability, negligible hysteresis and resistance to dust and most chemicals.
Temperature compensated
Also available as temperature-only transmitters HMW 60T/70T
NIST traceable (certificate included)
The wall mounted Vaisala HUMICAP® Humidity and Temperature Transmitters HMW60 and HMW70 are designed for monitoring relative humidity and temperature in building energy management systems. The combination of high accuracy, stability and reliable operation, make these products the ideal choice for demanding applications.
Measures both humidity and temperature
The HMW60 and HMW70 transmitters are available in three models: U for humidity measurement-only,
Y for humidity and temperature measurement, and T for temperature only.
Fast, on-site calibration
The accuracy of the transmitters is simple to check using either the Vaisala HUMICAP® Hand-Held Humidity and Temperature Meter HM70 or the Vaisala HUMICAP® Humidity Indicator HMI41. The calibration can be done in seconds with a single potentiometer without disturbing the operation, resulting in great savings both in maintenance time and costs.
