HOTSEAT WATER & WASTEWATER ASIA | SEPTEMBER/OCTOBER <strong>2021</strong><br />
CONNECTING PRESSURE<br />
measurement to the future<br />
Endress+Hauser has relaunched its<br />
family of pressure instrumentation<br />
with a focus on simplicity, Industrial<br />
Internet of Things (IIoT) fitness, and<br />
smart sensor technology.<br />
The new Cerabar and Deltabar<br />
pressure transmitters offer intuitive<br />
operation via the SmartBlue app,<br />
which includes guided operating<br />
sequences for commissioning of<br />
the pressure sensor. This is made<br />
possible by an additional Bluetooth<br />
interface, which bridges distances<br />
of up to 25m. Thus, measuring<br />
points that are difficult to reach can<br />
be maintained, even if they are only<br />
integrated into the process via a<br />
4-20mA interface. In addition, the<br />
wizards are also available with DTM<br />
and EDD based tools.<br />
Data from the pressure transmitter<br />
is available at any time. The<br />
Bluetooth connection has a<br />
protocol that meets the increased<br />
safety requirements in industrial<br />
applications. Furthermore, users<br />
can transfer the parameters of the<br />
measuring point when replacing<br />
the electronics via the mobile data<br />
memory HistoROM.<br />
UNLOCKING IIOT POTENTIAL<br />
The NAMUR roadmap, Process-<br />
Sensors 4.0, names three key<br />
criteria for digital process sensors<br />
– wireless communication, sensor<br />
diagnosis, and the provision of<br />
information about the sensor and<br />
the process. The Cerabar and<br />
Deltabar product lines are equipped<br />
with Bluetooth interface and guided<br />
wizards for commissioning, as well<br />
as built-in Heartbeat Technology<br />
function which creates the basis<br />
for predictive maintenance and<br />
allows the devices’ functionality<br />
to be verified without process<br />
interruption.<br />
For instance, Heartbeat<br />
Technology supports maintenance<br />
staff in verifying their measuring<br />
points. This can be done via a<br />
Bluetooth connection and at<br />
the touch of a button with the<br />
SmartBlue app. A verification<br />
protocol, which provides detailed<br />
information about all tests, is<br />
generated automatically. This<br />
basis for this is the continuous<br />
self-diagnostic function of the<br />
pressure transmitters. It achieves<br />
a diagnostic coverage rate of over<br />
95%, Endress+Hauser claimed.<br />
With this information, it is possible<br />
for users to plan system revisions<br />
and maintenance work for<br />
measuring devices in advance and<br />
reduce downtimes, thus simplifying<br />
maintenance processes.<br />
