In this study, the comprehensive utilization of computer , communication , and data management technology computer power plant pressure instrumentation calibration system design and development , through a large number of precise experiments , the direct comparison approach parity principle to achieve a pressure indicating instrument , pressure sensor and transmitter computer check of the device , and the system uncertainty analysis , the research results demonstrate the calibration system design and economic ; addition , the modular design and object-oriented programming method , the school inspection software and database management software integrated thermal instrumentation , automatic calibration check data management , including the management of instrument parameters of the pressure gauge, thermocouple , RTD temperature sensor and its transmitter check check management , data management , print management and calibration data query . The final form of a set of portable field line automatic checksum and checksum integrated management is one of the power plant thermal instrumentation automatically check the integrated management system . The system was put into use in the field , running reliable , fully meet the design requirements .
