The HMT330 transmitter family has the solution for demanding industrial humidity
measurements.
The Vaisala HUMICAP® Humidity and
Temperature Transmitter Series
HMT330 is designed for demanding
industrial applications where stable
measurement and wide customization
possibilities are important.
Vaisala HUMICAP®
performance
The HMT330 series incorporates
Vaisala’s 30 years of experience in
industrial humidity measurement. The
sensor measures accurately and
reliably and is immune to particulate
contamination and most chemicals.
Chemical purge minimizes
effects of contaminants
In environments with high
concentrations of chemicals and
cleaning agents, chemical purge helps
to maintain the accuracy between
calibration intervals.
Chemical purge involves heating the
sensor to remove harmful chemicals.
The function can be initiated manually
or programmed to occur at set
intervals.
Graphical measurement trend
and history display
The HMT330 can be ordered with a
large numerical and graphical display,
allowing the user to easily monitor
measurement trends and 1-year
history.
Data collection and transfer
to PC
The recorded measurement data can
be viewed on the display or transferred
to PC with Windows®-based software.
The display shows measurement trends and
history up to 1 year.
Flexible calibration
Many ways to install
The HMT330 instruments are factorycalibrated at six humidity points.
Mains and DC power options, and
several mounting accessories make it
easy to install the instrument.
A quick one-point field calibration can
be performed with the hand-held
HM70 meter.
Versatile outputs
The HMT330 can have up to three
analog outputs. Galvanic isolation of
supply power and analog outputs is
also available. For digital
communication, the RS-232, RS-485 or
relay outputs can be used.
A two-point calibration can be
performed with the HMK15 salt bath
calibrator in a controlled environment.
The transmitter can be sent to Vaisala
for recalibration. Accredited
calibrations and maintenance
contracts are also available.

versatile instrument for applications
where a small remote probe is needed.
Flexible installation
possibilities
For installing the probe in ducts,
channels, and through walls, an
installation kit consisting of an
aluminum flange, lead-through piece
and steel support bar is available.
The probe cable is flexible and available
in 2, 5 and 10-meter lengths.
In outdoor environments, the
DTR502B solar radiation shield
provides protection for the probe. The
shield can be installed on a pole, beam
or flat surface.
For moderate humidities and
temperatures
The HMT333 is typically used in
demanding HVAC applications such as
cleanrooms, pharmaceutical processes
and greenhouses.
For environments with continous high
humidity, the HMT337 with a warmed,
vapor-tight, stainless steel probe is
recommended instead of the HMT333.

The HMT337 is the transmitter for the most demanding process and meteorological
measurements.
The Vaisala HUMICAP® Humidity and
Temperature Transmitter HMT337 is
delivered in three configurations:
• Basic: non-warmed probe for
moderate humidities
• With warmed probe: for nearcondensing conditions, dewpoint
measurement
• With warmed probe and additional
temperature sensor: for nearcondensing conditions, relative
humidity measurement
True humidity readings in
condensing conditions
Vaisala’s unique warmed probe head
provides fast and reliable measurement
in environments where humidity is
near saturation. The heating helps the
sensor to recover very fast from
condensation.
As the probe head is warmed, the
humidity level inside the head stays
below the ambient level. With accurate
temperature measurement, the
ambient dewpoint can be calculated
precisely.
Technical Data

If the relative humidity value is needed,

compensation for calculating the
relative humidity and other humidity
parameters.

The HMT338 is ideal for installations in pressurized processes where the probe needs to be
removed while the process is running.
The Vaisala HUMICAP® Humidity and
Temperature Transmitter HMT338 is
designed for pressurized processes.
Insert or remove probe while
the process is running
With “hot tapping”, the probe is
inserted directly into the process while
it is running, without exposing the
need for venting or lowering the
process pressure.
The probe head is screwed into a ball
valve assembly that has been fixed to
the process pipe or wall. The adjustable
hex nut is hand-tightened to
temporarily hold the probe in the ‘up’
position. Then the ball valve is opened,
exposing the probe to the process, and
the probe is pushed to the proper
depth in the ‘down’ position. The hex
nut is tightened with a wrench to lock
the probe in place. Hot tapping is
possible in pressures up to 10 bar.
Graphical measurement trend
and history display
From the display, the user can easily
monitor measurement stabilization
and process trends. Measurement
history with minimum and maximum
values is available for up to 1 year.
