WitMotion WTVB01-485 Industrial 3-Axis Vibration Sensor, RS485, IP68, 030,000 m Displacement, 0100 mm/s, Multi-node (32) Monitoring

Description

Overview

WitMotion WTVB01 is a compact industrial vibration sensor for real-time condition monitoring of rotating machinery (pumps, fans, motors, engines, water towers, generators, centrifuges, etc.). It measures 3-axis vibration metrics (velocity, displacement, amplitude; plus angle/frequency views) and temperature, applies digital filtering, and streams data to PC software or the Android app for curve display, calibration, configuration, and data logging.
Three hardware formats are available:

• WTVB01-485: RS485 daisy-chain, up to 32 devices on one bus; IP68 waterproof/dustproof aluminum housing.

• WTVB01-BT50: Bluetooth LE, 50 m wireless range, multi-connect up to 4 sensors in the WitMotion Android App; Type-C charging/data cable included.

• WTVB01M (module): TTL serial module version for integrating into your own PCB/MCU.

Key features

• 3-axis measurement with digital filtering; real-time graphs, data lists, raw data, and trajectory/Matlab-style plots.

• Metrics: vibration speed (0100 mm/s), displacement (030,000 m), amplitude (0180), time and temperature; software views include frequency/angle/acceleration/angular velocity.

• Industrial networking: RS485 multi-drop (32 nodes) or BLE multi-connect (4 nodes).

• Rugged: IP68 waterproof & dustproof (485 version); works under splash/rain and can operate in water for up to 10 h.

• Easy install: magnetic base (48 mm, radius 24 mm, thickness 9.41 mm, up to 70 kg suction) or threaded mount (M81.25).

• Developer-friendly: PC software + Android App, manuals, protocol & serial driver, sample code for C++/Python/Delta PLC/STM32.
