Switch-Tek SuperGuard Capacitance Switch

The general purpose guard capacitance level switch is a great choice for a wide range of aqueous based conductive liquids with light coating, crystallizing or scaling characteristics. Media examples include copper sulfate and brine. The 1A relay provides a reliable switch interface with remote devices such as a PLC, SCADA or alarm. The submersible sensor is universally mounted through the wall or inside the tank.

Features
  • Guard circuit optimizes sensor performance in coating type media
  • Rugged PP sensor and cable rated NEMA 6 or IP68
  • 1A relay selectable NO or NC via power supply wiring polarity
  • Compatible with Flowline alarm, controller and fitting accessories


Tech Tip
The capacitance switch has a RF guard circuit that eliminates the coating signal path between the active and reference electrodes. For best coating performance, install the sensor horizontally through the side wall of a non-metallic tank. Its coating level made simple.
