Introduction

Conductive level switches are designed to control the level of all conductive mediums with up to 5 different points of level control. Models are available with fixed rigid rods, removable rigid rods, with pendular electrodes attached to the housing with cables, and also built-in units. Wetted parts and connections are made with 316 S.S. and are isolated with a Teflon joggle. Rods can be Teflon coated, when the probe is applied in agressive or sticky mediums prone to build up. The probes work through the variation of the electrical resistance between the reference electrode and the level control electrode. Conductive Level Switches detect the level resistance when their electrodes are covered by the medium. An electrically conductive tank wall may be used as the reference electrode. If the tank is made of plastic, concrete or any other nonconductive material, an additional electrode is required to act as a reference.

Handling

Do not turn or handle by the housing

Use the correct tool to screw the switch Seal the thread with teflon tape before screwing

Installation

Pre-Installation Checks: Before installing the Conductive Level Switch, check if the wire connections are correct and that the available power supply is compatible with the controller. Check if the operating pressure and temperature of the process corresponds to the correct model of the sensor.

Installation The Conductive Switch must be installed utilizing the type of connection provided. The tank must be free from turbulence or vortices throughout use. When tightening the switch, only use the hexagon fitting to achieve a seal, do not twist by the housing. When installing the switch either directly to the tank, or utilizing a “T� connection, make sure that the rod extends beyond the inner wall of the tank so that internal build up or other debris does not interfere with the performance of the switch. Scratching the coating could interfere with the probe performance.

When cleaning the rods use a soft brush or any other similar object.
