LPME System CabinetThe LPMS Data Acquisition software is part of the LPME monitors (Loose Parts Monitoring Equipement). The LPME monitors, detects and evaluates metallic loose parts in reactor systems using transient acoustic signal analysis. Acoustic sensors/accelerometers are permanently located at strategic positions on the system being monitored (in direct contact with pipes and vessels), where loose parts are most likely to impact. The sensors detect the impact of any loose parts as they come in contact with the pipe or vessel wall. The sensors detect the mechanical vibration propagating from the point of impact and convert it into an electrical signal that is amplified by the system preamplifier, processed by the Loose Parts Monitor Software (LPMS) and recorded by the Data Acquisition Computer (DAC). The software alerts the operator and control room when a loose part is detected, and provides a user-friendly interface for the operator to analyze the transients, differentiate between noise and impact signals and determine location and impact characteristics.


LPMS Data Acquisition software is based on the ASME OM-S/G-1997 standard.  The software menu interface is user friendly with simple functional viewing screens. Key features include:

  • Manual and automatic modes of operation

  • Audio monitoring of multiple sensors

  • Special waveform analysis display and storage mode

  • Supervisor mode protection and authorization

  • Multiple analysis screens

  • Automatic, built-in system diagnostics
