The Vaisala HUMICAP
®
Humidity and Temperature
Transmitter HMT337 is delivered in one of three
configurations:
• Basic,withanon-warmedprobeformoderatehumidity
• Withawarmedprobe,fornear-condensingconditions
and dew point measurement
• Withawarmedprobeandanadditionaltemperature
sensor, for near-condensing conditions and relative
humidity measurement
True Humidity Readings in Condensation
Conditions
Vaisalas 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.
Typical Applications
