General Introduction

The WT81M smart wireless monitor is a device equipped with an LCD display that integrates vibration, magnetometer, temperature, and audio acquisition functionalities. It is powered by a battery by default but also supports an external power input.

The terminal can connect up to two external sensors, each supporting three-axis acceleration, magnetometer, and temperature. All axial accelerometers and magnetometers achieve high-speed synchronous sampling for a total of 8 axes.

The monitor is embedded with intelligent diagnostic algorithms to predict equipment failures, making it essential for petrochemicals, power plants, and steel mills. It integrates Bluetooth 5.2, 4G, Wi-Fi, and LoRaWAN technologies.
