Working Principle
The SHE Series Electrode Type Liquid Level Switch is suitable for conductive liquids and works together with a controller. When the conductive liquid does not contact the electrode rod, there is no current between the electrode rods. When the conductive liquid reaches the electrode rod, the weak current supplied to the rod passes through the liquid to the controller, and the controller then actuates the control signal. This working method allows the product to be used for long-term liquid level control and alarm applications.
Technical Characteristics
The controller has a compact appearance and is suitable for installation inside a control cabinet.
The electrode rod uses industrial-grade material with durable structure.
The rod length can be freely combined according to application needs.
It can be used for local liquid level control or alarm.
The modular design is convenient for different point-level control tasks.
