HMD/W 60T/70T
OPTIMAL ENERGY MANAGEMENT
The duct and wall-mounted HMD/W 60 and
HMD/W 70 transmitters are designed for monitoring
relative humidity and temperature in building energy
management systems. The combination of high
accuracy, stability and reliable operation makes these
products the ideal choice for demanding energy
management applications.
The duct mount 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 novel feature of these duct mount transmitters is
the ability to remove the electronics without disas-
sembling the unit from the duct.
The HMD/W 60 and HMD/W 70 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 the HMI 41 humidity calibrator. The calibration
can be done in seconds with a single potentiometer
without disturbing operation. This saves hours of
maintenance time and ensures high system accuracy.
