HMT300TMK Turbine Mounting Kit for Power
Turbine Intake Air Measurement
The Vaisala HUMICAP
®
Turbine
Mounting Kit HMT300TMK is
developed to monitor the air intake of
gas and liquid fueled power turbines.
It is ideal for measuring in water
vapor injection applications because

the sensor has been optimized for
high humidity environments by
utilizing a patented, warmed probe.
Water vapor is added to the intake of
the turbine to increase the mass ow
which in turn increases compression
and electrical power output.
Low maintenance
Power turbines also require exact
water vapor injection in the chamber
to reduce pollutant emissions.
Vaisala’s warmed probe technology
is ideal because of its reliability in
the eld. In fact, the only suggested
scheduled maintenance is annual
calibration.
Patented, warmed probe
prevents condensation
The HMT300TMK with the HMT337
installed, provides fast and reliable
dewpoint measurement especially
under high humidity conditions
where dew would normally form on
the humidity sensor and thereby
Features/Benefits
▪
Designed for high humidity
applications
▪
Measurement range:
-40 ... +100°C
▪
Patented, warmed probe
▪
Incorporates Vaisala HUMICAP®
Sensor for excellent accuracy
and long-term stability and
resistance to dust and most
chemicals
▪
Low maintenance need
▪

protection from rain and
direct sunlight
▪
NIST traceable
(certificate included)
cause errors in measurement. The
patented warmed probe prevents
condensation from forming on the
sensor.
Protective enclosure
The HMT300TMK includes a white,
painted aluminum enclosure with
an installation kit for the probe. The
HMT337 Humidity and Temperature
Transmitter is installed in the
aluminum enclosure at the factory.
The instrument can be equipped to
be powered with either 24 VDC/VAC
or with an internal 110/230 volt power
supply unit.
The outer cover protects the
transmitter from direct sun light and
rain. The installation kit protects the
probe from outer water splashes,
keeps the sensor dry, and prevents
any parts that could vibrate loose
from entering the turbine.
The HMT300TMK can be ordered
separately for installation with the
customer’s existing HMT337.
HUMICAP® performance
The HMT330 Series Transmitters are
tted with the latest generation of
the HUMICAP
®
, the polymer sensor
known for its accuracy, reliability and
long-term stability. The sensor has a
high tolerance for particulate abrasion
and chemical contamination.
Vaisala HUMICAP®
Humidity and Temperature
Transmitter HMT337
The HMT337 is intended for
demanding industrial humidity
measurement applications with a
risk of condensation. The stainless
steel probe is mechanically durable
and preferred for most industrial
applications.
