Ordering Information

Refer to the Safety Precautions on page 6. Specification (measuring temperature range) Model 0 to 400°C ES1C-A40 Do not use the ES1C in locations subject to rapid changes in ambient temperature. Use a heat shield to suppress temperature changes if the ES1C is used in a location that is subject to rapid changes in ambient temperature due to radiating heat or hot air.

Characteristics of Infrared Thermosensors 1. Principles of Infrared Thermosensors The ES1C uses thermopile light-receiving elements to receive the specific wavelengths (8 to 14 μm) in the infrared range ra- diated from the measurement range of the measurement ob- ject, converts the received light into an output signal in the internal circuits, and outputs a current that corresponds to the measured temperature. 2. Measurement Error due to Emissivity The ES1C outputs a current of 4 to 20 mA for measurement object temperatures of 0 to 400°C at a emissivity of 0.95. If the emissivity of the measurement object is less than 0.9, the ef- fects of the ambient temperature will cause measurement er- ror. Glossy metal surfaces gener ally have an extremely low emissivity, and so operation is easily affected by the ambient temperature, and it is difficult to measure the temperature of the measurement object. (Refer to the emissivities that are given on page 5.) In an application like this, select a location with a high emissiv- ity, or use Black spray or Black tape as necessary. Setting and Adjusting the Connected Device This section describes an example of making settings and adju stments when a Digital Temperature Controller and Digital Panel Meter are connected. 1. Mounting

  • Select a location with a high emissivity for the object to be measured. If required, use Black spray or Black tape.
  • Secure the Thermosensor with the enclosed lock nuts. Use a tightening torque of 20 N·m max.
  • Mount the Thermosensor so that it is perpendicular to the object to be measured.
  • Mount the Thermosensor in a location that is not subject to ambient temperatures above 70°C, to direct hot air, etc. 2. Setting the Connected Device Make the settings so that 0.0 to 400.0 °C is displayed for an output of 4 to 20 mA for the ES1C. * For details, refer to the User’s Manual for the connected device. 3. Adjusting the Connected Device Error may occur due to the emissivity of the measurement en- vironment or measurement object. There are two easy meth- ods that can be used to adjust the error: simple shifting and two-point shifting, as described in the following section.
  • Adjustment Example for the E5@N-L (Analog Input) * E5@N Series have been discontinued at the end of March 2017. A Shift Method 1. Measuring the Temperature of the Measurement Object Use the thermometer (B) to measure the actual tempera- ture when using the measurement object (C). 2. Shifting the Display Value of the Connected Device Adjust the settings of the connected device after checking the following value: Temperature B (thermometer) − Temperature A (connect- ed device) If temperature B minus temper ature A is 10.0, adjust the settings so that measuremen t value of the connected de- vice is +10.0.
  • Scaling upper limit = 4,000 to 4,100
  • Scaling lower limit = 0 to 100 (The setting for the decimal point position is 1, and so the scaling set value will be increased by 100 for a displayed value of +10.0.) Thermopile Internal circuit Measurement range Output signal (4 to 20 mA) Measurement object E5@N-@L Digital Temperature Controller (Analog Input) K3GN-ND@ Digital Panel Meter (DC Input) Input type 0 (4 to 20 mA) Input type Analog Scaling upper limit 4,000 Analog range scaling input value 1 4 to 20 4.00 Scaling lower limit 0 Scaling display value 1 scaling input value 2 20.00 Decimal point position 1 Scaling display value 2 4,000 Decimal point position 0000.0 Measurement object (C) Thermometer (B) Power supply (D) Connected device (A) ES1C Setup for Adjustment Before shift After shift +10.0 Value indicated by connected device (A) Value indicated after shift (e.g., 100.0) Value indicated before shift (e.g., 90.0) Measurement object temperature (e.g., 100°C) (°C) (°C) Temperature indicated by thermometer (B)
  1. Measuring the Temperature of the Measurement Object Set the temperature of the measurement object to room temperature and to the temperature during operation, and check the values indicated by the connected device (A) and the temperatures of the measurement object (B). 2. Shifting the Indicated Value Use the following formula to calculate the upper limit and lower limit of input scaling after the shift from the values Y1 and Y2 indicated by the connected device and tempera- tures X1 and X2 of the measurement object. (1) Scaling upper limit after shift (°C) (2) Scaling lower limit after shift (°C) Change the values to the scaling upper and lower limits from the result considering th e decimal point position. For example, if the scaling upper limit after shift is 487.5 ( °C) and the scaling lower limit after shift is −12.5 (°C), the dec- imal point position of the connected device will be set to the first decimal position, and so the scaling upper limit will be set to 4,875 and the scaling lower limit to −125.
  • Adjustment Example for the K3GN A Shift Method 1. Measuring the Temperature of the Measurement Object Use a thermometer (B) to measure the actual temperature when using the measurement object (C). 2. Shifting the Display Value Adjust the settings of the connected device after checking the following value: Temperature B (thermometer) − Temperature A (connect- ed device) If temperature B minus temperat ure A is 10.0, adjust the settings so that measurement value of the connected de- vice is +10.0.  Scaling display value 1 = 0 to 100  Scaling display value 2 = 4,000 to 4,100 (The setting for the decimal point position is 0000.0, and so the scaling set value will be increased by 100 for a dis- played value of +10.0.) B Two-point Shift Use the teaching function of the K3GN to make adjustments using the ES1C's actual analog input value and the actual tem- perature. Set one of the two teaching points to room tempera- ture and the other to the actual temperature of the measurement object during operation. 1. Move the K3GN to the initial setting level. 2. Set the temperature of the object to be measured to room temperature and set scaling input value 1 using teaching. Next, set the temperature (B) of the thermometer to scal- ing display value 1. (Point A in the following figure. The decimal point position for the K3GN is set to the first deci- mal position, and so set 250 for 25.0°C.) 3. Next, set the measurement object to the actual operating temperature and set scaling input value 2 and scaling dis- play value 2 in step 2. (A value of 1,000 is set to specify 100.0°C for point B in the following graph.)

Note: Operation will be easily affected by the ambient temperature if the emissivity of the measurement object is lower than 0.9. Glossy metal surfaces generally have an extremely low emissivity, and it is difficult to measure the temperature of the measurement object. Use Black spray or Black tape.

(4) Attach a surge protector or noise filter on nearby noise- generating devices (in particular, motors, transformers, solenoids, magnetic coils, or devices that have an induc- tance component). If a noise fi lter is used on the power supply, check the voltage and current, and attach the noise filter as near as possible to the Product. Allow as much space as possible between the product and devices that generates high frequencies (such as high-frequency welders and high-frequency sewing machines) or surges. (5) Use the product within the rated load and power supply. (6) The current output and power supply are not isolated. Be sure that unwanted currents do no occur with the connect- ed device. (7) Do not measure glossy surfaces. (8) Do not let the Product touch the object to be measured. (9) Do not touch the lens. (10) Do not allow charged objects in the vicinity of the Product. CAUTION A malfunction in the product may occasionally result in property damage to connected equip- ment or devices. To maintain safety in the event of malfunction of the product, take appropriate safety measures, such as install- ing a monitoring device on a separate line. Precautions for Safe Use
