Description

TECHNICAL FIELD

[0001] The application relates to the technical field of sensors, in particular to a cylinder column type tension and compression sensor. BACKGROUND

[0002] The tension and compression sensor, also known as a resistance strain sensor, belongs to the weighing sensor series and is a device for converting a physical signal (tension or pressure) into a measurable electrical signal output.

[0003] The existing tension and compression sensor is installed on a test device or structure, and then the cable of the sensor is correctly connected to a data acquisition system. After installation, zero point calibration is performed to ensure that the output of the sensor is zero when there is no external force. Then, according to the experimental or production requirements, appropriate tension or pressure is loaded to the sensor, and the output signal of the sensor is observed to ensure that it can correctly reflect the change of the force.

[0004] However, the conventional tension and compression sensor is usually in the form of an S-shaped shear beam structure. In actual work, it cannot be adapted to the case of having an air duct. For example, in gas flow measurement, the sensor may need to pass through a hollow air duct to measure the flow rate, flow rate and other parameters of the gas. However, due to the compact structure of the conventional tension and compression sensor, it may not be directly installed in the hollow air duct, so it cannot accurately measure the gas flow. The structure of the cylinder column type with an air duct in the middle is not common on the market, and most of the ones with an air duct in the middle are assembled parts, which have poor coaxiality and cannot meet the actual use requirements.

[0005] Therefore, it is necessary to provide a cylinder column type tension and compression sensor to solve the above problems.

[0006] It should be noted that the above information disclosed in the background section of the present application is only used to understand the background technology of the concept of the present application, and therefore, it can contain information that does not constitute prior art. SUMMARY

[0007] Based on the above problems existing in the prior art, the present application solves the problem of providing a cylinder column type tension and compression sensor that can be used in different scenarios.

[0008] The technical solution adopted by the application to solve the technical problems is a cylinder column type tension and compression sensor, comprising a seat body; a hollow assembly is arranged on the seat body, and the hollow assembly comprises a rod body arranged on the seat body and a cylinder arranged at one end of the rod body away from the seat body; wherein the interiors of the seat body, the rod body and the cylinder are coaxially provided with a hollow air duct.

[0009] Further, the first and second threads are arranged at the two ends of the hollow air duct.

[0010] Further, the first screw thread is arranged inside the barrel body, and the second screw thread is arranged inside the seat body.

[0011] The beneficial effects of the present application are: the cylinder column type tension and compression sensor provided by the present application is provided with a hollow component, so that in the test scene with an air duct, the hollow component can be connected with the air duct, so that the hollow air duct is in communication with the air duct, and then in the use process of the air duct, negative pressure or positive pressure is applied to the hollow air duct through the air duct, so that the sensor is stressed under the driving of the negative pressure or the positive pressure, thereby detecting the use environment in the air duct, and achieving the effect of being applicable to different scenes.
