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 55qC

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 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.

ES2-M Humidity Sensor Module

Note: Firmly insert the connector all the way in when mounting the

ES2-M to the Sensor.
