Infrared Thermosensor
ES1B
CSM_ES1B_DS_E_3_4
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.

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.
