Endurance fiber-optic pyrometers allow measurement of targets that would otherwise be inaccessible because of space constraints or harsh environments. Separated by a flexible fiber-optic cable, the optical head may be positioned near the target with the rugged electronics housing installed remotely in a convenient location. Fiber-optic sensors are completely non-conductive and offer improved immunity to RFI and EMI interference.
Endurance companion software allows you to archive your process temperatures for data analysis and sensor setup.
Endurance meets the requirements of Digital Industry. It is designed to measure product temperature in the harshest of environments and communicate the results back to control system or monitoring stations. This stainless steel housed pyrometer can be specified with the widest range of communication interfaces from rugged analogue isolated input/output through to fast LAN/Ethernet and RS485.
