Communication, calibration and HART devices

Asset Management Q&A

Hi. I have a question about HART communicators and devices. Can you help? What's the difference between communication and calibration?

Expert’s answer: Communication, Calibration and HART Devices

Hi there, let me explain the difference between communication, calibration and HART devices.

So, communication means making a connection between a device and a control system to send data, and calibration means checking a device’s ability to measure against a set of technical standards.

You need to compare the calibration range of your device with the standards. If your measurements are out of the standards, then you probably need either zero or span adjustments. Overall, as for communication and calibration, for HART devices and people – both important!
