Plugged Chute Detector

The Drexelbrook Plugged Chute Detector reliably detects the presence or absence of material flowing through chutes. 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.). 
Plugged Chute Detector
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.

Due to the rugged sensor design this point level switch is ideal for coal, wood chips, ores and powders. As it is flush mounted through a chute wall, nothing protrudes into the chute to interfere with or obstruct material flow.

This point level switch automatically recognizes and ignores coatings to prevent false alarms. The universal power supply automatically detects and adjusts to the input power source.

Unlike many technologies this point level switch for plugged chute detection allows electronics to be remote mounted to a convenient or safe location. 

The reliable detection of plugged chutes will keep your plant running smoothly and virtually eliminates spills occuring due to plugged conditions.

    • Plugged Chute Detection for Granular Materials

      Detecting plugs in granular material conveying chutes is difficult due to the heavy, abrasive materials and dusty, coating nature of the environment.

    • Level Measurement Solutions for High Density Stock

      The change in density of washed or bleached pulp stock results in inaccurate level measurement. Slow response time to level changes cause pump motors to oscillate. Drexelbrook DR7000 offers a solution.

    • Wallboard Drywall Industry Gypsum Feed Bin

      Measuring granular materials in a chute is an extreme environment for any sensing element. Gypsum rock is abrasive and heavy, causing insertion type sensors to quickly wear, bend, or completely shear off.
