Warmed Probe PTU307
Temperature difference between the probe and external environment can
cause a risk of condensation on the sensor. A wet probe cannot observe
the actual humidity in the ambient air. If the condensed water is
contaminated, the life span of the probe may shorten and calibration may
change.
PTU307 probe shall be used in applications where condensation can
occur due to high humidity and rapid humidity changes. The warmed
probe is heated continuously so that its temperature is always higher than
that of the environment. This prevents condensation on the probe. The
power consumption of the warmed probe is slightly higher than that of
the other probes.
