Humidity Sensor
ES2-HB TEemSper2atu-reT/HuHmidBity Sensor
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 55qC
for temperature.
Note: 1. The maximum ripple voltage of 2% p-p max.
Ordering Information
The recommended power supply is the OMRON S82K.
2. ES2-THB only.

4. Pt100 (JIS C 1604-1989) is used for the measuring
elements. Set Pt100 for input sensor type of the
Temperature Controller.
ES2-THB
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.
Dimensions
Note: All units are in millimeters unless otherwise indicated.
