DygiVib is an app that can save your rotating machinery. You have a doubt about one equipment ? Connect the Dygit1 sensor (distributed by Dynae) and DygiVib will guide you in few steps to define the equipment and its measurement points and to process the tests. Everything is OK ? Just edit the table of levels. A doubt ? Share the file with an expert from Dynae that will post process the raw data and send back the diagnosis. Just set the desired duration of the measurement and DygiVib calculates many indicators in real time: - Global speed level [2 Hz, 5 Hz, 10 Hz - 1000 Hz] in mm / s eff - Overall acceleration level in g eff - Peak signal peak level - 1000 Hz spectrum in mm / s eff - Acceleration spectrum in g eff You will display the chosen indicators in real time but it is also possible to consult remaining data. Il you have selected the ISO-10816 class of your equipment the levels will be automatically colored in green orange or red. All scalars indicators can be exported in CSV file and moreover you can share the database by mail. Raw time signal is exported as DDA file what is the format used by the expert software DynamX® by Dynae. It enables to post process the data to make a diagnosis of the main vibration cause. IMPORTANT NOTE : DygiVib is working with an external digital sensor Digit1. The app will delivery false value without this sensor. File format is DDA format only compatible with DynamX® software. AVAILABLE LANGUAGES English French Italian German REQUIREMENT "Mail" application has to be install to send emails. Contact Dynae (contact.dynae@eiffage.com) for more informations.

Vibration Pro turns your iPhone or iPad into a precision FFT vibration spectrum analyzer — a portable, professional-grade alternative to a benchtop analyzer for predictive maintenance, machinery diagnostics, and vibration research. Version 5.00 is a complete visual redesign: a modern, color-coded interface built around the way vibration technicians actually work, with clean, uncluttered screens for every channel and setting, a drag-cursor readout for reading exact values on any plot, and a crisp new PDF report you can generate and share in seconds. MEASURE FROM ANYWHERE - Built-in 3-axis accelerometer and gyroscope — no extra hardware required - Built-in microphone input for acoustic vibration analysis - Full support for the Digiducer family of professional USB accelerometers (333D01, 333D04, 633A01, 435B39) and The Modal Shop 485B39 two-channel USB input module — mount the sensor on the machine instead of your phone or iPad, for a wider dynamic range and to keep your device off hot, dirty, or vibrating equipment - CTC WS200 and WS300 Bluetooth wireless accelerometers - Sabrent USB input/output dongle support ANALYZE LIKE A BENCH-TOP SPECTRUM ANALYZER - Time series and FFT frequency spectrum on every channel, with adjustable sample rate, sample length, and start delay - Linear-Linear, Log-Log, Log-Linear, and Linear-Log frequency display modes - Hamming, Hanning, and Flattop windowing - Integrate and differentiate in the frequency domain (acceleration ↔ velocity ↔ displacement) - RMS and peak levels per channel and combined - Frequency averaging and peak hold - Color-coded peaks list with the top 5 peaks per channel - Tap-and-drag cursor readout in portrait or landscape, with magnetic snap to peaks - Adjustable frequency alarm limits BUILT FOR THE FIELD - Trigger acquisitions from any channel or the microphone - Auto-repeat and auto-save for long-duration monitoring - Machine Menu — organize test scripts into a visual menu by machine - Save and load complete instrument settings - Full scripting language (subscription) to guide technicians step-by-step through repeatable, multi-point test procedures - Apple Watch companion app to trigger and monitor acquisitions DOCUMENT YOUR RESULTS - New crisp PDF report — identical on iPhone and iPad — with time series and frequency plots, acquisition and sensor details, and a full peaks table - Email data and reports directly from the app, or save locally and transfer with the Files app - Open, non-proprietary format — captures save as plain CSV with full-precision time and frequency data, ready to reload in the app or analyze in Excel, MATLAB, or Python - Automatic reverse-geocoded job location In predictive maintenance applications, Vibration Pro helps identify bearing defects, shaft misalignment, imbalance, and structural resonant frequencies — and is equally useful for monitoring material handling and part-handling equipment, structural testing, and general machinery diagnostics. Scripting is available through an auto-renewing monthly or annual subscription, which can be managed or canceled at any time in your App Store account settings.
