Test & measurement A
part from temperature and concentration, the measurement parameter “pressure” is crucial in
the process and quality of chemical reactions. Additionally, the pressure built up in containers and pipes is of significant importance when it comes to safety in the chemical process industry, in the oil and gas industry and in power plants. The new Cerabar and Deltabar pressure measurement product lines feature intelligent functions and are designed to meet the safety requirements of these industries. With a broad range of sensors, best possible measuring performance and all the necessary certificates, these instruments can be used in the most demanding pressure measurement applications. The ceramic measuring cell is an example
of a pressure sensor that has already proven itself. The ultra-pure ceramic measuring cell, added to the product range in 1987, shows its full capacity in high-vacuum applications, when aggressive or abrasive media are involved or short-time pressure shocks occur. In addition, it comes with integrated membrane failure detection.
MorE InDusTry 4.0 Process and plant safety are top priorities in the chemical process industry, the oil and gas industry and in power plants. Only when safety is ensured can Industry 4.0 unlock its full potential. In this context, sensors are critically important. Sensors have to reliably capture, link and transfer process data to the respective higher levels – crucial tasks regarding the improvement and efficiency of process management. If ordered with the optional Bluetooth and Heartbeat Technology features, the new Cerabar and Deltabar generations meet all the key criteria mentioned in the NAMUR roadmap for process sensors: these features offer wireless communication and sensor diagnostics and provide sensor and process data.
BluETooTH WIrElEss TECH: DIgITAlly IMprovED proCEssEs for EnHAnCED proDuCTIvITy The Bluetooth interface significantly adds to the ease of use of the new Cerabar and Deltabar product lines. This equally applies to the commissioning and operation of the instruments:
No longer necessary to open the device
Measuring points can easily be operated and configured, even if difficult to access
Device can easily and quickly be parameterised before installation (e.g. in advance in the workshop)
Several PDF reports can be generated directly

Cerabar and Deltabar are ideal companions on the way to Industry 4.0.
Enhanced connectivity, Heartbeat Technology and even more sophisticated features: The
Cerabar and Deltabar pressure transmitters realise the full potential of Industry 4.0.
Future-proof solutions for Industry 4.0
The intelligent functions of the new versions of the Cerabar and Deltabar absolute and differential pressure transmitters pave the way to Industry 4.0 and offer plant operators smart process reliability, as Endress+Hauser’s Alexander Hermann explains
Endress+Hauser Bluetooth interfaces feature
a special protocol (PAKE) that differs from that used by consumer devices such as smartphones or fitness trackers, which means that the Bluetooth connection between the SmartBlue app and a pressure transmitter is not compromised and IT security is maintained. Attacks manipulating the connection between app and device can thus be excluded. Accordingly, the security of Endress+Hauser wireless connection technology received positive ratings from the Fraunhofer Institute for Applied and Integrated Security (AISEC): “In conclusion […] we derive the subsequent evaluation of the security level of the Bluetooth infrastructure: Protocol
high Algorithms high.”
Only personal ID cards with an integrated NFC interface offer a higher degree of security.
