Application

The general purpose guard capacitance point liquid level switch provides 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. For best performance, install the sensor vertically and the RF guard circuit eliminates the coating signal path between the active and reference electrodes. The submersible polypropylene liquid level sensor can be mounted inside the tank or through non-metallic tank walls as a high level alarm or low level alarm.
