HMD60/70 Humidity and TemperatureTransmitters for ducts in HVAC applications
Features/Benefi ts
▪ Full 0 ...100 %RH measurement ▪ Accuracy up to ±2 %RH ▪ True two-wire transmitters
with 4 ...20 mA loop powered output (HMD60) ▪ Selectable signal output of 0 ...1 V,0 ...5 V or 0 ...10 V (HMD70) with optional current module also 0 ...20 mA (HMD70)
▪ Vaisala HUMICAP Sensor for excellent accuracy and long-term stability,negligible hysteresis and resistance to dust and most chemicals.▪ Temperature compensated ▪ IP65 (NEMA 4) housing
▪ Also available as temperatureonly transmitters HMD 60T/70T
▪ NIST traceable (certifi cate included)
Vaisala HUMICAP Humidity and Temperature Transmitters HMD60 and HMD70 are
designed for use in air conditioning applications where accurate and stable control
of relative humidity and temperature are required
The duct mounted Vaisala HUMICAP Humidity and Temperature Transmitters HMD60 and HMD70 are designed for monitoring relative humidity and temperature in building energy management systems.The combination of high accuracy,staility and reliable operation,make these products the ideal choice for demanding applications.
Resistant to chemicals and dust
The duct mount HMD60 and HMD70 transmitters can also be used in many industrial humidity monitoring applications,where their stability and resistance to chemicals and dust are of great value.A useful feature of these duct mount transmitters is the ability to remove the electronics without removing the unit from the duct.
Measures both humidity and temperature
The HMD60 and HMD70 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.
