Problems solved by technology

[0004] Since the domestic differential pressure transmitter verification device is still in its infancy, and there is no corresponding period verification method, the main measurement standard of the differential pressure transmitter can only be tested by means of detection, and the overall measurement device cannot be fully verified.

Abstract

The invention provides a period checking method for a differential pressure transmitter verification device. The method comprises: firstly, a period checking data is calculated according to main standard submitting time; secondly, a checking standard is verified by using a verification device on the period checking data; thirdly, the checking standard is installed on the verification device, the verification device is started by invoking a testing program automatically to test the checking standard, and testing data are uploaded to a background control system uniformly; and fourthly, the background control system carries out an automatic analysis on a performance index of the verification device based on the testing data. The method has the following beneficial effects: the verification device can be tested automatically and regularly to guarantee accuracy and stability of the metering performance of the device; and precise operation of the differential pressure transmitter verification device can be guaranteed effectively and the application prospect of the method is wide.

Description

technical field [0001] The invention relates to a period check method of a test device for a differential pressure transmitter. Background technique [0002] In the current verification regulations, there is no relevant requirement for the overall inspection of the differential pressure transmitter verification device. It is only necessary to transfer the value of the standard meter to carry out the work. The method, the frequency of use, the aging of the equipment and the tightness of the connecting parts may change the overall measurement performance of the verification device, so that the uncertainty of the output pressure of the verification device will be increased. In order to ensure the daily stable and efficient operation of the differential pressure transmitter verification device and the accurate and reliable value of the standard equipment in the verification device between two inspections, it is necessary to conduct an interim inspection of the differential press...
