WitMotion WTVB05-485 Tri-Axis Vibration & Temperature Sensor, RS485/CAN, 1–100 Hz, ±16 g, IP67, 5–36 V (Industrial)

Overview

WTVB05-485 is an industrial-grade tri-axial vibration and temperature sensor for online condition monitoring of rotating equipment (motors, pumps, fans, compressors, gearboxes, bearings, etc.). It integrates a high-performance MEMS module with digital filtering, delivers real-time velocity/acceleration/displacement/frequency and temperature data, and supports early-warning analytics in WitMotion PC/mobile software. The metal IP67 enclosure, potting process, and wide 5–36 V supply enable reliable deployment in harsh sites. RS485/CAN dual-interface allows multi-drop cascading of up to 32 devices.
