Detect the presence of glass in a high-temperature, vacuum chamber during chemical vapor deposition process.
Objective: Detect the presence of solar glass while in a high-temperature, high-vacuum environment.
Solution 1:
A diffuse photoelectric laser can be mounted to shoot through a site glass or quartz viewport to detect the glass. A background suppression laser sensor, like
BOS 18M-PSV-LH22-S4, should be used if the far side of the vacuum chamber could false trigger or latch the sensor on.

A high temperature capacitive sensor can be mounted to the top of the vacuum chamber to detect the presence of the glass as it passes. Capacitive sensor
SK-HT250-10-M18-NB-VA/PTFE is capable of operating at temperatures up to 250 °C (482 °F). This sensor requires amplifier
SV-45/30/15-PS and mating cable
SLK-HT.
