Endress+Hauser introduces Heartbeat Technology for analytical transmitters
January 31, 2018 By P&PC Staff
Jan. 31, 2018 – Endress+Hauser is offering Heartbeat Technology with its Liquiline CM44 and CM44R transmitters for use with Memosens pH and conductivity sensors.
Endress+Hauser describes Heartbeat Monitoring as minimizing the probability of a sudden breakdown or failure of the measurement point, while helping to define when maintenance may be needed. Monitoring function benefits are sensor health trending, tracking the quality of calibrations and integrating a maintenance timer to ensure optimal sensor performance is delivered, it notes. According to the company, the Heartbeat Diagnostics follows the NE-107 standardized NAMUR-compliant message structure for categorized event severity level with remedy instructions provided for operations or maintenance. 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, says Endress+Hauser, adding that 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 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.
