SLW:Conductive Liquid Level Sensor/Switch

Item Code: SLW

Conductivity Level Limit Switch (Sense the level of Water or other Conductive Liquids that have free ions)
Principle
A low AC voltage is applied between the probe electrode and the tank wall (or reference electrode in case of insulated tanks). When the liquid comes in contact with the electrode tip, a conductive path is established between the sense electrode and the tank wall / reference electrode. This current is sensed, amplified and made to operate a relay whose contacts in turn can be used for annunciation / control.

Highlights
  • Allows long connectivity between probe and evaluation unit
  • No special cable required for signal transmission
  • Low voltage on probe for operational safety
  • No moving parts, longer running life
  • Variety of probes for unique process conditions
Applications
  • Switch pumps off when tank is full, to avoid overflow
  • Maintain a constant level to avoid material wastage
  • Switch off pumps when running dry
  • Identify empty tank to avoid wear-tear,production stoppage
