1.3 Explosion Proof Enclosure
The sensors are packaged in a cast metal explosion proof enclosure. The enclosure is fitted with a threaded
cover that has a glass lens window. Magnetic program switches located behind the transmitter module face
plate are activated through the lens window via a handheld magnetic programming tool allowing non-intrusive
operator interface with the sensor. Calibration can be accomplished without removing the cover or
declassifying the area. Electrical classification is Class I; Groups B, C, D; Division 1.
