Humidity Sensor
ES2-HB
Temperature/Humidity Sensor
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.
Ordering Information
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.
Specifications
Note: 1. The maximum ripple voltage of 2% p-p max.
The recommended power supply is the OMRON S8JX or
S8VS.
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.
ES2-M Humidity Sensor Module
Note: Firmly insert the connector all the way in when mounting the
ES2-M to the Sensor.
