The Dynatrol® Type CL-10RH liquid level probe and 102B control switch are used for application to either high 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.
Versatile
This level control is
applicable to the level detection of a wide range of liquids and slurries. The
detector may be mounted in any position on a vessel or in piping.
Rugged
No packing gland,
diaphragm, float, bearing, bellows or other troublesome pressure
seal is used in the Dynatrol level switch 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 liquid level applications.
All components have been 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 the paddle vibration amplitude. When the paddle
comes into contact with the
process media its amplitude of vibration decreases and the
output voltage drops to a very low value. This
change in output signal operates the SPDT
contacts of the EC-102B Relay Switch Receiver.
