Switch Tek Capacitance Level Switch Overview The general purpose guard capacitance level switch is offered in PP with 1A relay provides a reliable switch interface with remote devices such as a PLC, SCADA or alarm. The capacitance switch has a unique RF guard circuit which eliminates the coating signal path between the active and reference electrodes. The level switch is broadly suited for water based conductive liquids with light coating or scaling characteristics. The submersible sensor is universally mounted through the wall or inside the tank.
Switch Tek Capacitance Level Switch Features • Guard circuit optimises 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
Typical Switch Tek Capacitance Level Switch Applications
• Aqueous based conductive liquids such as copper sulphate and brine
