Reference Relationship between the Measurement Surface and Measured Distance In order to measure the temperature more correctly, as shown in the figure below, install the infrared thermal sensor at a distance where the measurement object can be captured as a large image, as far as possible at the center of the field of view. The relationship between the sensor visual field width and the distance from the infrared thermal sensor to the measurement object is as shown below. Sensor visual field width = 2 Ч (Distance from infrared thermal sensor up to the measurement object) Example:
When the distance from the infrared thermal sensor up to the measurement object is 100 mm Sensor visual field width: 200 mm Front view Side view Sensor visual field width: 200 mm Measurement object Sensor visual field width: 200 mm Viewing angle Field of view per pixel: 6.25 mm angle 90° 100 mm Top view Distance from sensor up to the measurement object Sensor visual field width: 200 mm Measurement object Viewing angle 100 mm 90° Distance from sensor up to the measurement object • Measurement objects: Metals and transparent resin materials cannot be properly measured.
• Set the distance up to the measurement object in view of the occurrence voltage of the measurement object and the safety certifications, etc. 17 使Pr用ec上auのtio注n意s f or Correct Use
