Overview

DC351 vibration sensor: can be used to measure the vibration of bearing seats, casings, or structures. This type of sensor measures vibrations relative to free space vibrations, and its output voltage is proportional to the vibration velocity, hence it is also known as a velocity based vibration sensor. The velocity can also be integrated and converted into displacement before further processing. This measurement can evaluate the comprehensive working conditions of rotating or reciprocating machinery, and it is directly installed outside the machine, making it extremely convenient to use and maintain.

DC351 vibration sensor
It is a vibration velocity sensor that uses the principle of magneto electric induction to convert vibration velocity signals into voltage outputs. Its performance indicators are as follows:
(1) Sensitivity: 200mV/cm/s ± 5%
(2) Frequency response range: 10Hz to 1000Hz (-3dB)
(3) Linear amplitude:<3%
(4) Large measurable displacement: 1mm (single peak)
(5) Operating temperature: -30 ℃~120 ℃
(6) Working position: both vertical and horizontal
(7) Environmental conditions: dustproof, moisture-proof, oil proof
Using the principle of magneto electric induction to convert vibration signals into electrical signals. It is mainly composed of magnetic circuit system, inertial mass, spring damping and other parts. 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 the magnetic field lines and generating induced voltage in the coil. The voltage value is proportional to the vibration speed value. Paired with secondary instruments, it can display the magnitude of vibration velocity or displacement, and can also be transmitted to other secondary instruments or AC voltmeters for measurement.
