Level Switches : LP15
Switch-Tek™ Guard Capacitance Level Switch
Application
The general purpose guard capacitance point level switch provides reliable high or low liquid level detection of water based conductive liquids with light coating, crystallizing or scaling characteristics with a 1A relay output. Media examples include copper sulfate and brine. The RF guard circuit eliminates the coating signal path between the active and reference electrodes. The submersible polypropylene liquid level sensor is universally mounted through non-metallic tank walls or inside the tank as a high level alarm or low level alarm.
Features
Guard circuit optimizes performance in coating type media
Submersible PP sensor body and cable for corrosive liquids
60VA relay selectable NO or NC via power supply wiring polarity
Compatible with Smart Trak and Switch-Pak installation fittings
