Infrared Thermosensor ES1B CSM_ES1B_DS_E_3_3 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. ■ List of Models Appearance and sensing characteristic 2 mm 20 mm 40 mm Specification (temperature range) 10 to 70°C 60 mm Model ES1B 60 to 120°C 115 to 165°C 140 to 260°C 2 dia. 20 dia. 40 dia. 60 dia. Application Examples Temperature Control of Ironing Portion Film Temperature Measurement of Sheet Molding Machines and Resin Extrusion Machines DC power supply Vertically heating rolls Resin 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.

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. 3.
