Endress+Hauser launched Cerabar and Deltabar pressure gauges with a Bluetooth interface to operate and maintain in safety-critical systems. Their level of safety combined with productivity enhancing features is an application of Endress+Hauser’s smart safety approach.
Cerabar and Deltabar operate via the SmartBlue app, which includes guided operating sequences for parameterization and commissioning. The inclusion of an additional Bluetooth interface bridges distances of up to 15 meters. The employee does not have to open the housing or connect a cable. Real-time pressure data is available at any time.
The devices’ functionality can be verified without process interruption – usually in less than three minutes, via Bluetooth using the SmartBlue app. A verification protocol, which provides detailed test information, is generated automatically, based on the continuous self-diagnostic function of the pressure transmitters. It achieves a diagnostic coverage rate of over 95 per cent.
