GJ Level Switch

Dynatrol® CL-10GJ Level Detector operates with consistent results on problem applications that have a tendency to bridge or pack. It handles difficult products such as flour, cocoa, sugar, pharmaceutical powders, powdered lime and additional bulk solid materials for high-, intermediate- or low-point level detection. The CL-10GJ is typically used with bulk solids in the density range of 10-15 lbs/ft3.

General Information

Dynatrol® Level Detectors are constructed for a long operating life, require no field adjustments and can be modified for special level detection applications such as:

  • Temperatures up to 750°F
  • Cryogenic temperatures
  • Simple installation. Installation is made in the tank wall through a 3/4-inch, half-coupling at the point of desired level detection.
  • With the CL-10GJ, reliable operation can be achieved in problem applications where other types of controls may fail to operate at all. Let Automation Products, Inc. provide a worry‐free solution for you today!

Principle of Operation

The Dynatrol® GJ Level Detector consists of a paddle-style probe which is installed through the wall of the bin or duct at the point of desired level detection. When the probe is uncovered the paddle is free to vibrate and produce an output signal. This signal operates a relay indicating the paddle is uncovered and a low level exists. When the paddle is covered a dampening of the oscillation occurs. The resultant loss of signal de-energizes the relay indicating that a high level exists.
