Water Guard

Automatic monitoring of water supply of laboratory equipment and household appliances.

Application

Solenoid valve system for automatic monitoring the leaks of water supply pipes and tubes. To be used in household and laboratory equipment.

Function

Upon energizing, the control electronics opens the solenoid valve. The sensor can monitor a water film of approximately 0.5 mm and sends a signal to the electronics. The solenoid valve is closed and an audible alarm sounds. This condition is then reset by breaking the supply voltage.

Installation

Fully automatic monitoring can be built in to the supply pipes of a water source. The sensor lays on the floor and is connected with the control electronics through a cable. The solenoid coil and control electronics are built in to a plastic housing. The voltage supply occurs over a network cable with an adapter connector.

Characteristics

Reduces the usage of electricity by sinking the electronic holding current
A fixed setting within the inner parts of the valve are hindered through an autmatic, daily valve closing impulse
