Today, that has changed. Modern "smart" instruments do not just send a reading—they send a story.

“The old devices were like thermometers with a telephone,” says Marit van den Berg, an instrumentation specialist at a Dutch-based EPC firm. “The new ones are like weather stations. They tell you the temperature, but also the rate of change, the vibration, the internal diagnostics, and whether they themselves are starting to fail.” The buzzword is predictive maintenance . A traditional pressure gauge fails silently. You only notice when the reading drifts—or worse, when a safety valve blows. A modern pressure transmitter with embedded logic, however, can detect a sluggish diaphragm or a blocked impulse line. It sends an alert to the control room: “I am healthy, but my response time has increased by 15%. Recommend cleaning in 72 hours.” veldinstrumentatie

The older generation speaks HART (Highway Addressable Remote Transducer)—a hybrid protocol that superimposes digital data on top of the classic analog signal. It is the lingua franca of retrofit projects. Today, that has changed
