Overview

THW1713 NBiotThe wireless vibration speed sensor adopts a split design, which is divided into wireless acquisition sensor and magneto electric vibration speed sensor. It collects one vibration speed signal and one temperature signal, and is designed with low power consumption,NBiotCommunication method: Connect to the telecommunications IoT platform to achieve remote monitoring of vibration speed and temperature.

working principle

Magnetoelectricvibration velocitySensors use the principle of magneto electric induction to convert vibration signals into voltage signals, which are proportional to the vibration velocity (intensity) value. Sensors are mainly composed of magnetic circuit systems, coil components, spring damping, and other components. There are two coil components fixed in the sensor housing without elasticity, and elastic magnetic steel is built into the coils. When the sensor operates within the frequency range of the measured machine wave vibration, the coil and magnetic steel generate relative motion, the coil cuts the magnetic field lines, generates induced electromotive force, and the generated induced electromotive force is processed by filtering and other conditioning circuits to output a relatively stable sine wave voltage signal. The signal is connected to a wireless acquisition sensor for numerical calculation and processing, and converted into vibration velocity values.

main purpose

Mainly installed on the bearing pads of rotating machinery such as fans, water pumps, and motors, it is used to monitor the operation of the bearings of the tested equipment. It can accurately predict the early stage of bearing failure and avoid further damage to the equipment. It can also be used for various machine tools, CNC center fixtures, vibrating screens, conveyor belt stable operation status, crusher status monitoring and other series of equipment. It can be used to measure the vibration of bearing seats, casings, or structures (absolute vibration relative to inertial space). It is directly installed outside the machine, making it easy to use and maintain.
