Description

Technical Field

[0001] This utility model relates to the field of differential pressure sensor detection technology, and in particular to a quick-connect device for testing the performance of differential pressure sensors. Background Technology

[0002] A differential pressure sensor is a sensor used to measure the difference between two pressures. It is typically used to measure the pressure difference across a device or component. The change in pressure difference is converted into a change in the pressure-sensitive element built into the sensor. The output is then processed and modulated from the weak signal generated by the deformation of the pressure-sensitive element, or further processed by analog-to-digital conversion and chip computing to output an analog or digital signal. In fluid control fields such as aerospace and special machinery, differential pressure is required to measure physical quantities such as oil supply systems, lubrication systems, hydraulic systems, and pneumatic systems. It is used to detect the pressure difference across the system pipeline. Differential pressure sensors are commonly used tools in the industrial field to measure the pressure difference of gases or liquids. In the manufacturing process of differential pressure sensors, pressure testing is required to test their performance. Therefore, we designed a quick-connect device for testing the performance of differential pressure sensors. Utility Model Content
