Glass Level Detector

Performing Multiple Tasks – Precisely!

The Global Glass GTI Auto-Level Glass Level Detector combines state-of-the-art computer technology with a proven method of non-contact glass level measurement to assure precise continuous monitoring of the glass surface to +/-0.001″ (0.025mm).

Since Global Glass Equipment Engineering first introduced the detector in the 1980s, it has been significantly refined to provide easier installation, operation and maintenance while adding features to improve accuracy and enhanced control. In essence, it’s a detector, a recorder, a controller – and possibly more.

The GTI Auto-Level samples glass level on a programmable interval of 30 seconds or more and waits between intervals with the sensing probe retracted above the glass level, also at a programmable distance. This innovation provides more accurate glass level detection and virtually eliminates the possibility of the sensing probe touching the glass surface, even when there is a sudden change in glass level or variation in furnace pressure.
