TEST AND CORRECTION DEVICE OF AN INTELLIGENT PRESSURE TRANSMITTER, CAPABLE OF ENSURING THE RELIABILITY OF TEST AND CORRECTION BY ACCURATE PRESSURE CONTROL AND AUTOMATIC DATA ACQUISITION

摘要

PURPOSE: A test and correction device of an intelligent pressure transmitter is provided to save time and labor cost since automatic test and correction are successively performed by a dedicated program.;CONSTITUTION: A test and correction device of an intelligent pressure transmitter(151-155) comprises a terminal(130), a pressure controller(140) and a data acquisition system(160). The terminal comprises a dedicated S/W(131) for automatically testing and correcting the pressure transmitter. The terminal executes the dedicated S/W to successively test and correct targets. The pressure controller receives data for testing and correcting the targets through the communication with the terminal. The pressure controller controls the pressure of the targets to match with the received data. Output value from the targets is converted into digital data to generate measurement.;COPYRIGHT KIPO 2011
