Product Announcement from Arjay Engineering Ltd.


Plugged Chute Detector-Image

Over 40 years of Arjay's field proven HF capacitance technology has been applied to the 2852-PCD plugged chute detectors. The flush mount sensor continuously monitors the change from a normal material chute condition to a plugged condition.

  • capacitance technology responds to any material type
  • no moving parts
  • remote alarm unit mounts safely away from pipe
  • no intrusion into chute or hopper

The 2852-PCD sensor monitors the capacitance field in front of the sensor plate. The sensing plate forms part of the chute or hopper wall to sense the product within. The increased presence of product in front of the sensor due to a plugging condition increases the capacitance field and initiates an alarm.

The sensing plates are embedded into a polyethylene plate which provides monitoring without any intrusion into the product flow.

Features & Benefits:

  • flush mount sensor forms part of the chute wall
  • adjustable time delay and sensitivity to eliminate nuisance alarms
  • remote electronics via standard twisted pair
  • available with Intrinsic Safety Barrier for Hazardous Locations
  • high erosion resistant polyethylene resists wear
  • capacitance technology responds to all types of bulk materials
  • non-intrusive sensor design does not restrict product movement
