HMT330 Series Humidity and Temperature
Transmitters for Demanding Humidity Measurement
Features/Benefits
The HMT330 transmitter family offers reliable performance for a wide variety of
demanding industrial humidity measurements.
The Vaisala HUMICAP® Humidity
and Temperature Transmitter Series
HMT330 is designed for demanding
industrial applications where
stable measurements and extensive
customization are essential. With
multiple options to choose from, the
instrument can be tailored to meet
the specific needs of each individual
application.
Proven Vaisala HUMICAP®
Performance
The HMT330 series incorporates
Vaisala’s 40 years of experience in
industrial humidity measurement.
The updated fourth-generation
HUMICAP sensor provides accurate
and stable measurement even in
environments with high humidity or
chemical contaminants.
Chemical Purge Minimizes
Effects of Contaminants
In environments with high
concentrations of chemicals and
cleaning agents, the chemical
purge option helps to maintain
measurement accuracy between
calibration intervals.
The chemical purge involves heating
the sensor to remove harmful
chemicals. The function can be
initiated manually or programmed to
occur at set intervals.

Wide Range of Installation
Options
The wide variety of measurement
probes, several installation
accessories, and universal mains
and DC power options make the
instruments easy to install in various
locations and kinds of environment;
walls, poles, pipelines, and ducts,
for example. The input/output cable
can be fed through the back of
the transmitter, which is a useful
feature, especially for cleanroom
installations.
The HMT330 series includes six
models:
•
HMT331 for wall-mounted
applications
•
HMT333 for ducts and tight
spaces
•
HMT334 for high-pressure and
vacuum applications
•
HMT335 for high-temperature
applications
•
HMT337 for high-humidity
applications
•
HMT338 for pressurized pipelines
This device is designed to integrate
seamlessly with the Vaisala viewLinc
CMS, which is a Part 11/Annex 11
compliant software that can be easily
implemented following the GAMP5
guidelines.
Graphical Display of
Measurement Data and
Trends for Convenient
Operation
The HMT330 series features a large
numerical and graphical display with
a multilingual menu and keypad.
It allows users to easily monitor
operational data, measurement
trends, and access measurement
history for the past 12 months.
The optional data logger, with
real-time clock, makes it possible
to generate over four years of
measurement history, and zoom in on
any desired time or time frame.
The display alarm allows any
measured parameter to be tracked,
with freely configurable low and
high limits.
Versatile Outputs and
Data Collection
The HMT330 can support up to three
analog outputs; an isolated galvanic
power supply and relay outputs are
also available.
For serial interface the USB
connection, RS232, and RS485 can
be used.
HMT330 is also capable of applying
the MODBUS communication protocol
and, together with an appropriate
connection option, provides either
MODBUS RTU (RS485) or MODBUS
TCP/IP (Ethernet) communication.
The data logger, with real-time clock
and battery backup, guarantees
reliable logging of measurement data
for over four years. The recorded
The display shows measurement
trends and over four years of real-time
measurement history.
data can be viewed on the local
display or transferred to a PC with
Microsoft Windows® software. The
transmitter can also be connected to
a network with an optional (W)LAN
interface, which enables a (wireless)
Ethernet connection. A USB service
cable makes it easy to connect the
HMT330 to a PC via the service port.
Flexible Calibration
The HMT330 instruments are
calibrated at six humidity points
at the factory and come with a
calibration certificate that meets
all the relevant traceability and
compliance requirements.
A quick, one-point field calibration
can be performed with the handheld HM70 meter. A two-point field
calibration can be performed,
for example, with the HMK15 salt
bath calibrator in a controlled
environment. The transmitter
can also be sent to Vaisala for
recalibration, and accredited
calibrations are available.

HMT333 Humidity and Temperature Transmitter for Ducts and Tight Spaces
The Vaisala HUMICAP®
Humidity and Temperature
Transmitter HMT333 is a
versatile instrument for
applications where a small
remote probe is needed,
for example in demanding
HVAC applications. Its small
thermal mass enables rapid
response to temperature
changes.
Flexible Installation
Typical Applications
The HMT333 transmitter’s
compact probe is designed for
remote applications.
To install the probe in
ducts, channels, and
through walls, an installation kit is available with a stainless
steel flange, lead-through piece, and steel support bar.
The HMT333 has two probe cable options – a flexible
rubber cable that withstands temperatures of up to +80 °C,
and a durable cable that withstands temperatures of up to
+120 °C. Both cable options are available in lengths of 2, 5,
and 10 meters. Additionally, flexible rubber cable (+80 °C) is
available in 20-meter lengths.
For outdoor environments, the DTR502B solar radiation
shield provides protection for the probe. The shield can be
installed on a pole, beam, or flat surface.

True Humidity Readings in Condensation
Conditions
Vaisala’s unique warmed probe provides fast and reliable
measurement in environments where humidity is near
saturation. The heating prevents condensation from
forming on the sensor.
As the probe is heated, the humidity level inside it stays
below the ambient level. With accurate temperature
measurement, the ambient dew point can be calculated
precisely.
If the relative humidity value is needed, an additional
temperature sensor is used. The measured ambient
temperature provides the compensation for calculating
relative humidity and other humidity parameters.
Installation Options
Tight installation through a process wall can be achieved
with Swagelok ® fittings. The optional HMT330MIK
Installation Kit is available for outdoor installations; duct
installation kits are also available.

▪
▪
▪
process lines
environmental chambers
vacuum-drying processes
compressed air lines with refrigerant dryers
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.
Technical Data
Insert or Remove the Probe while the
Process is Running
Accessories
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 is tightened to a ball-valve assembly fixed to
the process pipe or wall. The adjustable hex nut is handtightened to temporarily hold the probe in place. The probe
is then pushed down to the appropriate depth. The hex nut
is then tightened with a wrench to lock the probe in place.
Hot tapping is possible in pressures up to 10 bar.
