Dynatrol® CL-10GH Liquid Level Switch

The Dynatrol® CL-10GH Liquid Level Detector and EC-501A(G) Control Unit is used for high, intermediate or low point level detection of liquids and slurries. A unique vibrating principle permits design and operation features not available with other types of liquid level detectors.

Dynatrol® CL-10GH Liquid Level Switch


Dynatrol® Liquid Level Detectors can be used on a wide range of liquids and slurries and can be mounted in any position on a vessel or in piping.  No packing gland, diaphragm, float, bearing, bellows or other troublesome pressure seal is used in the Dynatrol® Detector design. This unique design provides rugged construction yet a sensitive transmission of vibration energy through a rigid, all-welded pressure seal.  Corrosion resistant coatings are available if required for specific applications.  All components are constructed for long operating-life and require no field adjustments.

Principle of Operation

The Dynatrol® liquid level paddle is driven into vibration by a driver coil. A second coil produces a voltage proportional to a 0-3/4-inch range of level. As the process covers the paddle, the output responds proportionally by transmitting a 1-5mA or 4-20mA signal.
