VS8300 Integrated Vibration Sensor

Product Overview:

The VS-8300 series integrated vibration sensor has a wide range of applications, which can be used to measure the vibration of water turbine generators, low-speed rotating machines, engineering buildings, bridges, etc. It can also be used for high-speed machines, such as thermal power generators, fans, pumps, etc. The vibration measured by this sensor is absolute vibration relative to free space. Its output signal is proportional to the amplitude of the vibration.

Basic principle:

The VS-8300 series integrated vibration sensor is an inertial sensor. It utilizes the principle of magneto electric induction to convert vibration signals into electrical signals. It mainly consists of two parts: magnetic circuit system, inertial mass, spring damping and other electromechanical conversion parts, as well as integral amplification and voltage conversion current. A magnet is rigidly fixed in the sensor housing, and the inertial mass (coil component) is suspended on the housing by a spring element. When working, the sensor is installed on the machine. When the machine vibrates, the coil and magnet move relative to each other within the working frequency range of the sensor, cutting magnetic lines and generating induced voltage in the coil. The voltage signal is proportional to the vibration velocity of the measured object. By integrating and amplifying the signal, the displacement signal can be obtained. After passing this displacement voltage signal through a voltage current conversion circuit, a current signal proportional to the same displacement can be obtained.

The overall design of the sensor ensures that it has the following usage characteristics:

1. The sensor has a very low frequency of use and can be applied to low-speed rotating machines.

Compared to other types of vibration sensors, the VS-8300 series integrated vibration sensor has lower output impedance and better reliability

Noise ratio. It can work in conjunction with a general AC voltmeter or oscilloscope. There are no special requirements for output plugs and transmission cables,

Easy to use.

3. The active components with friction have been removed from the sensor design, resulting in a relatively long service life.

4. The sensor has a certain resistance to lateral vibration (not greater than 10g).
