差压变送器在应用中的故障诊断与比较

Fault Diagnosis in Application and Comparison of Differential Pressure Transmitters

差压变送器广泛应用于石化行业中液位、流量的测量。对差压变送器在实际应用中遇到的问题进行了探讨,对双法兰差压变送器与普通差压变送器进行了比较。比较结果表明,只有正确使用和维护差压变送器,才能使它在行业生产中发挥更好的作用。压力变送器、差压变送器和双法兰差压变送器在维护检修方面具有互通性。

Differential pressure transmitters are widely used in level and flow measurement for petrochemical industries, the problems encountered in practical applications are investigated. The double flange differential pressure transmitter is compared with conventional differential pressure transmitter, it is found that only the differential pressure transmitter being properly used and maintained, it may play a better role in industrial production. In maintenance and overhaul of pressure transmitter, differential pressure transmitter and double flange differential pressure transmitter, interoperability is provided with.
