Analog electronic process transmitters typically have only two calibration adjustments: one for zero and another for span. Occasionally you may find an analog electronic transmitter with a third adjustment: one...
The following instructions describe how to configure a 2 wire Radar smart transmitter with HART communicator using an Emerson 475 Field Communicator. The 475 Field Communicator used for this article...
A sensor is an input device that provides a usable output in response to the input measurand. A sensor is also commonly called a sensing element, primary sensor, or primary detector....
The concepts of calibration (trimming) and ranging are often difficult for new engineers of instrumentation to immediately grasp. A simple analogy useful for understanding these topics is that of setting...
The term “calibration” in the context of smart/intelligent transmitters is often misunderstood. The information provided here serves to explain the difference between sensor trim, range setting, and current trim. Plants...
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...
