  • Page 9: Introduction

    2 Introduction 2.1 Appropriate Use The IMPAC IGAR 320 pyrometer is a stationary, digital pyrometer for non-contact temperature measurement on metals, ceramics, graphite, semiconductors etc. in the range between 300 and 1300 °C. The pyrometer measures in 2-color mode (ratio principle) in which two adjacent wavelengths are used to calculate the temperature.

  • Page 12: Air Purge

    2.6.3 Air Purge The air purge protects the lens from contamination of dust and moisture. It has to be supplied with dry and oil-free pressurized air and generates an air stream shaped like a cone. 2.6.4 90° Mirror The 90° mirror enables the capture of objects at an angle of 90° to the pyrometer axis.
  • Page 13: Controls And Installation

    3 Controls and Installation 3.1 Electrical Installation The pyrometer is powered by 24 V DC ± 25% (very well stabilized, ripple max. 50 mV). It is important to ensure correct polarity when connecting the device to the power supply. To meet the electromagnetic requirements (EMV), a shielded connecting cable must be used. LumaSense offers connecting cables, which are not part of the standard scope of delivery.
  • Page 14: Connecting The Pyrometer To A Pc

    3.1.2 Connecting the Pyrometer to a PC The pyrometer is equipped with an RS485 serial interface. With the RS485, long transmission distances can be realized and the transmission is, to a large extent, free of problems. The RS485 also allows several pyrometers to be connected in a bus system. If an RS485 connection is not available at the PC, it can be accomplished using the RS485 to USB connector.

    Connection of Additional Units Other instruments like an analog controller or printer can be connected to the display in a series as shown above (total load of resistance max. 500 Ohm). 3.2 Sighting 3.2.1 LED Targeting Light The IGAR 320 is equipped with a LED targeting light to assist with aligning the pyrometer to the measuring object.
  • Page 16: Optics

    3.3 Optics 3.3.1 Spot Sizes The IGAR 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). Increasing or decreasing the measuring distance will change the spot size.
  • Page 17: Settings / Parameter Descriptions

    4 Settings / Parameter Descriptions The pyrometer is equipped with a wide range of settings to adapt optimally to the required measuring conditions for correct temperature measurement. The digital PC interface allows you to exchange data with a PC either by using the supplied InfraWin software or by using the Universal Pyrometer Protocol (UPP) commands with your own communication program (see Chapter 7 for the UPP Data Format commands).
  • Page 18: Temperature Errors Cause By Non-Graybodies

    Note: Emissivity Slope K Settings: 0.600 to 2.000 in steps of 1/1000 (2-color mode). 4.2.1 Temperature Errors Cause by Non-Graybodies A graybody target has emissivity that is the same at each of the two wavelengths used for measurements and is constant throughout the temperature range. The ratio of the emissivities, ε1 / ε2= 1 and stays constant regardless of the target temperature.
  • Page 19: Transmittance Τ

    4.3 Transmittance τ Transmittance is a parameter that can compensate for signal loss due to external windows etc. For example, if the emissivity of the material is 0.6 and the transmittance of an additional window is 0.9, then the product would be 0.54, which is well inside the allowed range. ε...
  • Page 20: Clear Time Settings

    Double Storage Double storage mode comes into effect when selecting one of the reset Mode: intervals. This mode utilizes two memories. With the first memory, the highest measured value is held and is deleted alternately in the time interval set (clear time). The other memory retains the maximum value throughout the next time interval.
  • Page 21: Relative Signal Strength

    4.7 Relative Signal Strength Relative signal strength stands for the product of emissivity, surface coverage, and transmission of the material between object and pyrometer. 4.8 “Dirty Window” Warning The IGAR 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 22: Sub Range

    4.11 Sub Range You have the opportunity to choose a sub range (minimum span 50 °C) within the basic measuring range of the pyrometer. This sub range corresponds to the analog output. Example: Range 300…1300 °C, Sub Range 500…600 °C. The sub range setting also affects the maximum value storage when the Clear Peak Memory is set to AUTO.

If the temperature exceeds that, value plus the hysteresis the contact opens (a hysteresis between 2 and 20°C can be set to avoid oscillating of the switch in the switch point).

    5 Software InfraWin The operating and analyzing InfraWin software is included with delivery of the pyrometer. In addition to allowing you to make parameter adjustments, the InfraWin software also provides temperature indication, data logging, and measurement analysis features. A software description can be found in the program’s help menu. Click on the F1 button after loading InfraWin or click on the ? in the menu bar.

  • Page 27: Maintenance

    6 Maintenance 6.1 Cleaning IGAR 320 window Because there are no moving parts in the IGAR 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 IGAR 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 IGAR 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.

    7 Data Format UPP (Universal Pyrometer Protocol) Software commands can be exchanged directly with the pyrometer through an interface using suitable communication software or by using the Test function located in the Pyrometer Parameters window of the InfraWin software package.
