Chipboard Detection in Dirty Surroundings

The chipboard (particle board) turner from BHT Bau- und Holztechnik Thüringen GmbH requires a detection system that can reliably detect whether a compartment is occupied or not, even in dirty and dusty surroundings.

The solution consists of approximately 30 ultrasonic sensors UB500-30GM-E5-V15, which are installed horizontally between the roller conveyors. The attached sound deflector UVW90-M30 deviates the ultrasound upwards and the sensor detects whether a compartment is occupied or not. Dust and dirt cannot settle on the active sensor, and falls down through a slot in the sound deflector.

Using the ultrasonic sensor with attached sound deflector helps prevent error signals and downtime caused by contamination.
