Description
Technical field
This utility model patent relates to a kind of detection sensor device, particularly relate to a kind of sensor device for detecting fluid leakage being easily installed, possible leakage it is directly attached to: on wall, pipeline, holding vessel, equipment or certain parts in the way of band, therefore, it is easily installed, the strip-type sensor device cutting according to required length and using simultaneously.
Background technology
The most widely used liquid leakage sensor, senses including to the detection of water, oil and other chemical liquid mediums, and most typical have three classes: one, cable-type leak sensor, and two, banding pattern leak sensor, modular type leak sensor；
First cable-type sensor, it it is a kind of relatively reliable liquid leakage detecting sensor, the position detecting leakage fast and accurately can be compared, in the case of fluid leakage, cable sensor is capable of detecting when a certain change (electric potential difference) of voltage on the resistance of leak fluid that flows through with electric current, is thus advantageous to accurately detecting and goes out liquid leakage and its position；
The shortcoming of cable-type sensor is:
(1) cable-type leak sensor is sufficiently expensive；
(2) and length sets in time dispatching from the factory, it is impossible to arbitrarily changing, thus limit the selection of use, fixing length can cause use inaccuracy or a certain degree of waste；
(3) cable-type sensor is installed needs extra mounting bracket, owing to a lot of equipment itself do not design vacant installing space, causes certain trouble even can not install installing, too increases installation cost simultaneously；
(4) after liquid leakage being detected, need the long period to make a return journey moisture removal, be connected with external equipment and there is certain difficulty.
Secondly, banding pattern sensor, also referred to as banding pattern wire sensor, is to detect leakage according to change resistance value, moisture and conductive cable contacts when electric current flows along this cable, resistance value can change, the exercisable resistance value of banding pattern liquid leakage sensor is 0 Ω-50M Ω, and its output is 30V DCV to the maximum, its length of cable up to 50M, and the greatest length of banding pattern sensor is 10M, it is that a kind of cost is relatively low and detection leak area is relatively wide, installation is relatively easy installation；
The shortcoming of banding pattern sensor is:
(1) in rugged environment, such as high humidity or current intelligence, arise that the biggest error, be difficult to detect accurate leak position；
(2) installation is affected the most significantly, owing to complicated mounting means itself produces a lot of trouble can to installation manufacture.Owing to network and PC system initial capitalization spend very big, the length of cable of sensor is set to change, and is very restricted (such as: 1M, 2M, 5M, 10M, 20M) therefore this product cost low in using；
(3) with during external connection only with the method for relay contacts, which limit the use of connection equipment.
Again, modular type leak sensor, by being arranged on the optical sensor (optical receiver in north material shell, optical transmitting set), it is not detect in the state of fluid and receives the electron beam coming from electron emission unit, come from the electron beam probing of electron beam emission unit to fluid, electron beam will not be received with the change optical receiver of refractive index, the voltage of its input is 12VDC-24VDC, response time is 50ms, the temperature used is 10 DEG C-60 DEG C, shell generally uses and is made up of polypropylene, it is under a kind of relatively low cost, to detect the part that may reveal, and automatic alarm and alarm lamp can be exported and unrelated with adjacent equipment.
The shortcoming of modular type leak sensor is:
(1) can only detect whether specific part is revealed, be impossible to detect when the position revealed changes；
(2) rigid connection with external equipment it is unfavorable for；
(3) need extra sensor fixing means, install simultaneously and need to spend the longer time；
Therefore, for the number of drawbacks of above-mentioned traditional detection liquid leakage sensor, need existing technology is reasonably improved.
