About

Vibrochecker Pro

This app analyzes vibrations and spectrums using your device's sensors or an external piezo-electronic sensor. It measures and records accelerations, calculates spectral ranges via FFT, and allows data sharing via email. Ideal for technicians needing portable vibration analysis.

Highlights
  • 3-axis vibration measurement
  • Spectrum analysis via FFT
  • Internal and external sensor support
  • Adjustable scanning rates
  • Data saving and email export
  • Variable measuring time and start delay

VibroChecker PRO is a fully-fledged vibration and spectrum analyzer, developed for use on iPhones and iPads. The app uses the optional integrated acceleration sensor or gyroscopes and also allows the connection of an external, high-resolution and professional piezo-electronic sensor (DIGIDUCER 333D01) via the lightning interface. The app is a joint development by the companies ACE Stoßdämpfer GmbH, Fabreeka Inc. and Tech Products Inc. (Kaydon  - Motion Controls Group). The app was designed for external technicians working for Motion Controls and the company’s sales partners. The purchase price is a nominal charge; the external sensor is not included in the price. The light and convenient combination of the high-quality piezo-electronic sensor and the portable vibration and spectrum analyzer on the iPad/iPhone represents an outstanding and extremely easy to transport alternative to existing profile solutions in many applications. The app measures and records accelerations over time and calculates the spectral range using a FFT. The integrated 3-channel acceleration sensor has a sensitivity level of around 0.02g and a range of ± 2g. This sensitivity, with an adjustable scanning rate of 10Hz to 100Hz for the internal sensor and 1kHZ to 16kHz for the external Digiducer, means that the acceleration sensors are capable of measuring vibrations, defective bearings, excitation frequencies of machines and accelerations during material transport in a simple and accurate way. Once the measurement has been completed, the measurement results can be saved or simply sent to your own desktop or to a customer/specialist department using the e-mail function. Some of the core functions include: -  3-axes of measurement -  Variable measuring time -  Variable start delay of 0-20 seconds - Triggering - Selection of scanning rate 10Hz to 100Hz for the internal sensor and 1kHZ to 16kHz for the external Digiducer sensor - Adjustable autorepeat function - Transmission/storage of measurement data by e-mail as a CSV-file

About

Sound Level Analyzer PRO

Read full description

"Sound Level Analyzer PRO" is an integrated sound measurement app featuring a sound level meter and powerful acoustic analysis tools. It is available for a wide variety of applications, such as measuring ambient noise in neighborhoods, testing audio systems, checking interior noise in vehicles, checking sound at live events, and much more. Its advanced sound analysis capabilities allow you to perform real-time frequency spectrum analysis, time-varying level measurement, and in-depth statistical analysis of sound levels. It can also be used to analyze the multifaceted characteristics and trends in the occurrence frequency of any sound source. # Measurement functions Main (Leq): Sound level measurement in real-time. - Sound level measurement (dB): Leq (equivalent sound level), Min (minimum value), Max (maximum value), Avg (time-averaged equivalent sound level) - Frequency weighting correction characteristics: A (general sound level measurement with auditory correction), C (sound level measurement with almost flatter correction than A correction, e.g. peak evaluation at high volume), Z (flat characteristics without auditory correction, physical sound level measurement) - Time weighting characteristics: Fast=0.125 sec, Slow=1.0 sec Power Spectrum (P.S.): View of frequency spectrum analysis in real-time. - Spectrum analyzer function: FFT analysis, 1/3-octave band response analysis. - FFT frequency range settings: 100Hz - 20kHz (FFT All) / 100Hz - 3kHz / 3kHz - 6kHz - Measured value display function in 1/3 oct band response analysis. (OctVal) - Power spectrum display function at the occurrence time of maximum level. (Display Max) Time Course (T.C.): View of time-history of the sound level. (Graphical representation after measuring completion.) - Time-domain fluctuation level display function: up to 8 hours linked on a timer. Statistical Analysis (S.A.): Statistical analysis of sound level at A-weighting and Fast. (Analysis display after measuring completion.) - Histogram: Displays all detected sound level distribution as a percentage. - Percentile Level (LN:dB): Display the levels of L05 / L10 / L50 / L90 / L95 on the percentile level graph. # Control functions - Calibration function: level correction value setting, -20 to +20dB - Measurement timer function: 1 minute / 5 minutes / 10 minutes / 15 minutes / 20 minutes / 30 minutes / 1 - 8 hours (1 hour unit) - Snapshot: Save measurement display with time stamp to Photos. # Examples of usage scenes: - Measure the noise situation in the workplace. - Examine the frequency component and time variation of noise target. - Check the sound level and background noise level during music performance. - To know the sound volume of snoring at sleep. - Measure the quiet characteristics of electric products for the judgment of purchase. - To know the noise level of the car. Also, as a purchase consideration material for automobiles, measure the in-car noise level at the test drive and compare it. - To know the noise situation in my home. Also, when buying a house, knowing the noise situation of the surrounding environment. # Example of the noise level situation: - 130dB: Engine sound of Airplane - 110dB: Horn of Car - 100dB: Noise of passing train - 90dB: In loud factory - 80dB: In the train, Vacuum cleaner - 70dB: Noisy office, Noisy Street - 60dB: Quiet Car, Normal conversation - 50dB: Quiet office - 40dB: In the library, Quiet residential area - 30dB: Outskirts of midnight, Whisper - 20dB: Sounds of rubbing leaves # Note: At the time of the first access to Microphone and Photos after installing the app, you will be asked authorization to access them by the iOS system. If you have not enabled this setting, the app cannot access them by privacy restrictions of the iOS system. Please enable the access permission on the iOS setting, "Settings > Privacy & Security > Photos or Microphone". Please visit our iOS App support page for more information on this app.
