Measuring System . All the signals coming into / going out of the control system shall be routed through marshalling cabinets. The input / output modules employed in the control system hall be separate from controlle hardware. . The conditioning and processing functions to be performed as minimum for the analog inputs coming for control and informatio purposes are : - Galvanic isolation of input and output signals wherever required. - Transmitter power supplies with er point fuse protection or current limiting and power supply monitoring. - Monitor sensor break conditions. - Transmitter / transducer si gnal output limit check. - Implementation of multiple measurement schemes. - Square root extraction. - Pressure & temperature compensation. - Online ADC gain and drift monitoring and correction at periodic intervals. - Linearization of the rmocouple signals. - Reasonability check or all analog inputs. All analog signals for control purpose shall be acquired, valid ated; processed and their respective data base updated as per process requirement. For signals required for information only, the above functions shall be per formed at an interval of 1 5 seconds, select able and as decided during det ailed engineering. The validated analog inputs shall be converted int engineering 1 of 1 INDRADHANUSH GAS GRID LIMITED TECHNI
