A multi-point probe and a water leakage sensor

Abstract

The present invention discloses a multi-point probe used for a water leakage sensor. The multi-point probe comprises at least one detecting plate for connection with a resistance measuring instrument; a plurality of detecting holes is arranged in each of the detecting plates; each detection plate includes an upper conductive layer for electrical connection with the resistance measuring instrument, a lower conductive layer for electrical connection with the resistance measuring instrument and an interlayer insulation disposed between the upper conductive layer and the lower conductive layer; and each of the detection holes penetrates through the upper conductive layer, the interlayer insulating layer and the lower conductive layer. The invention also discloses the water leakage sensor. The multi-point probe and the water leakage sensor provided by the invention can enlarge the detection area by adding the large number of detection holes or detection points, so that a user is provided with convenience for arranging the probe and the sensor at a position where water leakage is likely to occur, and the capability of predicting leakage is greatly enhanced and the cost is effectively controlled.

Description

technical field [0001] The invention relates to the technical field of water leakage detection technology devices, in particular to a multi-point probe and a water leakage sensor. Background technique [0002] Such as figure 1 As shown, the water leakage sensors currently on the market generally have a limited number of even-numbered electrodes 1' (for example, a pair of electrodes, two pairs of electrodes, four pairs of electrodes, etc.), and use the resistance between the electrodes 1' when there is water and when there is no water. value changes to determine whether there is a water leak. [0003] However, its detection points are limited, and it can only detect water leakage at the position where the electrode 1' is located. At the same time, water leakage has random characteristics. The detection area of ​​the water leakage sensor in the prior art is small, which cannot meet the ability to predict the risk of water leakage. Contents of the invention [0004] The pur...
