Model FE - Electrode Level Sensor

General Description

The FE series of level sensors are designed for point level indication of conductive liquids. Used in conjunction with one or more RE7000 relays, the FE can reliably detect up to 6 separate levels in tanks up to 6 meter deep. Model CE, cable suspended electrode level sensor, is available for deep wells with the cable length 6 meter standard and 20 meter maximum.

Operating levels can be easily changed in the field by cutting the length of the electrodes. The material of electrode is selected from 316SS, NW0001 0665, NW0276, and Titanium for the chemical compatibility.

Operational Description

A typical system consists of three major components, an electrode holder, the electrodes, and a relay unit.)

The electrode holder serves as a mechanical support for the electrodes and electrically insulates them from the tank. The electrodes are vertically mounted to the holder, above the liquid, with their lower ends positioned at the required actuation levels. The relay unit provides the voltage and current required (BV. 5mA AC Max.) for sensing as well as suitable relay outputs.

Applications

The FE series can be used in any suitable, conductive liquids. Applications involve both alarm point detection and pump valve control. Since the FE series contain no moving parts, it is very reliable and can be used in tanks where mixers or other moving equipment would damage ordinary float switches or level detectors.
