Problems solved by technology
Capillary pressure transmitters cannot be calibrated to bury hidden dangers for the safe and stable operation of the process system. At the same time, because capillary pressure transmitters are mainly used in high-risk places such as high radioactivity, strong acid, and strong Radiation exposure or corrosion damage, maintenance personnel should not work in this place for a long time

Description
technical field [0001] The invention belongs to the field of instrument measurement, and in particular relates to a quick calibration device and method for a capillary pressure transmitter. Background technique [0002] The pressure transmitter is the most commonly used sensor in the industry. It is a device that converts pressure into a pneumatic signal or an electrical signal for control and remote transmission. It can measure physical pressure parameters such as gas and liquid felt by the measuring element sensor Convert it into a standard electrical signal (such as 4-20mADC, etc.) to supply secondary instruments such as indicating alarms, recorders, regulators, etc. for measurement, indication or process adjustment. It is widely used in various industrial control environments. It can not only measure the pressure of various media in pipelines, containers, etc., but also measure the differential pressure before and after the pipeline of the pump body, the flow of medium i...
