Important Terms in Calibration
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...
Instrument Zero and Span Calibration
Every instrument has at least one input and one output. For a pressure sensor, the input would be some fluid pressure and the output would (most likely) be an electronic...
