Humidity Sensor
Temperature/Humidity Sensor
ES2-HB ES2-THB
Detect Humidity within an Accuracy of ±3%
in a Compact Body. Controller Set Provides
Superior Humidity Control and Temperature/
Humidity Control.
• Employs high-polymer-resistive Sensor with superior durability.
• Compact and lightweight.
• Measurement ranges of 20% to 95% for humidity and 0 to 55 C
for temperature.

Model
Humidity Sensor Module (See note.) ES2-M
Note:
This is a replacement item. One Module is provided with the
ES2-HB/-THB. Always attach the Humidity Sensor Module
when using the ES2-HB/-THB. Approximately 7 VDC will be
output for the humidity output if the Module is not attached or is
incompletely attached.
Note: 1.
The maximum ripple voltage of 2% p-p max.
The recommended power supply is the OMRON S82K.
2.
ES2-THB only.
3.
Do not use or store the Sensor for an extended period at a
humidity of 90% or more.
4.
Pt100 (JIS C 1604-1989) is used for the measuring
elements. Set
Pt100
for input sensor type of the
Temperature Controller.
Dimensions
Note:
All units are in millimeters unless otherwise indicated.
