Description

Technical Field

[0001] This utility model relates to the field of integrated sensor technology, specifically an integrated sensor with anti-interference function. Background Technology

[0002] A sensor is a detection device that can sense the information being measured and transform the sensed information into an electrical signal or other required form of information output according to a certain rule, so as to meet the requirements of information transmission, processing, storage, display, recording and control.

[0003] For example, the announcement number CN216524090U (named "An Integrated Liquid Level and Temperature Sensor") includes a tube body with an insertion end for inserting a conductive liquid and a measuring end for displaying the liquid level. The tube body includes an outer tube and an inner tube, which serve as the two poles of a capacitor. The outer tube is fitted over the inner tube, and there is a gap between the inner and outer tubes. Both the outer and inner tubes are made of conductive metal. The inner or outer tube is covered with insulating material, so that one tube is insulated from the liquid and the other tube is conductive. There is an initial capacitance between the outer and inner tubes. Changes in the height of the liquid cause changes in the capacitance between the outer and inner tubes. The measuring end of the tube body is connected to a transmitter. The transmitter can measure the capacitance change between the outer and inner tubes and convert the capacitance value into a liquid level display. With one sensor, both the temperature and the liquid level can be measured, reducing the number of devices and installation space, and lowering the cost.

[0004] The aforementioned integrated sensor achieves synchronous detection of liquid level and temperature through a set temperature detection mechanism and a liquid level detection mechanism. However, the sensor has poor anti-interference performance during use, resulting in poor stability during signal transmission. Therefore, we provide an integrated sensor with anti-interference function. Utility Model Content

[0005] The purpose of this invention is to provide an integrated sensor with anti-interference function to solve the problem mentioned in the background art that the existing integrated sensor achieves synchronous detection of liquid level and temperature through the set temperature detection mechanism and liquid level detection mechanism, but the sensor has poor anti-interference performance during use, resulting in poor stability during signal transmission.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated sensor with anti-interference function, including a mounting base, a radar liquid level sensor is provided at the upper end of the mounting base, a support plate is provided on one side of the radar liquid level sensor, a temperature sensor is provided at the upper end of the support plate, and an antenna mechanism is provided at the lower end of the mounting base, wherein the antenna mechanism and the temperature sensor are an integrated structure.

[0007] Also includes:

[0008] A shielding cover is installed on the outside of the radar level sensor, and two extended cover plates are integrally formed on one side of the outer wall of the shielding cover, with the two extended cover plates located on both sides of the temperature sensor respectively.

[0009] The top cover frame is located at the upper end of the shielding cover and the two extended cover plates, and assembly bolts are provided at the connection positions between the top cover frame and the two extended cover plates. The top cover frame is fixedly connected to the two extended cover plates by the assembly bolts.

[0010] A cable bundle is positioned on one side of the temperature sensor, and two sensor wires are threaded through the inside of the cable bundle. The two sensor wires are electrically connected to the radar level sensor and the temperature sensor, respectively.

[0011] Preferably, the mounting base has an integrally formed lowering conduit inside, and a temperature detection probe is provided below the lowering conduit. The size of the temperature detection probe is smaller than the diameter of the lowering conduit.

[0012] Preferably, a probe wiring device is provided between the temperature detection probe and the temperature sensor, and the probe wiring device is connected to the lowering conduit.

[0013] Preferably, mounting screw holes are provided at the connection positions of the two extension cover plates and the assembly bolts, and the mounting screw holes and the extension cover plates are an integral structure.

[0014] Preferably, mounting rods are welded to the inner walls of both sides of the support plate, and one end of each mounting rod is glued to the outer wall of the cable bundle tube.

[0015] Preferably, two support rods are provided at the connection position between the support plate and the mounting base, and the two ends of the two support rods are welded to the support plate and the mounting base respectively.

[0016] Preferably, both ends of the cable bundle are glued and fixed with end caps, and the wiring of the two sensors is connected to the two end caps.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] The mounting base, shielding cover, extension cover plate, top cover frame, cable tie tube, and end cap of this utility model are all made of aluminum, providing shielding protection for the radar level sensor and temperature sensor to achieve anti-interference. While providing shielding protection, the outer cover also protects the radar level sensor and temperature sensor to prevent damage. This overcomes the problem that existing integrated sensors achieve synchronous detection of liquid level and temperature through set temperature detection mechanisms and liquid level detection mechanisms, but the sensor has poor anti-interference performance during use, resulting in poor stability during signal transmission.
