User’s Manual CP-UM-5304
OVERVIEW
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
™
) is used for
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.
Features
•
The temperature and humidity can be measured precisely in a
wide range.
•
The environment-proof is excellent.
•
The long-term stability is excellent.
•
The responsibility and reproducibility are excellent.
•
The probe is separated from the amplifier to achieve a com-
pact design. This allows measurement in a narrow space and
mounting on a small device.
•
As an optional filter is attached to the probe, the protection
structure of the probe is improved to the IP54 dust-proof and
splash-proof structure.
•
This sensor is applicable to the CE marking.
