HMT330 Series Humidity and Temperature
Transmitters for Industrial Applications
Features/Benefits
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
is important.
Vaisala HUMICAP®
performance
The HMT330 series incorporates
Vaisala’s 30 years of experience in
industrial humidity measurement.
An updated, even more stable and
chemical resistant HUMICAP® sensor
is available, next to the proven reliable
and accurate sensor.
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.

Graphical display of history
and measurement trends
The HMT330 can be ordered with a
large numerical and graphical display,
which allows the user to clearly monitor
operational data, measurement trends
and 1-year measurement history.
The optional data logger with real-time
clock makes it possible to generate
over four years of measured history,
and zoom in on any desired time or
time frame. The battery backup of the
clock guarantees a reliable logging of
measured data.
• Six models for demanding industrial
applications
• Full 0 ... 100 % RH measurement,
temperature range up to +180 °C
(+356 °F) (depending on model)
• Pressure tolerance up to 100 bar
(depending on model)
• Next generation Vaisala HUMICAP®
Sensor for excellent accuracy and
stability
• Graphical display of measurement
trends and over four-year history
• Multilingual user interface
• Excellent performance in harsh
chemical concentrations
• Corrosion resistant IP65 housing
• NIST traceable (certificate included)
• Analog outputs, WLAN/LAN
connect the service port of the HMT330
to a PC.
Many ways to install and
versatile outputs
Mains and DC power options, and
several mounting accessories make the
instrument easy to install.
The HMT330 can have up to three
analog outputs. Isolated galvanic power
supply and analog outputs are also
available. For serial interface the USB
connection, RS232 and RS485 can be
used.
The display alarm allows tracking of
any measured parameter, with a freely
configurable low and high limit.
Data collection and (wireless)
transfer to PC
The recorded measurement data can be
viewed on the 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-RJ45 cable makes it easy to
The display shows measurement trends, real
time data and over four years of history.

Flexible calibration
The HMT330 instruments are calibrated
at six humidity points at the factory.
A quick, one-point field calibration can
be performed with the hand-held 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.
The Vaisala HUMICAP® Hand-Held Humidity
and Temperature Meter HM70 is ideal for
field checking HMT330 transmitters.

Outputs and power supply
options for every need
The output options include three analog
outputs, RS-232, RS-485, and alarm
relays.
The voltage supply range is from 10 to
35 VDC. With an additional module,
the transmitter can be connected to
all universal mains AC supplies. The
input/output cable can be fed through
the back of the transmitter, which is a
useful feature, especially for installations
in cleanrooms.
