[0022] A multifunctional liquid level automatic monitoring instrument sensor detection device comprises a connecting device 1 and a valve 2. Five connecting devices 1 are provided, and five valves 2 are provided. The five connecting devices 1 and the five valves 2 are staggered. The five connecting devices 1 are threadedly connected to the five adjacent valves 2. The left end of the connecting device 1 on the left is threadedly connected to an air pump connecting end 3.

[0023] In this embodiment, the connecting device 1 includes a metal part 11, which is a cross-shaped structure. The left and right ends of the metal part 11 are both provided with a No. 1 internal thread 13. The front and rear ends of the metal part 11 are fixedly connected with connecting heads 12. The outer surfaces of the two connecting heads 12 are both hexagonal structures, and the two connecting heads 12 are both provided with No. 2 internal threads 14; the valve 2 includes a valve body 21 and a rotor 23. The left and right ends of the valve body 21 are both fixedly connected with an external convex connecting end 22, the outer surface of the rotor 23 is a corrugated structure, and the upper end of the rotor 23 is fixedly connected with two pointers 24; the metal part 11 is threadedly connected to the external convex connecting end 22 through the No. 1 internal thread 13; the metal part 11 is an internal hollow structure; the external convex connecting end 22 extends into the metal part 11.

[0024] Through the above scheme: after connecting the air pump connection terminal 3 to the external air pump, 12 on the five 1s are connected to the sensor to be detected as needed. After the air pump injects the gas into the sensor through 1, the pressure value of the sensor is detected. By setting 2, it is convenient to monitor in batches.

[0025] It should be noted that the utility model is a multifunctional liquid level automatic monitoring instrument sensor detection device. During use, the air pump connection end 3 is first connected to the connection device 1 located on the far left, and then the air pump is directly connected to the air pump connection end 3. There are five connection devices 1, each of which is equipped with two connectors 12. After connecting to the sensor through the connector 12, the use of these connectors 12 in conjunction with the valve 2 can achieve rapid inspection and screening detection of different sections. It is also convenient to perform pressure control in sections, apply different pressures according to the sensor model to be detected, and compare the waveform performance of the microphone under the same conditions. This efficient inspection and screening process benefits from the sub-control function of the valve 2, which facilitates the simultaneous acquisition of the initial value of the pressure sensor and the specific pressure parameters of each sensor under the same pressure conditions. Through this process, the calibration parameter printing of each sensor can be easily completed, which greatly improves the efficiency of the production process and eliminates the tedious steps of pressure calibration of each sensor one by one.
