The Conductivity Level Switch 501 is a simple and price competitive system for on/off level measurement. Its typically used in applications to control pumps and valves, to alert high or low levels or to detect water on the floor.

The system includes a signal amplifier (501) that can operate up to tree level electrodes. The stainless steel electrodes can be cut to the desired length and connected via the electrode base to the amplifier.
The amplifier can be configured to either pump in or out of the tank. The electrode base can be mounted on a standard MJK bracket directly on the wall or in combination with MJK modular fittings. The 501 transmitter is for DIN-rail mounting.
