User-supplied criteria
Traceable Vibration Limit Comparator
Compare one vibration value with warning and action limits from an identified applicable source. Optional baseline arithmetic is shown without invented ISO multipliers.
Comparison with supplied limits
ISO 13373-1:2002, confirmed in 2024, gives general vibration condition-monitoring procedures covering measurement methods/parameters, transducer selection/location/attachment, collection, operating conditions, signal conditioning and monitoring systems. It is not a universal numerical alarm table. ISO 13373-2:2016 addresses processing, analysis and presentation of vibration data.
ISO 20816-1:2016 provides general measurement/evaluation conditions and says quantities/methods must be well defined with limitations understood. Machinery-specific criteria belong in the applicable part. For example, ISO 20816-3:2022 has a specific industrial-machine scope above 15 kW and 120–30000 r/min plus explicit exclusions; it cannot be applied merely from a generic “pump”, “compressor” or “small machine” label.
No diagnosis or shutdown command: reaching a supplied value triggers the action defined by its controlling source and site procedure. A scalar comparator does not identify a fault, predict imminent failure or replace competent review of spectra, phase, process data and measurement validity.
Nikolai Shelkovenko
Nikolai Shelkovenko is a vibration analysis engineer and the founder and CEO of Vibromera. For more than 15 years he has balanced rotating equipment in the field rather than on a test bench: mulchers, industrial fans, crushers, centrifuges, shafts and spindles. That work is what the Balanset instruments grew out of — they were designed as a tool a specialist can carry to the machine and use alone, on site, not as laboratory equipment. Vibromera was founded in 2017 and has been based in Porto, Portugal, since 2023. Development, assembly and support of the Balanset line all happen here. The flagship instrument is the Balanset-1A, a portable analyser for single- and two-plane balancing and for vibration diagnostics. Nikolai is personally involved in customer support, in working through difficult balancing cases and in the development of the software. He works with customers worldwide, in any language.
