A better alternative is the Drexelbrook Intellipoint RF Admittance Plugged Chute Detector. Its design allows for the reliable detection of a plugged chute, reducing costly downtime and material spill over.
The Drexelbrook plugged chute detector, also known as a blocked chute switch, reliably detects the presence or absence of bulk solids material flowing through chutes in an economical way without sacrificing flow speed. If process material stops flowing due to a plugged condition, the flush mounted capacitance sensing element will alarm, allowing further action to occur (alerting an operator, shutting down a conveyor belt, etc.). The Cote shield circuitry ignores even heavy coatings, and the flush mounted sensing element does not interfere with material flow. There are no moving parts to wear or jam, and thus, it requires virtually no maintenance. In fact, the Intellipoint Mean Time To Failure (MTTF) is calculated to more than 110 years!
There are no regulatory requirements with the adoption of the Intellipoint, and system electronics can be mounted remotely to eliminate vibration concerns. Due to the rugged sensor design this point level switch is ideal for coal, wood chips, ores and powders. This point level switch automatically recognizes and ignores coatings to prevent false alarms and, as it is flush mounted through a chute wall, nothing protrudes into the chute to interfere with or obstruct material flow.
Choosing the Intellipoint provides reliable detection of plugged chutes that will keep your plant running smoothly and virtually eliminates spills occurring due to plugged conditions.
