Overview

This separate type temperature humidity sensor HTY7843 is a
highly precise and reliable sensor, in which a Pt100 platinum
RTD (JIS C1604 class A) is used for the temperature sensing ele-
ment and a polymer capacitive film humidity sensing element
(Azbil Corporation's development model No. FP3
the humidity detection element. This separate type temperature
humidity sensor provides a wide measuring range and excellent
stability.
Therefore, this sensor can be used for measurement of the outside
air and in various industrial fields, such as insides of air-condi-
tioner ducts and chambers.
