MLV-8 vibration velocity sensors

MLV vibration sensor, MLV series of vibration velocity sensors are part of the inertial sensing. Is the use of magnetic induction principle vibration signal is converted into an electric signal. It mainly consists of magnetic system, inertial mass, spring and damping components. In the sensor housing rigidly fixed magnet, the inertial mass (coil assembly) suspension with spring elements in the housing. When working, the sensor is installed on the machine, the machine vibration within the frequency range of the sensor, coil and magnet relative motion, cutting magnetic field lines, the induction coil which produces a voltage that is proportional to the value of the vibration velocity values. For mating with the secondary instrument to display the vibration velocity or displacement size. Can also be transported to other secondary instrument or AC voltmeter to measure. The overall design of the sensor to use to ensure that it has the following characteristics: its output signal is proportional to the vibration velocity, so it can take care of high-frequency vibration measurement, frequency and low frequency applications, and in line with current international standards (ISO). 1, the rotation of the machine parameters assessment requirements. 2, relative to other types of vibration sensors,, MLV series has a low output impedance sensor, preferably SNR. It is generally the same universal AC voltmeter or oscilloscope can work with, the output plugs and cables are no special requirements, easy to use.
