O28 - Optional Temperature Compensation



The sensor measures the temperature of the workpiece being tested by detecting the infrared energy emitted by the surface being tested. The ambient temperature is calculated from the metal surface temperature of the sensor head.


  • Measurement of the temperature of the test piece pointed by the sensor
  • Measurement of the ambient temperature at which the workpiece is tested
  • Compensation of the pressure generated by the temperature of the workpiece being tested on the final pressure measurement
  • Allows you to set a high threshold and a low threshold of temperature above which triggers an alarm signal

Technical characteristics
  • One of the smallest existing infrared sensors with an optical resolution of 22:1
  • Precise temperature measurement without direct contact with the test price
  • Measurement of the ambient temperature at which the part is being tested
  • Robust and usable without a cooling system up to 180°C ambient temperature (ambient temperature -20°C ... 180°C)
  • Uses an RS232 interface to connect to the instrument
  • Can be used for metal and non-metallic surfaces
  • Can operate with relative humidity ranging from 10 to 95% (non-condensing)
  • Weight: 40 g the sensor head, 420 g the sensor body (the electronics)
  • Can withstand 3 G of vibration (11-200 Hz) per axis
  • Can withstand a shock of 50 G (11ms) per axis
  • The head withstands a pressure of 8 bar


The external temperature sensor is connected to the COM2 serial port of the instrument. The connection completely occupies the port and it is not possible to use double cables to connect, for example, printers or barcode readers.

Both the ambient temperature and the temperature pointed by the sensor are read cyclically with a frequency of one second.
