ES1B

Infrared Thermosensor ES1B 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 highspeed 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.

Preparations Refer to the preparations for a one-point input shift. 1. The input value is shifted at two points: near room temperature and near the set point. To do so, first check the temperature C of the sensing object and the temperature A indicated on the Controller at both near room temperature and near the set point. 2. Use the following formulas to calculate the upper-limit temperature input and lower-limit temperature input settings based on the values checked above.

Adjust the temperature of the sensing object in the configuration shown in figure 1 to near the set point. We will assume that the temperature indicated on the thermometer is the actual temperature of the sensing object. 2. Check the temperature C of the sensing object and the temperature A indicated on the Controller and set both the upperlimit and lower-limit temperature input settings to the following value: Temperature C (sensing object) - Temperature A (Controller) 3. Check the temperature C of the sensing object and the temperature A indicated on the Controller again. If they are about the same, then setting the offset has been completed. insh= YH-Y1 ´{(X2-Y2)-(X1-Y1)}+(X1-Y1) Y2-Y1 3. Set both the upper-limit and lower-limit temperature input settings and then check the temperature C of the sensing object and the temperature A indicated on the Controller both near room temperature and near the set point. 4. Although here we have used two points, near room temperature and near the set point, accuracy can be increased even further by using another point within the measurement temperature range other than the set value instead of room temperature.

Here, the set point lower limit, YL, would be 0°C and the set point upper limit, YH, would be 260°C in formulas 1 and 2 . The temperatures of the sensing object are checked next. The offset values can be calculated as shown below when the Controller display Y1 is 40°C for a room temperature X1 of 25°C and when the Controller display Y2 is 105°C for a set point temperature X2 of 110°C Upper-limit Temperature Input Setting insl= 0-40 ´{(110-105)-(25-40)}+(25-40) 105-40 = -27.3 (°C) Lower-limit Temperature Input Setting insh= 260-40 ´{(110-105)-(25-40)}+(25-40) 105-40 = 52.7 (°C) Infrared Thermosensor ES1B 5 Precautions !CAUTION If this product should malfunction and cease to provide correct output, property damage may occur to the equipment or device that is connected to it. To prevent this, provide additional safety measures by also connecting the equipment or devices to a separate alarm system that will warn operators of temperature rises. Precautions for Correct Use 1. The thermocouple output and power supply are not isolated. Make sure that unwanted circuit paths are not formed with the equipment or device that is connected to the product. 2. To prevent inductive noise, wire the product separately from highvoltage sources and power lines carrying large currents. Also avoid parallel wiring or shared wiring paths with power lines. 3. Do not allow the filter to become soiled. Use air blow or use a thin cotton swab to clean the filter. Precautions for Safe Use 1. Use the ES1B only within the ranges specified by its specifications and ratings. 2. Be sure to correctly wire the input sensor leads to the proper positive and negative terminals. 3. Do not use the product in the following locations: • Locations subject to icing or condensation. • Locations subject to excessive shocks or vibration. • Locations subject to dust or corrosive gases. • Locations subject to extreme temperature changes or direct sunlight. • Locations subject to water splashing or oil contact. 1. Installation • Select a place where the emissivity is high for measuring the target. If necessary, use black spray or black tape. • Use the supplied locknuts to fix the ES1B securely in place. Tighten to a torque of 0.5 N·m max. • When measuring a high-temperature object, use a shield or similar protection to prevent the temperature of the ES1B from rising. 2. Connection • Connect to the green output lead wire (+), white output lead wire (-), orange power supply lead wire (+), and shield power supply wire (-). • To measure the temperature difference between two locations, use two isolated power supplies. Power supply (+) ES1B Power supply (−) Output (+) Output (−) ES1B Output (−) Output (+) Power supply (+) Power supply (−) DC power supply Temperature Controller DC power supply ES1B Output (+) Output (−) ES1B Output (−) Output (+) Power supply (+) Power supply (−) DC power supply Temperature Controller 3. Adjustment • The output impedance of the ES1B is 1 to 4 kW. Normally, current leaking to the ES1B from the burnout detection circuit of the temperature controller will offset the measured temperature in a range extending from several degrees to several tens of degrees. When using a controller equipped with an input shift function, use the input shift function to compensate for this offset error in the vicinity of the measuring temperature. For details on this compensation, see Input Shift Method below and the user's manual of the controller being used. • If the length of a lead wire must be extended, use a K thermocouple compensating conductor for the output lead wires (+, -), and standard copper wire for power supply leads (+, -). • Do not bend lead wires repeatedly. 4. Cleaning • Do not use paint thinner or the equivalent for cleaning. Use standard grade alcohol. 6 Infrared Thermosensor ES1B Infrared Thermosensor ES1B 7 Warranty and Application Considerations Warranty and Limitations of Liability WARRANTY OMRON's exclusive warranty is that the products are free from defects in materials and workmanship for a period of one year (or other period if specified) from date of sale by OMRON.
