SignaTrack™ Quality Assurance System

For production line quality assurance relating to sound and vibration, RH LYON CORP designs, builds and installs turnkey SignaTrack™ systems.

SignaTrack™ Systems are used to:

  • Prevent shipping products that make objectionable sounds
  • Identify assembly defects and diagnose the appropriate corrective action
  • Reduce customer complaints from new products because they sound defective
  • Reduce under-warranty repair costs
  • Improve customer satisfaction
Example applications of SignaTrack™ systems include:
  • Production line testing of motor, gearbox configurations
  • Evaluation of noise emissions from hermetic compressors
  • Sound radiation from household appliances
  • Laboratory audit of automotive components

Though consumers are typically concerned about noise, it may sometimes be better to carry out an equivalent monitoring of vibration levels.  Vibration signals are local and are not readily contaminated by sound in the noisy environment within a plant.  However, establishing an equivalent vibration test requires careful design of the measurement and processing techniques, as well as careful design of the jigs and fixtures.

As part of a SignaTrack™ system design, RH Lyon Corp will:

  • Analyze product signatures to establish pass/fail criteria
  • Work with process engineers to ensure proper production line integration and scheduling
  • Design on-line measurement techniques and procedures
  • Establish data recording and reporting requirements with management
A SignaTrack™ system might include such components as:
  • Motor and brake controls, tachometer
  • Vibration, force or sound sensors
  • Industrial grade computer and display
  • Custom software for test cycling, data acquisition and analysis
  • Data archiving and QA report generation
  • Display outputs, lamps, lights and alarms
  • Push button control inputs
Systems based on the SignaTrack™ architecture can be less expensive, simpler and more capable than systems built around a collection of general-purpose instruments.
