1安全阀离线校验概况目前,国内大量使用的安全阀离线校验台采用目视从精密压力表上读取测试数据的测试方法,测试精度很大程度上取决于操作人员的熟练程度、责任心和工作经验,难以获得精度稳定可靠的测试数据。同时,由于测试数据无法进行自动记录,校验原始记录、校验报告中的测试数据是由校验员在完成校验后人工填写或录入,工作效率低下,数据的真实性、可靠性无法得到保证。随后有人提出了用PC控制、对安
At present, a large number of domestic use of safety valve off-line calibration platform using visual test data from precision pressure gauge test method, the test accuracy depends largely on the operator's proficiency, responsibility Heart and work experience, it is difficult to obtain stable and reliable test data. At the same time, the test data can not be automatically recorded, the original record is verified, and the test data in the verification report is manually filled in or entered by the verifier after completing the verification. The work efficiency is low, the authenticity and reliability of the data can not be obtained Guarantee. Then came the PC control, security
