Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of air pressure detection, and particularly relates to a quality detection device for a differential pressure sensor. Background Technique
[0002] A differential pressure sensor detection device is a device used to detect the performance and accuracy of a differential pressure sensor. This detection device usually simulates different pressure environments to test performance indicators such as the measurement accuracy, response time, and stability of the differential pressure sensor. It can generate accurate pressure values and compare them with the measurement results of the differential pressure sensor to determine whether the differential pressure sensor is working properly. The differential pressure sensor detection device can accurately measure the actual values under different pressures and compare them with the readings of the differential pressure sensor to judge whether the measurement accuracy of the sensor meets the requirements. It can quickly change the pressure environment and observe the response speed of the differential pressure sensor to ensure that it can promptly reflect the pressure change. Moreover, the differential pressure sensor detection device can maintain a certain pressure environment for a long time and monitor whether the output of the differential pressure sensor is stable to evaluate its long-term working reliability. When the differential pressure sensor malfunctions, the detection device can help determine the cause of the failure, such as sensor damage, connection line problems, etc.
[0003] For existing differential pressure sensor detection devices that require air pipes to be led in two spaces respectively, when there is no reserved air pipe or the reserved position is inappropriate during the construction process, it will increase the construction difficulty and cost. Some existing detection devices may have specific requirements for installation conditions, such as specific installation positions, angles, etc., which may limit their application in some complex or space-constrained environments.
[0004] Secondly, existing differential pressure sensor detection devices are affected by changes in environmental temperature, humidity, etc. For example, temperature changes may cause an increase in the measurement error of the sensor, or when the detection device is affected by external vibrations or human activities, it may also interfere with its normal operation and affect the accuracy of the measurement results.
