Calibration Practice For Pressure and Flow Transmitters.
Smart or intelligent transmitters are now the industrial standard for almost all pressure and flow measurement. These transmitters are required to be calibrated regularly to guarantee that they deliver the set measurement objective. What are the recommended calibration practice for these type of transmitters?
Calibration Cycle of a Typical Process Transmitter
Right from when the smart transmitter leaves the factory floor to the plant environment, below is illustrated the typical calibration cycle when applying the transmitters for pressure and flow measurement.
Factory Calibration
Factory calibration is usually done at the factory as part of standard industrial
practice and to conform to relevant standards and codes. A transmitter has an inherent factory Sensor characterization curve similar to the one below:
