The HMT330 transmitter family has the solution for demanding industrial
humidity measurements.
Versatile outputs
The Vaisala HUMICAP® Humidity
and Temperature Transmitter
Series HMT330 is designed for
demanding industrial applications
where stable measurement and wide
customization is important.
The HMT330 can have up to three
analog outputs. Isolated galvanic
power supply and analog outputs
are also available. RS-232, RS-485, or
relay outputs can be used for digital
communication.
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 measurement
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.
Flexible calibration
The display shows measurement trends and
history up to one year.
Graphical display of history
and measurement trends
The HMT330 can be ordered with a
large numerical and graphical display
allowing the user to easily monitor
measurement trends and one-year
history.
Data collection and transfer
to PC
The recorded measurement data
can be viewed on the display or
transferred to PC with Microsoft
Windows® software.
Many ways to install
Mains and DC power options, and
several mounting accessories make
the instrument easy to install.
The HMT330 instruments are
calibrated at six humidity points at
the factory.
A quick, one-point field calibration
can be performed with the handheld HM70 meter.
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.

HMT337 Humidity and Temperature Transmitter
for High Humidity Applications
Features/Benefits
• For high-humidity applications in
industry and meteorology
• Warmed probe for superior
performance in condensing
environments
• Small, stainless steel, vapor-tight
remote probe
• For temperatures -70 ... +180 °C
(-94 ... +356 °F)
• Vaisala HUMICAP® Sensor for excellent
accuracy and stability
• High tolerance of chemicals
• Graphical display of measurement
trends and one-year history
• Corrosion resistant IP65 housing
• NIST traceable (certificate included)
The HMT337 is the ideal transmitter for the most demanding process and
meteorological measurements.
True humidity readings in
conditions of condensation
If the relative humidity value is
needed, an additional temperature
sensor head is used. The measured
ambient temperature provides the
compensation for calculating the
relative humidity and other humidity
parameters.
Many ways to install
A tight installation through a process
wall can be achieved with Swagelok®
fittings. Meteorological installation
kits for outdoor installations and
duct installation kits are also
available.
Duct installation kit
Ø 3.2 (0.13)
37.5 (1.48)
Ø 6 (0.24)
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.
Ø 12 (0.47)
The Vaisala unique warmed probe
head provides fast and reliable
measurement in environments
where humidity is near saturation.
The warming prevents condensation
from forming on the sensor.

HMT338 Humidity and Temperature Transmitter
for Pressurized Pipelines
Features/Benefits
• Installed through ball valve
- can be inserted and removed while
the process is running
• Adjustable sensor head depth
• Pressure tolerance 40 bar
• For temperatures -70 ... +180 °C
(-94 ... +356 °F)
• Vaisala HUMICAP® Sensor for excellent
accuracy and stability
• Graphical display of measurement
trends and one-year history
• Corrosion resistant IP65 housing
• Two probe lengths available
• NIST traceable (certificate included)
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 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 to the
process. Then the probe is pushed
down to the appropriate depth. The
hex nut is tightened with a wrench
to lock the probe in its place. Hot
tapping is possible in pressures up to
10 bar.
Graphical display of history
and measurement trends
From the display, the user can easily
monitor measurement stabilization
and process trends. Measurement
history is available with minimum
and maximum values up to one year.
Vaisala HUMICAP®
The HMT338 incorporates Vaisala’ s
