Sensor Heating
General
This function is optionally available only in transmitters with
HUMICAP
®
180C or
HUMICAP
®
180RC
sensor. It should be used only
with the warmed probe.
The sensor heating is recommended for the high humidity
environments where even a small temperature differences can cause
water to condense on the sensor. The sensor heating speeds up the
recovery of the humidity sensor from condensation.
Sensor heating starts-up when the relative humidity of the measuring
environment reaches the RH-value set by a user (RH-limit). The user
can define the RH-sensor heating temperature as well as the duration
of the heating.
After the heating cycle the humidity conditions are checked and new
sensor heating is performed if the predefined conditions are reached
again.
NOTE
During the sensor heating the outputs are locked to the values
measured before the heating cycle.
NOTE
The maximum operation voltage for device with sensor heating is 24
VDC.
Setting Humidity Sensor Heating
When HMT310 leaves the factory the sensor heating follows the
factory default values. You can enable or disable the function, change
the RH limit and define the heating temperature and duration of the
heating period.
Sensor Heating ON/OFF
Enables or disables the sensor heating.
