Price of Chengdu Digital Acceleration Sensor

The digital accelerometer is an inertial sensorIt uses the principle of magneto electric induction to convert vibration signals into voltage signals, which are proportional to the vibration velocity. Its advantages of high signal-to-noise ratio and low output impedance are widely used. It can be used to measure the vibration of bearing shells or structures (relative to inertial space vibration), directly installed outside the machine, and is extremely convenient to use and maintain.

Principle of Digital Acceleration Sensor

It is fixed on the sensor by two coils, with a magnetic steel in the middle connected to the housing through a spring. The magnetic steel moves inside the coils, thus generating induced electromotive force. This voltage is proportional to the speed of the casing and is called a speed sensor. MVS-2-A04 vibration velocity sensor (magneto electric type with small size, good sealing, and long service life).
Due to the use of a dual coil structure, it can superimpose effective signals, attenuate interference signals, and effectively improve resistance. It is an upgraded mVS-2-A04 vibration velocity sensor from the original SG-1 sensor. The function of the magnetic sensor is to convert the measured rotating machinery into a usable signal output device according to certain rules, convert angular displacement into AC voltage signals, and measure the speed of various magnetic materials such as gears, perforated (or slotted) disks (or shafts), impellers, etc. without contact.

A pulse width modulation signal that can be directly connected to a microcontroller without the need for conventional A/D conversion circuits, with a stable output period and a pulse width (i.e. duty cycle) that changes with acceleration. The acceleration can be measured directly by measuring the duty cycle of the pulse. Convenient to reduce circuit size and improve reliability.
