Infrared Thermosensor
ES1B
Achieve Low-cost Measurements with an
Infrared Thermosensor.
The ES1B has an electromotive output as high as that of a
thermocouple, thus connecting directly to the thermocouple input
terminal of the Temperature Controller is possible.
Four temperature ranges are available to cover a wide range of
temperature measurement needs, including those in the food
processing, packaging, molding, and electronics industries.
High-accuracy temperature measurement is ensured by a high-speed
response of 300 ms (for a 63% response) and an indication
reproducibility of ±1% PV.
Unlike thermocouples, the Thermosensor does not deteriorate.
Therefore, stable, real-time temperature control can be maintained.
Refer to Safety Precautions for All Temperature
Controllers.

Note: 1. Either a 12 VDC or 24 VDC power supply
is required for the ES1B.
2. To measure the difference in temperature
between two points, use two isolated
power supplies.
Do not use the Infrared Thermosensor in locations where the ambient temperature changes rapidly.
To use the Infrared Thermosensor in locations subject to rapid changes in temperature due to
radiant heat or movement of hot air, use a heat shield or other method to reduce rapid changes in
temperature as much as possible.

Specifications
Ratings/Characteristics
Note: 1. Based on characteristics of K-type thermocouple and radiation rate of 0.98.
2. The accuracy is given as the change in temperature from any reference temperature of the sensing object. For example, if the reference
temperature is 50°C, the accuracy at 55°C would be ±2% PV or ±2°C, whichever is larger and the accuracy at 60°C would be ±4% PV
or ±4°C, whichever is larger.
Dimensions
Note: All units are in millimeters unless otherwise indicated.
Adjustment Methods
Adjust the Thermosensor as described below before using it.
Adjust the Thermosensor according to the conditions of the sensing object and characteristics of the
Temperature Controller.
