Leakage detection sensor

Abstract

The invention discloses a leakage detection sensor. The leakage detection sensor comprises a leakage detection sensor transmitter, a communication outer tube and a leakage detection sensor probe, wherein the communication outer tube is arranged between the leakage detection sensor probe and the leakage detection sensor transmitter; one end of the communication outer tube is fixedly connected withthe leakage detection sensor transmitter through a nut; the other end of the communication outer tube is fixedly connected with the leakage detection sensor probe through a nut; a light source component, a receiving component, a signal processing unit and a communication unit are arranged inside the leakage detection sensor probe; a probe communication unit, an arithmetic unit, an indicating unitand an RS485 communication unit are arranged inside the leakage detection sensor transmitter. The leakage detection sensor has the advantages that detection accuracy is high, and the leakage detectionsensor is not easily interference by outside, and the leakage detection sensor can be widely promoted and applied.

Description

technical field [0001] The invention belongs to the technical field of leakage detection equipment, and in particular relates to a leakage detection sensor. Background technique [0002] The leak detection sensor consists of two parts: a leak detection sensor probe and a leak detection sensor transmitter. The leak detection sensor is a practical infrared liquid recognition sensor leak detection that involves the detection of liquids such as oil or water in double-layer oil tanks or double-layer pipelines in gas stations. In the prior art, analog circuits are mostly used to detect liquids. The detection accuracy is not high, and it is easy to be interfered by the outside world, resulting in false detection results. Contents of the invention [0003] The object of the present invention is to provide a leak detection sensor to solve the problems raised in the background art above. [0004] In order to achieve the above object, the present invention provides the following te...
