Instruments having their own pulse beat – that describes the concept of Heartbeat Technology for maximum safety and the highest possible availability. The technology equips instruments with a comprehensive diagnostics and verification concept and also facilitates predictive maintenance. Costs for the provision of evidence for functional efficiency or SIL tests are thus reduced.
Endress+Hauser has expanded its offering in the free space radar market with the addition of the new FMR 60, 62 and 67. These units use frequency modulated continuous wave (FMCW) technology of 80 GHz compared, to the other units 6 GHZ or 26 GHz which are also pulsed frequencies.
The use of the high frequency of 80 GHz brings several advantages to the table. This allows for larger measuring ranges-up to 125 m compared to 70 m of pulse radar technology. Because of the shorter wavelength of the higher frequency this also leads to a more accurate measuring result of up to 0,5 mm. FMCW evaluation with slightly higher dynamic range combined with the narrow beam of the 80 GHz also helps in demanding applications. The addition of these units to Endress+Hauser’s existing Free Space Radar units provides for the best fit frequency for every application.
In addition to the new FMCW technology, Heartbeat Technology, a trend-setting and innovative smart sensor diagnostics and self-test concept, is also introduced. These parameters were available previously but were not as accessible as now with Heartbeat. This saves costs in planning, commissioning and maintenance.
Heartbeat Technology
Endress+Hauser has had Heartbeat Technology since 2012, and this technology has led to rethinking instrument verification. Since then, more safety may be achieved at considerably less cost. The new FMR60, 62 and 67 series already features the preconditions for predictive maintenance and documented verification. This means that every measuring point may be verified and documented in situ without any interruption of the process. A simple, predefined procedure guides the person responsible for maintenance through the verification procedure and, in the end, the verification results are documented in an unambiguous manner. The SIL test according to the safety manual and documentation saves time and reduces costs, too. An automatically generated verification protocol supports the evidence demanded by regulations, laws or plant standards. Heartbeat Technology provides instrument and process data thus facilitating trend recognition for predictive maintenance. The goal is always the optimisation in a targeted manner. Therefore,
a combination of instrument and process parameters provides all of the important information for the next steps in maintenance or process optimisation.
