The Modline 5 Series 5R Ratio Sensors are designed for non-contact infrared-temperature-measurement applications in harsh industrial environments. These sensors use a dual detector assembly that measures temperature by comparing infrared radiation levels in two wavelength bands (0.85 – 1.05 microns and 1.0 – 1.1 microns). Temperature readings are based on the ratio of the two signals in thse bands. Because this ratio is used rather than the absolute intensity of radiation at a single wavelength, the Modline 5 Series 5R sensors are almost immune to error caused by loss of signal. Small targets that do not fill the field of view and partial obstructions (from bursts of steam, dust and solid objects in their sight path) can be tolerated. — Ircon, Santa Cruz, Calif.
