FurnaceSpection Furnace Inspection System for Continuous Temperature Measurement Inside Furnaces

FurnaceSpection Furnace Inspection System

The FurnaceSpection furnace inspection system is a radiometrically calibrated thermal imaging system that provides real-time continuous temperature measurement inside high-temperature furnaces in refining, metals, and glass production processes. It measures the temperature of product, refractory, and heat transfer surfaces inside natural gas-fired furnaces. The powerful software enables process abnormalities to be quickly identified before they develop into problems, with streaming images, historical trending, digital and analogue outputs. The system can be configured for use with either single or multiple camera configurations.

Key features
