Description

[0001] WALL ADHESION TYPE LEAK DETECTION SENSOR [0002]

The present invention relates to a liquid leakage detection sensor for a wall-mounted type, and more particularly, to a liquid leakage detection sensor for a wall-mounted type that can detect harmful substances flowing on a wall surface.

A variety of leak sensors are used to detect leaks and leaks. Typically, a cable type leak sensor, a band type leak sensor, a modular leak sensor and the like are used.

The cable type leak sensor is a leakage and leakage leak sensor that detects the exposure of various liquids (water, oil, etc.) and informs the point where the liquid leaks accurately and quickly.

Leakage and leaking detection can detect leakages and leaks by detecting the electric current flowing along the conductor line, the potential difference caused by the resistance of leaked water or oil.

However, such a cable type leak sensor is expensive to install and has a limited use because the length of the sensor cable is fixed.

In addition, there is a problem in that it is difficult to install the sensor because additional brackets are required to install the sensor, additional cost is incurred, it takes a long time to remove physical properties after detection of leaking physical property, and connection with an external device is difficult.

Band type (BEND TYPE) Leak DETECTION SENSOR is able to detect the leakage according to the change of the resistance value when the water touches the wire while current is flowing through the wire.

However, there is a problem that the rate of occurrence of error is high due to high humidity or external impact, and the accurate leak position can not be easily confirmed.

In addition, there is a problem that the price is higher than the performance, and there is a problem that the bracket to be fixed to the floor at the time of installation is separately installed, so that it is difficult to install and there is no connection device other than a simple relay contact method when the external device is connected.

The modular leak sensor places a photosensor (light-receiving portion, light-emitting portion) in the plastic case and receives the beam of the light-emitting portion from the light-receiving portion without detecting the liquid, The beam (BEAM) can not reach the light receiving part due to the change of the refractive index.

This modular leak sensor is capable of detecting the danger of leakage at low cost, easy to install, self-alarming regardless of peripherals, and there is no error due to humidity. However, cable type (CABLE TYPE There is a problem that it is difficult to connect with a peripheral device.

In addition, the sensor according to the related art has a problem in that it is difficult to detect leakage of liquid flowing along the side wall of the container or the wall surface of the reservoir as sensors for detecting the fluid dropped on the floor.

Further, the sensor according to the related art has a problem that it can not be detected until the fluid to be detected flows down to the floor.
