Pyrometer with sighting window cleanliness monitor

摘要

Coke guide and coke oven infrared pyrometer degrading is minimized to continuously permit better accuracy and reliability in hostile environment of coke mass and heat, dust and/or dirt present in many coke plant areas. These benefits are obtained using production-worthy pyrometer equipment having a purged pyrometer with any of three window cleanliness monitors to determine errors and automatically correcting for same through self-calibration.
