Ircon has added advanced signal detection and attenuation alarming capabilities to its Modline 5R Infrared Thermometer.

The Modline 5 Series 5R Ratio Sensors are designed for non-contact infrared temperature measurement applications involving harsh industrial environments.

The Ircon Modline 5 Series 5R Ratio Sensors use a dual detector assembly that measures temperature by comparing infrared radiation levels in two wavelength bands (0.85 to 1.05 microns and 1.0 to 1.1 microns).

Temperature readings are based on the ratio of the two signals in these bands.

Because the sensors measure the ratio of radiation intensities at two wavelengths rather than the absolute intensity of radiation at a single wavelength, they are almost immune to error caused by loss of signal.

The sensors can tolerate small targets that do not fill the field of view, as well as partial obstructions from bursts of steam, dust and solid objects in their sight path.

The Modline 5 Series provides a new attenuation alarming capability based on the Raytek signal attenuation measurement algorithm, which allows users to adjust the alarm sensitivity level.

By measuring the attenuation, the sensor can provide a notification alarm when attenuation levels exceed a user-defined setpoint limit.

The Modline 5 attenuation adjustment alarming feature operates independently from the optional dirty window detector, which monitors the sensor window for contamination.

It allows users to monitor any kind of signal attenuation caused by dirty viewports or other external windows.

Attenuation alarm settings are configurable from five to 95 per cent, from either the back panel of the sensing head or from the Ircon Modview program.

When an alarm condition is detected, relay outputs provide notification to external process control instrumentation.

The attenuation adjustment alarming feature lets the user monitor attenuation levels in a graphical format in the Modview program, providing a historical view of the levels.

Attenuation levels are also available through the Modline 5 RS-485 output fed into an external device.

Our mission is to be the leading supplier of infrared, noncontact, industrial temperature measurement instruments in the world.

We strive to develop instruments that improve the productivity, reliability, and efficiency of our customer’s processes and maintenance activities and, ultimately, the quality of their products and services. We use profit as a measure for creating a company where people can develop and use their skills in an exciting, challenging and rewarding environment.

Founded in 1963, Raytek designs, manufactures, markets and services a complete line of infrared, noncontact temperature measurements instruments for industrial, process control and maintenance applications. In addition to our worldwide headquarters in Santa Cruz, Calinfornia USA, European headquarters in Berlin, Germany and our China headquarters in Beijing, China, Raytek has regional offices around the globe and is represented by a worldwide network of authorized distributors.

In 2007, Ircon joined Raytek to offer a complete IR solution to our customers.
