Switch-Tek™ LP15 Guard Capacitance Level Switch

DOWNLOADS

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 Switch-Pak fitting for vertical tank installation
