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. Ordering Information When your order, specify the temperature range.

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. 1ES1B Specifications Ratings/Characteristics Item ES1B Power supply voltage 12/24 VDC Operating voltage range 90% to 110% of the power supply voltage Current consumption 20 mA max.

The accuracy is given as the change in temperature from any reference temperature of the sensing object. For example, if the reference temperature is 50C, the accuracy at 55C would be 2% PV or 2C, whichever is larger and the accuracy at 60C would be 4% PV or 4C, whichever is larger. 3.
