Infrared Thermosensor ES1B CSM_ES1B_DS_E_3_1 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.
