Refractory Lining Thickness Meter

The furnace lining thickness gauge measures the thickness by calculating the time difference or intensity changes of reflected signals, utilizing the propagation characteristics of ultrasonic or electromagnetic waves in the lining material. It is used to monitor the wear of industrial furnace linings and conduct regular inspections in industries such as metallurgy, glass, and cement to prevent production interruptions caused by lining damage.
Selection
When selecting, consider the compatibility between the furnace lining material and the temperature range to choose the appropriate probe type, using heat-resistant types for high-temperature environments; determine whether to use a portable or fixed type based on the furnace structure; the measurement accuracy must meet safety margin requirements; check the instrument's protection rating to ensure it is suitable for on-site dust conditions; confirm whether the data storage and transmission functions are compatible with the existing management system.
