Water level detection sensor

Abstract

The invention provides a water level detection sensor. The water level detection sensor comprises a sensor body, a rubber ring and a cable; two clamping hooks are fixedly connected to the middle positions of the top end surface and the bottom end surface of the sensor body, and a detection plate is mounted on the front end surface of the sensor body; the cable penetrates through a fastening base to be connected with an electrical connector on the rear end surface of a plug through soldering tin; and a fastening nut structure is composed of the nut body, a threaded groove, a cylindrical groove,a conical groove and the rubber ring. The detection accuracy of the device is high, especially the detection in a motion state; first, through the setting of a rectangular groove on a rectangular block, when the detection is carried out in the motion state, on the one hand, the constraint of the rectangular groove can reduce the splash of moisture in contact with a detection copper wire, therebyimproving the detection accuracy; and on the other hand, a detection error caused by the sputtering of the moisture in a water tank on the detection copper wire can be avoided.

Description

technical field [0001] The invention belongs to the technical field of water level detection equipment, and more specifically relates to a water level detection sensor. Background technique [0002] The water level sensor in the container transmits the sensed water level signal to the controller, and the computer in the controller compares the measured water level signal with the set signal to obtain a deviation, and then sends a signal to the water supply electric valve according to the nature of the deviation. "Open" and "Close" instructions to ensure that the container reaches the set water level. After the water inlet program is completed, the computer in the temperature control part sends an "open" command to the electric valve that supplies the heat medium, so the system starts to heat the water in the container. to the set temperature. The controller issues the command to close the valve, cut off the heat source, and the system enters the heat preservation state. I...

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a water level detection sensor to solve the existing problem that the water level sensor installed in the water tank of the vehicle is prone to turbulence due to the long-term turbulence due to low stability. The connecting plug or the wire head welded with solder is loose or disconnected, which leads to the decrease of the stability of the sensor; moreover, the detection accuracy is low, and the unevenness of the vehicle is likely to occur when the vehicle is driving due to the unevenness of the road surface. Regular shaking, and the water tank will also shake irregularly with the vehicle, the sensor installed in the existing water tank cannot provide high water level data when the vehicle is in motion, and it is easy to cause the driver to misjudge the problem
