2 - 6 K6PM-TH Thermal Condition Monitoring Device User’s Manual (H231)
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 × (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
Precautions for Correct Use
• 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 mea-
surement object and the safety certifications, etc.
