    2 Introduction 2.1 Appropriate Use The IMPAC ISR 320 pyrometer is a stationary, digital pyrometer for non-contact temperature measurement on metals, ceramics, graphite, semiconductors etc. in the range between 700 and 2500 °C. The pyrometer measures in 2-color mode (ratio principle) in which two adjacent wavelengths are used to calculate the temperature.

  • Page 15: Sighting

    3.2.1 LED Targeting Light The ISR 320 is equipped with a LED targeting light to assist with aligning the pyrometer to the measuring object. The LED spot marks the center of the measuring spot on the target. The diameter does not correspond to the spot size. The smallest diameter of the LED spot approximately indicates the measuring distance.

  • Page 16: Optics

    3.3.1 Spot Sizes The ISR 320 has fixed optics for 300 mm or 800 mm measuring distance. The table of spot sizes in relation to measuring distance shows examples of the pyrometer’s spot size M [mm] in relation to the measuring distance a [mm] (min. 90% of the radiation intensity).

  • Page 17: Settings / Parameter Descriptions

    The K-factor can then be adjusted until the pyrometer shows the same temperature value. The ISR 320 is factory calibrated for graybody targets that exhibit equal changes in emissivity within its two spectral bands. Note: Emissivity Slope K Settings: 0.800 to 1.250 in steps of 1/1000 (2-color mode).

  • Page 18: Temperature Errors Cause By Non-Graybodies

    1%. The errors can get quite large as temperatures increase. This error can be much larger than a 1-color IR pyrometer would produce for 1% emissivity change. Therefore, it is important to select the proper mode (2-color vs. 1-color) on the ISR 320 to measure a specific material.

  • Page 19: Transmittance Τ

    The response time is set using the InfraWin software or by using the UPP Data Format commands. When the setting is set to min., the ISR 320 operates using a time constant of 10 ms. The response time can be extended to 0.01 s; 0.05 s; 0.25 s; 1 s; 3 s; 10 s.

    (controller, PLC, etc.). If 4 to 20 mA is set, the analog output gives 4mA for temperatures below lower range limit. Note: Settings for Analog Output : 0 to 20mA or 4 to 20mA ISR 320 Manual Settings / parameter descriptions • 20...

    4.8 “Dirty Window” Warning The ISR 320 pyrometers are equipped with a warning level “dirty window” monitoring system. A correct temperature measurement might be impossible if the ratio pyrometer is working at a too low signal level.

  • Page 27: Maintenance

    6 Maintenance 6.1 Cleaning ISR 320 Window Because there are no moving parts in the ISR 320, the only regular maintenance required is a periodic inspection of the front window for build-up of foreign particles, which, in time, can influence the energy received by the instrument. The ISR 320 has a “Dirty Window” warning alarm feature that can measure the current window/optical path transmission and provide a contact closure alert when the window transmission falls below the user set point.
  • Page 28 • Spot Sizes: Ensure the ISR 320 is using a proper focused distance and takes into account the spot size in relation to measuring distance. In the 1-color (mono) mode, the pyrometer can measure objects at any distance. However, the object has to be bigger than or at least as big as the spot size of the pyrometer in the measuring distance.
