Specifications

AE sensor input 2 ch
Number of sample rate settings (setting terminal software) 13 パターン
Conversion cycle (configurable pattern) 11 パターン
Cutoff frequency of low-pass/high-pass filters 0.05, 0.1, 0.25 times the sample rate (normalized frequency)

Description

Inspects vibration waveforms received by an AE sensor and notifies judgment results via the LED on the unit and output signals to control devices. Equipped with a waveform detection filter that extracts abnormal vibration from normal vibration. Settings are configured using PC terminal software; the newly developed setup terminal software divides the setup procedure into six steps and simplifies configuration by limiting sample rate options and displaying guideline amplifier gain values. A newly added low-pass/high-pass waveform detection filter reduces over-detection of normal vibration, confirmed through evaluation.

Features

  • Detects abnormal vibration in a normal vibration environment
  • Extracts abnormal vibration components with waveform detection filter
  • Step-by-step setup screens with setup terminal software
  • Sample rate can be selected directly
  • Guideline amplifier gain automatically displayed
  • Added low-pass/high-pass waveform detection filter reduces over-detection

Applications

  • Tool breakage detection in machining processes
  • Assembly defect detection in assembly processes
  • Abnormality inspection by vibration in production equipment
