Facilities are assumed to be run normally at all times, but actually it is not “normal.” Periodically diagnosing and maintaining facilities enable the facilities to run normally. “NTN Portable Vibroscope” can easily realize high precision measurement and analysis, contributing to the normal operation of facilities.
Diagnosis of bearing and facility status by just attaching to facilities
High precision measurement and analysis with simple operation
NTN Portable Vibroscope is a device that can measure facility vibrations, and detect abnormalities and damaged positions of bearings. It can be used simply by attaching to the facilities with magnets, screws, etc. Vibration data can be analyzed and managed with Apple iOS smart devices installed the dedicated application.
Measurement / Analysis
Search for the cause of “strange noise” to prevent unexpected situations
- FFT* analysis enables identification of damaged areas of bearings
Display inspection results by presetting the threshold - Acceleration/Velocity/displacement OA* can be measured (Peak and RMS values)
- Approximately 5,500 product numbers of NTN products and other manufacturers’ bearings can also be measured
- *OA= “Over All,” a method to calculate RMS values, peaks, etc. using the entire vibration waveform
- *FFT= A method to analyze the frequency spectrum of the input vibration signal using “Fast Fourier Transform”

Usage Scenario (1)
Facilities with abnormal vibration or strange noise
NTN Portable Vibroscope can be used just only by attaching to the facilities. Facility diagnosis can be performed easily and quickly.
Operation / Communication
Easily operate and analyze by using iPad or iPhone
- Fast analysis by using iPad or iPhone with easy operation (approximately 7 seconds in standard mode)
- High speed communication using Wi-Fi does not need any cables
Usage Scenario (2)
Facilities in hard-to-reach areas
Inspecting air blowers tends to be left at last, as it is located at high areas. It is also difficult to inspect facilities inside the safety covers. NTN Portable Vibroscope can be wirelessly operated by iPad or iPhone, so that it is easy to inspect facilities that are difficult to access and measure.
Data Save
Measurement data can be transferred to PC as it is, so there is no trouble and no paperwork!
- Measurement/analysis data is saved only in iPad and iPhone by registering measurement conditions
- The data in iPad and iPhone can be managed on PC through iTunes
- Trend data is available using measurement history
Dedicated application NTN Portable Vibroscope can be downloaded from App Store for free.
Download of application can be performed from here.
Usage Scenario (3)
Facilities hard to approach from sanitary perspective
Regarding to facilities such as food machinery, the frequency of approaching should be minimized from a sanitary perspective. NTN Portable Vibroscope can measure without approaching such facilities. Moreover, the work of transferring the measurement results written on the paper to the PC can also be eliminated.
