Product description
Description
The relay monitors the level of conductive liquids. The operating principle is based on the measurement of the apparent resistance of the liquid between two immersion probe. If the measured value is lower than the threshold value, the relay changes its switching status displayed on the front side. In order to exclude electrolytic phenomena, the probes with alternating current. Via a front rotary switch can select the desired function and the desired sensitivity range can be set.
