Level Switch
Conductivity Level Switch is a simple, low cost, point level measurement switch designed for level detection of conductive liquids having low densities, high viscosities, containing solid particles and to detect interface between non-conductive and conductive liquids. The probes work through the variation of the electrical resistance between the reference electrode and the level-control electrode. Conductivity level switches detect the level resistance when their electrodes are covered by the medium. If the tank is made of plastic, concrete, or any other nonconductive material, an additional electrode is required as a reference
Conductivity Level Switches are available with stainless steel 316 electrodes as standard
Suitable for many chemicals and aggressive media which are conductive in nature and dirty liquids, liquids with high solid content
Construction available with both Solid probes & Suspended probes to suit fitting requirement
It is a simple, low cost, point level controller designed for detecton of conductive liquids, having low densites, high viscosities, containing solid particles and interface between nonconductive and conductive liquids.
CONSTRUCTION & OPERATION It comprises of a probe, wired to a level controller. The probe holds one common reference/common electrode and one or multiple “Control Electrodes” depending upon the number of levels to be controlled. All the electrodes are suitably insulated to avoid electrical bridging. The lengths of “Control Electrodes” correspond to the height of preset level points to be controlled and the length of the “reference/common Electrode” is kept slightly longer than the longest “Control Electrode”. If tank is conductive, it can be used as a reference/common electrode. Then number of control electrodes equals number of preset levels. Level controller houses sensing electronics consisting of power supply and signal conditoning circuit which provide a “Low AC Voltage” across mass and control electrodes. On liquid reaching preset level point electrical circuit gets completed - generating a signal which is amplified to actuate a relay, those potential free contacts are available for subsequent operations. On “Level Falling” the circuit breaks, deactivating the relay
