The Vaisala HUMICAP
®
Humidity
and Temperature Transmitter
HMT337 is delivered in one of three
congurations:
r #BTJDOPOXBSNFEQSPCFGPS
moderate humidities
r 8JUIBXBSNFEQSPCFGPSOFBS
condensing conditions and dew
point measurement
r 8JUIBXBSNFEQSPCFBOEBO
additional temperature sensor: for
near-condensing conditions and
relative humidity measurement
True humidity readings
in conditions of
condensation
The Vaisala unique warmed
probe provides fast and reliable
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)
The HMT337 is the ideal transmitter for the most demanding process and
meteorological measurements.
measurement in environments where
humidity is near saturation. The
warming prevents condensation from
forming on the sensor.
As the probe is warmed, the humidity
level inside it stays below the ambient
level. With accurate temperature
measurement, the ambient dewpoint
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.
Many ways to install
A tight installation through a process
wall can be achieved with Swagelok
®
ttings. Meteorological installation
kits for outdoor installations and duct
installation kits are also available.

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 is screwed into a ball
valve assembly that has been xed
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
Features/Benefits
▪
Installed through ball valve
– can be inserted and removed
while the process is running
▪
Adjustable probe depth
▪
Pressure tolerance 40 bar
▪
For temperatures
-70 ... +180 °C (-94 ... +356 °F)
▪
Two probe lengths available
The HMT338 is ideal for installations in pressurized processes where the probe
needs to be removed while the is running.
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 operational data,
measurement trends and one-year
measurement history.
The optional data logger with
real-time clock makes it possible
to generate more than four years
of measured history, and zoom in
on any desired time or time frame.
The battery backup of the real-time
clock guarantees a reliable logging of
measured data.
Vaisala HUMICAP®
The HMT338 incorporates Vaisala’s
more than 30 years of experience in
industrial humidity measurement.
The sensor provides accurate and
reliable measurement and is immune
to particulate contamination and
most chemicals.
