The invention discloses a production method of a water sensor probe structure. The water sensor probe structure includes an outer shell of a sealed structure welded by two half shells, and a row is longitudinally opened along the side of each half shell for Install the small hole of the detection sheet, install the detection sheet or insulating sheet in the small hole, use the insulating sealing material to insulate and seal between the detection sheet and the inner wall of the small hole, and then put the two detection conductors into one of the two detection conductors respectively. In the half-shell, and then the non-insulated surface of the detection conductor is installed in contact with the inner surface of the detection piece and bonded, after the detection conductor is installed inside each half-shell, the two half-shells are butted An insulating partition is installed in the middle of the two detection conductors, and then the two half-shells are welded together along the edges. The production method of the probe structure of the water sensor provided by the invention produces a water sensor structure with a multi-contact structure, which ensures the sealing performance, insulation performance and pressure bearing capacity of the sensor.
Description
technical field [0001] The invention relates to a production method of a water sensor probe structure, belongs to the field of sensor elements, and is specifically applied to detecting water levels of automobile water tanks and machine tool coolants. Background technique [0002] The probe structure of the liquid level sensor in the prior art is just a solid metal probe structure. Usually, a probe can only detect one liquid level data. If multiple liquid level data needs to be detected, multiple sensors must be used for detection. However, for a product with a certain structure such as an automobile water tank, it is obviously unrealistic to add additional openings to install sensors. The advanced sensor probe will provide a good choice for the transformation and improvement of the car. [0003] The existing probe structure generally can only detect a specific water level fixedly, and the standard for detecting the water level cannot be adjusted as required. [0004] In th...
