Insertion Temperature/Humidity Sensor
General
Insertion temperature/humidity sensor HTY78X3 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 temperature/humidity sens-
ing. It is designed to be installed in return air ducts of
commercial buildings, in return air chambers of air han-
dling units or in ventilated shield for meteorological in-
struments. TY78X3 series for sensing temperature only
and HY78X3 series for sensing humidity only are 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)
7) No need of maintenance for the head of TY series
(splash-proof without filter)
