Switch-Tek SuperGuard RF Capacitance Level Switch From Flowline
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.
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
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
