Fieldbus transmitters must be calibrated just like conventional instruments. There are also industrial environments where the calibration of fieldbus instruments should not only be made accurately and efficiently, but also safely. When safety becomes a top priority issue in calibration, intrinsically safe fieldbus calibrators enter into the picture. Many industries require intrinsically safe calibration equipment. Intrinsically safe calibrators are designed for potentially explosive environments, such as oil refineries, rigs and processing plants, gas pipelines and distribution centres, petrochemical and chemical plants, as well as pharmaceutical plants. The Beamex® MC5-IS Intrinsically Safe Multifunction Calibrator is a high accuracy, all-in-one calibrator for extreme environments. Being an all-in-one calibrator, the MC5-IS replaces many individual measurement devices and calibrators. The MC5-IS can also be used for calibrating Foundation Fieldbus H1 or Profibus PA transmitters. The MC5-IS is also ATEX and IECEx certified. The MC5-IS has calibration capabilities for pressure, temperature, electrical and frequency signals. It is a documenting calibrator, which means that it communicates seamlessly with calibration software. Using documenting calibrators with calibration software can remarkably improve the efficiency and quality of the entire calibration process. The MC5-IS also has HART® communication.
