Modline 5 is a durable stand-alone infrared sensor built to serve a wide range of industrial temperature measurement applications. Designed with extensive customer input and engineered with the expertise that comes from over 45 years experience in the business, Modline 5 offers advanced features available with no other infrared thermometer series on the market.

Modline 5 56 Series Sensor Highlights:

  • 2 micron (2.0 - 2.8 or 2.3 - 2.6) and lower temperature (as low as
    50° C  / 122° F) units to serve a wider range of applications
  • Thermo-electrically cooled detector
  • Internal self-calibration feature

Modline 5 Sensor Features:

  • Self-contained, Stand-Alone infrared thermometer -- no remote electronics needed for operation
  • PC software for remote sensor setup, configuration and monitoring included
  • Durable, sealed stainless steel NEMA 4 housing
  • Total System Health Check diagnostics feature verifies that the Modline 5 is working within factory specifications
  • Innovative Match Function allows you to input the process temperature (if known) and automatically adjust emissivity
  • Our optional Dirty Window Detector (DWD) checks the temperature sensor window to determine if there is any build-up
  • A complete line of accessories to help the Modline 5 perform in any temperature sensing application
  • Easy-adjusting optics to focus precisely on target
  • Built-In, thru-the-lens Visual or Laser sighting

System Health Check
The Total System Health Check diagnostics tool lets the user verify that the Modline 5 spot pyrometer is working within factory specifications. By activating this check from the rear panel or remotely via the Digital Panel Meter (DPM) the Total System Health Check verifies that the temperature detector, internal circuitry, and even the output signal are all working with the original factory specifications for the sensor. The Total System Health Check is a great verification tool for preventative maintenance programs, start-up, and application troubleshooting.

Dirty Window Detector (Pat. # 5812270)
Dirt, mist, dust, and other types of build-up can affect the accuracy of any infrared thermometer regardless of measurement wavelength. Traditionally it has been up to the enduser to routinely clean the optics of their sensor to ensure that the accuracy of their measurement signal did not degrade too much. The optional Dirty Window Detector (DWD) can sense build-up on the window of the Modline 5 and provide an alarm output to alert the user. Programmable coarse and fine parameters within the Modline 5 setup menus let the user tune the DWD depending on how severe their process is. The DWD is an important option for those processes that cannot tolerate fluctuations in accuracy or the extremely dirty applications where the user wants an alarm to notify his personnel that the sensing window needs to be cleaned.

Match Function
Probably the most common question with non-contact temperature measurement relates to the emissivity of different materials. Now Ircon has taken away some of the guesswork with the Match Function. The Match Function is a standard feature of the Modline 5 Infrared thermometer. If the user knows the exact process temperature (usually verified with a thermocouple / RTD) then they can program the temperature into the Modline 5 prior to start-up and AUTOMATICALLY adjust the emissivity. Equations within the Modline 5 will calculate the emissivity. It’s just that easy!
