Description

Technical Field

[0001] This utility model relates to the technical field of barometric pressure sensor testing equipment, specifically a barometric pressure sensor testing equipment. Background Technology

[0002] As an important environmental sensing element, barometric pressure sensors are widely used in automotive tire pressure monitoring systems, smartphone altitude measurement, drone altitude control, and industrial pneumatic equipment pressure detection. Their performance parameters directly affect the reliability of end products, so they must be fully tested by professional testing equipment before leaving the factory.

[0003] A search revealed a patent, CN221549907U, which discloses a barometric pressure sensor testing device. This device includes a workbench and a base. The top of the workbench is fixedly connected to the bottom of the base, and a display screen is fixedly connected to the top of the base. A shelf is fixedly connected to the bottom of the workbench, and an air tank is clipped onto the inner wall of the shelf. An air outlet pipe is fixedly connected to the side of the air tank. A stabilizing testing device is installed on the top of the workbench, and a barometer is fixedly connected to the inner wall of the stabilizing testing device. This device utilizes the gravity exerted when the cover is lowered, combined with the interaction of the internal components of the stabilizing testing device, such as the compression rod, air bladder, and stabilizing plate, to achieve a vertical stabilizing effect on the untested barometric pressure sensor. This stabilizes the sensor, reducing errors caused by sensor instability and improving testing efficiency and accuracy.
