Vaisala INTERCAP
®
Humidity and Temperature
Transmitter Series HMW80
The two- and three-wire Vaisala
INTERCAP
®
Humidity and
Temperature Transmitter Series
HMW80 is designed for use in energy
management systems in buildings.
They combine excellent stability with
reliable operation. The HMW80 is
easy to install: wire it to the terminal
block at the transmitter bottom and
close the housing with a snap-on lid
to cover the electronics.
Low Maintenance Costs
The HMW80 humidity transmitters
use the Vaisala INTERCAP
®
Sensor
– an interchangeable capacitive
humidity sensor. The transmitters
require no recalibration if the sensor
is changed. This means great savings
in overall maintenance costs. The
sensor is also insensitive to dust as
well as to most chemicals.
The HMW80 combines excellent stability with easy installation and reliable operation.
Measures Both Humidity
and Temperature
The HMW80 transmitters are
available in four models: HMW82
and HMW83 transmitters measure
both humidity and temperature.
They measure humidity with a
±3 %RH accuracy and with a stability
of ±3 %RH over 5 years. The
accuracy of the temperature
measurement is ±0.5 °C. Two other
models, TMW82 and TMW83,
measure temperature only.
Both 2- and 3-wire transmitters
are also available: HMW82 and
TMW82 are 2-wire (4 … 20 mA loop
powered) transmitters, and HMW83
and TMW83 are 3-wire (0 … 10 V)
transmitters.
