Endress+Hauser offers Heartbeat Technology with its Liquiline CM44 and CM44R transmitters for use with Memosens pH and conductivity sensors. Heartbeat Diagnostics’ continuous analysis of transmitter/sensor system health status during operation enables recognition of related events when they occur. Heartbeat Diagnostics follows the NE-107 standardized NAMUR-compliant message structure for categorized event severity level with clear remedy instructions provided for operations or maintenance.
心跳监测可以最大程度地减少测量点突然崩溃或故障的可能性，并有助于定义何时需要维护。例如，检测pH传感器中玻璃阻抗增加可能表明玻璃破裂。在电导率传感器中，如果线圈电流超出范围，则可能表明传感器中的短路或折线。监视功能的好处是传感器健康趋势，跟踪校准的质量并集成维护计时器，以确保交付最佳的传感器性能。
Heartbeat Verification permits a measurement point to be assessed at any time in situ, without removing the sensor or shutting down the process. This qualitative function checks the entire measurement loop, verifying sensor and transmitter performance. Verification results are provided via an audit safe report automatically generated by the transmitter. The report is saved in PDF format and can be preserved on an SD card for transfer to a computer. These reports can be used when regulatory, quality or safety documentation is needed.
When the Liquiline transmitter is connected to a PLC, SCADA or distributed control system via fieldbus digital communications, Heartbeat Technology provides the host system with a wide range of sensor information that can be combined with process data to identify trends. This information, along with key performance indicators can be used for process optimization and predictive maintenance. Heartbeat Monitoring information is available over Profibus DP, EtherNet/IP, Modbus TCP or Modbus 485 protocols.
Heartbeat Technology is now available as an option in Liquiline CM442, CM444 and CM448 transmitters and all DIN-rail mount versions, and works with Memosens pH and conductivity sensors, and Liquistation CSF34 and CSF48 samplers. In the future, Heartbeat Technology will be available in Endress+Hauser’s dissolved oxygen, turbidity, nitrate, chlorine sensors and Liquiline System CA80 analyzers. The Heartbeat Technology option can also be added to existing Liquiline transmitters or samplers by the application of an activation code (Requires firmware version 1.06.04 or higher firmware in the Liquiline platform device.)
