HMT360 Series Intrinsically Safe Humidity and
Temperature Transmitters
The Vaisala HUMICAP
®
Humidity
and Temperature Transmitter Series
HMT360 are the ideal solution for
measuring humidity in hazardous
areas. They operate safely and
reliably even in the most hazardous
classi cations. The HMT360
transmitters' proven performance
and technology conform with
rigorous international standards.
Intrinsically safe
The entire HMT360 transmitter can
be installed directly in explosive
areas. It can withstand continuous
exposure to potentially explosive
environments that contain  ammable
gases or dust.
Customized confi guration
Due to the microprocessor based
electronics, options and accessories,
the HMT360 series is truly  exible.
The Vaisala HUMICAP
®
Humidity and Temperature Transmitter HMT361 wall mount
transmitter, shown with six probe options, is designed specifically for hazardous and
explosive environments.
Customers may specify the
transmitter con guration when
ordering the instrument, however
changes in con guration can also
easily be made in the  eld.
Interchangeable probes
The HMT360 offers six probe options
for various applications:
HMP361 - wall mount
HMP363 - con ned spaces
HMP364 - pressurized spaces
HMP365 - high temperature
HMP367 - high humidity
HMP368 - pressurized
pipelines
The interchangeable probes
enable fast and easy removal or
re-installation when required.
Calibration, for example, is easy
to perform due to the modular
structure. All calibration coef cients
are included in the probe unit itself,
which means that probes can be
switched between transmitter bodies
without losing the accuracy.
Optimized sensors
In addition to the standard Vaisala
HUMICAP
®
Sensor, an application
speci c, very chemically durable
sensor is also available.
Long-term solution
The HMT360 transmitters are an
investment; their rugged design,
combined with trouble-free
operation, ensure a long-term
solution for monitoring humidity and
dewpoint in explosive environments.
Customized calibration and
maintenance contracts for the
HMT360 series are available on
request.
