Wireless vibration diagnostic system for rotating machinery

Predicting failures using vibrations


Efficient maintenance of machinery and equipment by failure sign monitoring system for rotating machines

Wireless vibration diagnostic system for rotating machineryWiserot is a wireless vibration diagnostic system for rotating machinery.
It provides vibration data monitoring through a wireless IIoT network.
Utilizing our unique expertise, Wiserot can constantly monitor the vibration of rotating machines operating on production lines and other important equipment, and detect signs of abnormality at an early stage. In addition to being able to prevent breakdowns of individual machines and equipment, our Wiserot system can also be used to formulate equipment replacement plans, leading to a reduction in costs due to production losses.

Your benefits

  1. Early detection of anomalies
  2. Reduced maintenance work and improved safety
  3. Elimination of noise from frequency inverters

By early detection of the unusual movement with trend monitoring after measuring the vibration of rotating machine operated as production line or critical equipment.



FeaturesFeatures vibration monitoring

  • Unique Q-values criteria for early detection of bearing defects to reduce downtime.
  • Reduced maintenance costs through low maintenance and safety measures
  • Our unique diagnostic technology reduces vibration noise from variable frequency drives

System features and functions

  • Battery-powered wireless sensor for easy installation in existing installations.
  • Measurements can be made in locations where wiring is difficult.
  • Trend monitoring by various vibration values (acceleration, velocity, displacement) is possible.



Vibration diagnostic process

Vibration diagnostic process

Introduction of the Wiserot fault prediction monitoring system

simple Diagnostic

  • Daily and periodic monitoring by the system
  • Trend monitoring using various vibration values (acceleration, speed, displacement)
  • Diagnosis using our own criteria values (Q-values)

Detailed diagnosis

  • Identification of abnormal trends
  • On-site precision diagnosis

Repairs and renewals of parts

  • Restoration work carried out
  • Diagnosis of deterioration and determination of remaining life
  • Renewal, replacement, improvement, etc.
