Background
The pressure measuring system is mainly composed of a pressure transmitter, a data acquisition unit, a signal processing system, a terminal display unit and the like. The pressure variable is converted into a standard output signal which can be transmitted, whether the indexes of the pressure variable, such as measurement precision, performance and the like meet the requirements or not, whether the pressure parameter of the equipment can be accurately measured or not can be reflected into a control system in real time or not, so that the system can carry out safety protection on the production equipment, and operation and maintenance personnel can master the pressure condition in the equipment in real time, and the system is an important condition for safe operation of production. The pressure measurement system is mainly used for remote display and control of pressure, and the pressure measurement system usually works under the environments of high temperature, low pressure, corrosion, vibration and the like, and has a high failure probability, so that the pressure measurement system is very necessary to be calibrated regularly. The metering performance of a newly installed and used pressure transmitter over time, even the entire pressure measurement system, needs to be calibrated to ensure that the metering performance meets the process requirements of the production process.
There are two problems in the detection process at present: (1) it is common practice for pressure transmitter testing to remove components and send them to a laboratory for verification or calibration of the transmitter. However, this is equivalent to calibrating only the sensor of the measurement system, and not calibrating the subsequent parameter transformation module, which cannot obtain the accuracy of the whole pressure measurement system. (2) Because voltage signals are superposed on the remote transmission signal wire of the pressure transmitter, most field environments or conditions are not favorable for the disassembly of the measuring system, and improper disassembly can cause voltage signal short circuit to cause the damage of a signal conversion plate in the control cabinet.
Therefore, the pressure measurement system taking the pressure transmitter as the core is calibrated on line, the accuracy of the measurement system can be clearly known, the indication value errors of all points of the pressure transmitter can be intuitively obtained, and the system calibration has practical significance.
