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.
