Bently Performance software module extends functionality of System 1 to include online monitoring of thermodynamic performance. The module fully integrates with the System 1 database and display modules to give users access to comprehensive mechanical and thermodynamic machine-condition information.

Bently Performance executes calculations based on ASME PTC codes, producing key performance indicators:

Actual performance: Actual output for current ambient and operating conditions. This information also indicates the effect of deviation of machine operation from design condition.

Expected performance: Expected output as per OEM curves at design conditions. These values can be compared with actual performance if the machine is operating at the design condition specified by the OEM.

Corrected actual performance: Actual output transposed to standard day conditions (ISO or site-specific rating). When trended, they depict the relative degradation with respect to time.

Corrected expected performance: Expected output transposed to actual operating conditions. These values can indicate conditions like surge or stall.
