Fluke Process Instruments announced the expansion of the Endurance series high-temperature ratio infrared pyrometers to include a new, rugged non-contact fiber-optic (FO) measurement system with single and two-colour models. These best-in-class pyrometers meet the demands of harsh industrial environments, including primary and secondary metals manufacturing, primary glass manufacturing and laser welding.

With an expanded temperature range of 250°C to 3200°C and superior optical resolution (up to 100:1), these rugged and flexible fiber-optic instruments enable continuous visual process monitoring. Built to tolerate harsh environments, the sensors feature IP65 (NEMA 4) housing able to withstand ambient temperatures up to 60°C or up to 150°C using cooling accessories, as well as isolated analog inputs/outputs. The fiber-optic sensing head can operate in areas of high ambient temperatures up to 315°C without cooling and in areas of high electro-magnetic fields. The optical cable is made of multiple glass fibers, allowing for a minimal bending radius to ease installations in constricted rooms.

The Endurance series FO pyrometers are remarkably versatile and easy to install – a robust solution for manufacturers looking to reduce reject rates, improve product quality and uniformity, maximise throughput and minimise energy costs. Their broad temperature range and multiple wavelengths cover an entire process with fewer units. The sensors operate with either Power over Ethernet (PoE) or DC power, and interface to various bus systems (LAN/Ethernet, Profinet and RS-485). PC-based Endurance setup and monitoring software simplifies configuration and deployment, and a built-in web server enables archiving of historical data for traceability, process troubleshooting and remote viewing.

Multiple lens and sighting options are available for different mounting distance and sighting needs.
