Fluke® Process Instruments Expands Line of Endurance® Series High-temperature Ratio Pyrometers

SANTA CRUZ, Calif., February 6, 2017

Fluke® Process Instruments announced the expansion of the Endurance® Series line of high-temperature ratio infrared pyrometers to include three new single-color models and one new two-color model with extended temperature ranges and enhanced optical resolution characteristics. These best-in-class pyrometers meet the demands of harsh industrial environments, including primary and secondary metals manufacturing, carbon processing, silicon production, and now foundries and welding, as well as rubber and thick plastics.

Handling a wider temperature range of 50˚C (122˚F) to 3,200˚C (5800˚F) with superior optical resolution (up to 300:1), these rugged and flexible instruments enable continuous visual process monitoring. Built to tolerate the harshest environments, the sensors feature stainless steel IP65 (NEMA 4) housing able to withstand ambient temperatures up to 65 ˚C (149 ˚F) or up to 315 ˚C (600 ˚F) using cooling accessories, as well as galvanically isolated inputs/outputs.

The Endurance Series pyrometers are remarkably versatile and easy to install – a robust solution for manufacturers looking to reduce reject rates, improve product quality and uniformity, maximize throughput, and minimize 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 (Ethernet, Profinet and RS-485). An intuitive backlit rear-panel with tactile feedback simplifies navigation. 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, sighting and focus options are available for different mounting distance and sighting needs. For example, on-board camera video sighting via Ethernet ensures the sensor is always sighted properly for remote and control room viewing. On-board laser sighting can be used to verify process alignment for local viewing when the sensor is located in a hard-to-reach area. On-board light-emitting diode (LED) sighting makes it easy to view the actual spot size projected on the target. A dirty lens alarm helps avoid unneeded periodic lens cleaning checks. All Endurance Series pyrometers are offered with a best-in-class four-year warranty. For more information, please visit
