Omron, ES1B Series

last update: December 19, 2013

• 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.

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.
