Temperature / Humidity Sensor
HTY79X3 / HY79X3
General
Insertion dewpoint temperature / humidity sensor
HTY79X3 series uses a Pt100 platinum film temperature
sensing element and a polymer capacitive film humidity
sensing element (FP3 specially developed by Yamatake)
which ensures highly accurate and reliable tempera-
ture/humidity sensing. It is designed to be installed in
return air ducts of commercial buildings, in return air
chambers of air handling units or in ventilated shield for
meteorological instruments. HY79X3 series for sensing
only dewpoint temperature without separate temperature
sensor is also available.
Features
1) Wide sensing range
2) Excellent long term stability
3) Highly resistant to environment
4) Quick response and high repeatability.
5) Easy to install in a duct (bracket prepared)
6) Splash-proof housing (IP54)
