Field-Proven Bulk Solids Level Detector

Don Horne   

The Dynatrol DJ Level Switch operates as a high- mid- or low-level indicator on bulk solids materials.  It provides accurate measurement ranging from low-density flakes and powders, to pellets and heavy granular materials.

Constructed for a long operating life, the Dynatrol DJ Level Detector withstands dusty environments and works well in vessels equipped with vibrators. It requires no adjustments and has no moving parts.  Without gaskets or seals to deteriorate and they are virtually wear-free.  Specialized units are available for temperatures in excess of 500°F.

Operation:  Dynatrol DJ Level Detectors rely on mechanical oscillations to determine if the probe is covered or uncovered.  Signals from the Detector operate a single pole double throw relay within the control unit.  The relay contacts can actuate alarms, indicator lights or process control equipment.

Installation is simple.  All level detectors arrive ready for installation; no field calibration required.  The separate control unit permits easy set up at any convenient location.  The Dynatrol level detector is mounted through a 3/4” half-coupling at the point of desired level detection, eliminating costly flanges, float chamber or fittings.

Approved for Class 1, Groups C & D.  Class II, Groups E, F & G; Class III services.
