Endress+Hauser offers its new Cerabar and Deltabar pressure and differential pressure instruments, with a Bluetooth interface for easier operation and improved efficiency in regulatory control, safety, and other systems.

A high level of safety combined with enhanced productivity follows the company’s smart safety approach to increase plant availability. Heartbeat Technology creates the data basis for predictive maintenance and allows the instruments’ functionality to be verified without process interruption.

Many industries are struggling with attrition, personnel turnover, and training new hires, and major plant additions are often performed by service providers who may not have a thorough knowledge of the equipment and systems on site. The amount of safety-related equipment continues to grow in many industries, and with it the number of costly required proof tests for maintaining safety integrity level (SIL).

Easy Operation Increases Productivity

To comply with these and other requirements, Endress+Hauser's new transmitters offer a more user-friendly user interface in its new Cerabar and Deltabar pressure transmitters. Intuitive operation is now provided via the SmartBlue app, which includes guided operating sequences for parameterization and commissioning of the pressure sensor, bridging distances of up to 50 feet. Thus, even measuring points that are difficult to reach or in hazardous areas are easy to maintain, even if they are only integrated into the process via a 4–20mA interface.

Plant personnel do not have to connect a cable, and real-time data from the pressure transmitter is easily available without the need for permits to open the housing, or for safety equipment to reach the instrument.

The Bluetooth connection has a special protocol that meets the increased safety requirements in industrial applications, and all connectivity is password protected. The Fraunhofer Institute AISEC tested the interface for its level of cybersecurity protection and rated it "high" for protocol and algorithm.

Unlock your IIoT potential

The NAMUR roadmap "Process-Sensors 4.0" names three key criteria for digital process sensors: wireless communication, sensor diagnosis, and the provision of information about the sensor and the process. With the optionally available Bluetooth and Heartbeat Technology functions, the new Cerabar and Deltabar product lines meet these criteria, providing a solid foundation for implementing an IIoT strategy.
