THW1713wirelessvibrationSpeed (Intensity)sensor

Overview

THW1713The wireless vibration speed sensor adopts a split design, which is divided into wireless acquisition sensor and magneto electric vibration speed sensorThe microcontroller collects and processes the output signal of the magneto electric vibration velocity sensor, and communicates itpassLPWANWireless communication transmits data to wireless receiving terminals for centralized monitoring. The wireless acquisition sensor is powered by a large capacity lithium-ion battery and designed with low power consumption.

working principle

Magnetoelectricvibration velocitySensors use the principle of magneto electric induction to convert vibration signals into voltage signalsThe voltage value is proportional to the vibration velocity (intensity) value.sensorMainly composed of magnetic circuit system, coil components, spring damping and other partsdocumentform. In the sensor housinginelasticThere are two coil components fixed on the ground,elasticitymagnet steelBuilt into the coilWhen the sensor isTested machine wave vibrationWhen operating within the frequency range, the coil and magnetic steel undergo relative motion, cutting magnetic field lines and generating induced electromotive force,The induced electromotive force generated is processed by filtering and other conditioning circuits to output a relatively stable sine wave voltage signal. This signal is connectedGo to wireless data collectionsensorPerform numerical calculations and convert them 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.
