Heartbeat tecHnology: More sMart process safety
From the perspective of plant operators, the ideal measuring instrument is completely self- monitoring. With Heartbeat Technology, Endress+Hauser devices come quite close to this ideal, since it relieves operators of most of the effort of monitoring their devices. As a first step, this includes permanent device diagnostics with plain text messages according to NE 107. Heartbeat Technology also renders laborious on-site troubleshooting at the measuring point a thing of the past: When a fault occurs, the revised display turns from green to red and provides clues directly on-site. An app-based operating sequence
guides operating personnel through a device verification process that can be executed at any time (Heartbeat Verification), and the results are recorded in a verification protocol – without interrupting the process or removing the device from the line. The integrated Heartbeat monitoring functions will in future provide additional device and process information obtained from statistical analysis of sensor data or detect undervoltage at any time.
ready for sIl2 and sIl3 applIcatIons
Like their predecessors, the new product lines were developed according to IEC 61508, so they can be directly used in SIL2 or – in homogeneous redundancy – in SIL3 applications. When using pressure transmitters in safety-instrumented process control systems, it is essential for the plant operator to eliminate systematic errors and at the same
checklist pilots follow before take-off. When completing an operating sequence, the user can obtain a PDF test protocol, e.g. via the new Bluetooth interface and the Endress+Hauser SmartBlue app.

time reduce the time spent on each SIL measuring point. The pressure transmitters can be operated without removing the housing lid by means of the touch buttons integrated in the display. This also avoids possible corrosion issues caused by humidity penetrating the device while opening and closing it. The new digital assistants for SIL locking and proof testing according to SIL also help to avoid systematic errors. They provide step-by-step guidance while testing, like the

commissioning of the devices.
Industry 4.0 process sensors open up numerous exciting opportunities for plant operators to make use of the data collected from sensors. The key to success is, however, the transparency and availability of the additional information. “As long as essential sensor data is left sleeping in the pressure transmitter, the potential of Industry 4.0 cannot be realized,” says Peter Dietrich, head of the Department for Digitalisation at Endress+Hauser Germany. “As things stand, 97 percent of all sensor data remains unused. And the Endress+Hauser cloud-based platform Netilion set out to exploit the new-found potential to the full,” adds Dietrich. The free Netilion scanner app makes the
manual inventory of the installed base really easy. The relevant pressure transmitter data can be captured by using either a QR code or an RFID chip. Additional information, e.g. the position of the measuring point, can be entered easily. Netilion Library provides documentation for
the captured pressure instruments at any time, eliminating the previously cumbersome search for relevant documents and significantly reducing maintenance and commissioning times. Meanwhile, the Endress+Hauser data platform holds data sets of more than 40 million installed devices. Netilion Analytics automatically links these
digital twins to the measuring point documents. A dashboard containing all captured measuring points offers a complete overview of the plant, so that the operator can tell at a glance which pressure instruments are no longer available for purchase, for example. Netilion Health, an online service, supports
plant operators with more than 25,000 device diagnostics. The service supplements the pressure transmitters’ status messages with diagnostic codes according to NE 107, error causes and recommended actions – which frees the plant operator from difficult fault interpretation, allowing them to address every fault or error message in a simple and targeted manner.
tHe bottoM lIne: a sMart kIckoff for Industry 4.0
The new Cerabar and Deltabar product lines provide plant operators with a future-oriented start to Industry 4.0. Both proven and newly designed features offer high productivity as well as process safety and plant availability. An investment in digitally optimised processes pays off – today and in the future.
