Vaisala HMW60/70 Humidity and Temperature

Humidity and Temperature

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.

▪ 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 temperatureonly transmitters HMW 60T/70T
▪ NIST traceable (certifi cate included)
