EN SERIES

LIQUID LEVEL CONTROL

UL listed CSA recognized
• Pump Up or Down Control
• DIN-Rail Enclosure
• 5 to 100
• SPDT 8 Amp Relay Output

CONTROLS

GENERAL FEATURES:

The EN series is designed to monitor conductive liquids such as tap water, waste water, sea water, coffee, etc. The principle is based on the measurement of the resistance of the liquid between two submerged probes. When this value is lower than the preset threshold selected on the dial of the unit, the output relay changes state. Applications are found in the environmental and chemical industries, food equipment machinery and food processing technology.

Regulation of two levels Minimum / Maximum

The output relay changes state when the level of liquid reaches the maximum electrode, with the minimum electrode submerged. It returns to its initial state when the minimum probe is no longer in contact with the liquid.

Regulation of one level:

Connect the maximum and common terminals together. The relay will change state when the minimum probe enters or leaves the liquid.

Note If the power break lasts for seconds or more, the relay reenergizes instantly if in mode and is deenergised if in mode.
