The JM-B-3Z vibrometer vibration speed sensor is an inertial sensor. The vibration signal using the principle of magnetoelectric induction is converted into an electrical signal. 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 assembly) is suspended from the housing by a spring element. During operation, the sensor is mounted on the machine. When the machine vibrates, within the operating frequency range of the sensor, the coil and the magnet move relative to each other, cutting the magnetic field lines, and generating an induced voltage in the coil, the voltage value being proportional to the vibration speed value. Matching with the vibration monitoring instrument, the vibration speed or the amount of displacement can be displayed. It can also be sent to other secondary instruments or AC voltmeters for measurement.
Can be used to measure vibration of the housing, housing or structure. The vibration measured by this sensor is absolute vibration with respect to free space, and its output voltage is proportional to the vibration speed. Therefore, it is also called a speed vibration sensor, which can convert the speed amount into an displacement amount. It is directly installed outside the machine, so it is very convenient to use and maintain. Under some special conditions, it is impossible to install an eddy current sensor for some reason (such as installation conditions and environment). For this type of machine, if the vibration of the shaft can be transmitted to the bearing housing, its vibration. Measurements can be made using a speed sensor mounted on the housing. However, for most of the sliding bearing machines, the shaft vibration is usually attenuated or distorted when it is transmitted to the bearing housing. Therefore, the eddy current sensor is used to directly measure the vibration of the shaft, which is more accurate and comprehensive.
It is an inertial sensor that uses a magnetoelectric induction principle to convert a vibration signal into a voltage signal that is proportional to the vibration velocity value.
The WIN series of vibration speed sensors can be used to measure the vibration of the bearing housing, housing or structure (absolute vibration relative to the inertial space). It is directly installed outside the machine and is extremely easy to use and maintain.
Measuring bearing housing vibration provides meaningful information for comprehensive condition evaluation of rotating or reciprocating machinery.
Machines that can measure the vibration of the housing using a vibration speed sensor include: a machine with a rolling bearing; a plain bearing machine with an oil film.
Performance characteristics:
1. The output signal is proportional to the vibration speed, which can balance the high-frequency, medium-frequency and low-frequency vibration measurement fields, and meet the requirements of the current international standard (ISO) for rotating machine evaluation parameters.
2. Compared to other types of vibration sensors, MLV series sensors have lower output impedance and better signal to noise ratio. It works with a general-purpose AC voltmeter or oscilloscope, and has no special requirements for the output plug and cable. It is easy to use.
3. The sensor has a lower frequency of use and can be used for rotating machines with low speed.
4. The frictional moving element is eliminated in the sensor design, so it is flexible and can measure small vibration (0.01mm).
5. The sensor has a certain resistance to lateral vibration (no more than 10g peak).
Can be used for absolute vibration measurement of the housing, housing or structure relative to free space. The output voltage is proportional to the vibration speed, so it is also called the speed vibration sensor. The output can be the magnitude of the velocity value, or it can be converted into a displacement signal output by integrating the velocity. This measurement allows evaluation of the overall operating conditions of a rotating or reciprocating mechanism.
Mechanically, the common vibration problems of Zui are mostly derived from the rotor. Such as imbalance, misalignment, friction and so on. However, for some machines, the vibration of the shaft is almost completely transmitted to the bearing shell. In this case, the vibration of the bearing shell is measured (measured by a speed sensor mounted on the casing), which can be provided for the comprehensive work of the machine. Meaningful information. These machines include: machines with rolling bearings and machines with oil film sliding bearings.
For most machines, for vibration measurement, Zui is better to use the eddy current sensor, which can directly detect the true vibration of the shaft without contact. However, for various reasons (installation is limited and environmental factors, etc.), it is inconvenient to install an eddy current sensor. For such a machine, if the vibration of the shaft is transmitted to the bearing housing is large enough, the mechanical vibration can be used. A speed sensor mounted on the bearing is used for the measurement.
