Maintenance and Calibration of HART Field Instrumentation
The field instrumentation in process plants is beginning to come under more sophisticated metrological discipline. Most new field instruments are now smart digital instruments. One popular digital protocol is the HART (Highway Automated Remote Transducer) protocol, which shares characteristics of both analog and digital control systems.
This white paper talks about the maintenance and calibration of HART field instruments. To properly service these instruments, precision analog source/measure capability and digital communication are both required. In the past, this operation required two separate tools-a calibrator and a communicator. Now these capabilities are available in one HART documenting process calibrator.
