Duct Temperature/Humidity Sensor
„ Overview
The duct temperature/humidity sensor (Model
HTY78_5 series) is a highly precise and reliable
sensor using the resistance temperature detector
(Pt100) for the temperature sensor and the
polymer capacitive humidity detector (FP5*) for the
humidity sensor.
With a wide measurement range and excellent
stability, it can be applied to various industrial
applications such as outdoor air measurement as
well as it is used in the ducts, chambers, etc. of
general buildings for air conditioning.
* A sensor element developed by Azbil Corporation
„ Features
• Wide temperature and/or humidity sensing range
with high accuracy
• Excellent long-term stability
• High environmental resistance
• Quick response and high repeatability
• A dedicated bracket is used enabling easy
attachment or detachment of the sensor.
It is easily attached in the ducts or chambers.
• Dust-proof and splash-proof (IP54) housing

▲ Model HTY7805
IMPORTANT • The measuring accuracy of this product
is the value when it is shipped from the
factory.
Even if it is used in normal air, the output
may be shifted depending on the operating
environment.
Periodical inspection is recommended.
• Corrosive gases or organic solvents may
cause a shift in humidity output or damage
the product.
If the sensor is used in an environment
different from the ordinary air, please
contact Azbil Corporation.
