DOCUMENTING PROCESS CALIBRATOR

MC4: a compact, easy-to-use documenting process calibrator The Beamex MC4 is a documenting process calibrator. Instrument data can be sent from a computer to the MC4 and calibration results can be uploaded from the MC4 to a computer containing the Beamex CMX calibration software. Being a multifunctional calibrator, the MC4 is suitable for calibrating various process parameters, such as pressure, temperature and electrical signals. High accuracy is one of the important features of the MC4. A standard feature of the MC4 includes an accredited calibration certificate as proof of its accuracy. The...

Advanced features of MC4 Feature Calibration mode The MC4 includes a versatile calibration mode making it easy and effective to create and calibrate process instruments. The MC4 compensates sensor errors because it includes the possibility to record PRT sensor correction coefficients. Error % display When calibrating a transmitter, its output may be displayed in an error % unit rather than in an engineering unit. Error display in input or output units When calibrating a transmitter, the transmitter’s output may be displayed as an error in input or output engineering units. Any measurement or...
