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.

Configure, parameterize, and diagnose hydraulic valves with digital on-board electronics, OBED. It has never been easier to configure hydraulic valves, optimize performance, check status, and get plain text error messages. Connect to onboard digital electronics on Bosch Rexroth hydraulic valves with Bluetooth using the easy2connect app. This simplifies commissioning and increases productivity. The easy2connect app allows you to establish a Bluetooth connection to the OBED digital controls in Bosch Rexroth hydraulic valves from smartphone or tablet. Valves require a Bluetooth dongle for communication (VT-ZBT-1-1X). This can be included with valve or added in the field. The communication adapter displays operating status LED's (red/green) and turns blue while communicating over Bluetooth. Valves identify themselves to the app. View the electronic nameplate (model code, material number, software, firmware). Check operating temperature of electronics and operating hours. Monitor Status and errors displayed in plain text, like Cable Break. Login (or create password) for full access to easy2connect features. See internal command values, actual output values, configure analog I/O signal and range. Set Controller options for application setup. The patented slider bar allows you to adjust sensitivity between moderate and aggressive to optimize dynamics when actively using closed loop pressure control. Experts can enter individual parameters for Proportional, Integral, and Active Damping, as desired. OBED models with IO Link (L1 option) display IO Link status and all master information. The Sensor screen configures pressure sensor, signal type, and operating range. Save changes in a file on handheld device when finished with commissioning. Import a setup from your OBED valve, or export parameters from a saved file to duplicate settings in a spare valve for easy replacement.
