With the advancement of instrument technology, differential pressure transmitters of various brands are developing in the direction of high precision and intelligence.

Differential pressure transmitter is the most commonly used weight transmitter in industrial practice. It is widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other industries.

Differential pressure transmitters are widely used in factories. In order to ensure their normal operation and accuracy, regular inspection and calibration are necessary. A method for on-site calibration without removing the pressure guiding tube is now introduced.
