Integrated vibration speed sensor

Performance of integrated vibration speed sensor:

To be installed on bearing covers of various rotating mechanical devices, such as turbines, compressors, fans, and pumps.

It is an electromagnetic sensor that outputs voltage by cutting magnetic field lines with a moving coil, and therefore has the characteristics of not requiring power supply during operation and easy installation.

Can be used for measuring the vibration of bearing shells or structures relative to free space.

Its output voltage is proportional to the vibration speed, so it is also known as a speed based vibration sensor.

Its output can be the magnitude of the velocity value, or it can be a displacement signal output by integrating the velocity quantity. This measurement can evaluate the comprehensive working conditions of rotating or reciprocating mechanisms.

The most common vibration problems in machinery are mostly caused by the rotor.

Such as imbalance, misalignment, friction, etc. However, for some machines,

The vibration of the shaft is almost transmitted to the bearing housing. In this case, measuring the vibration of the bearing housing (using a speed sensor installed on the housing for measurement) can provide meaningful information for the comprehensive operation of the machinery. These machines include:

Machinery with rolling bearings and machinery with oil film sliding bearings.

For most machines, vibration measurement is carried out using eddy current sensors,

It can directly and non-contact detect the true vibration of the shaft. However, due to various reasons such as installation limitations and environmental factors, it is inconvenient to install eddy current sensors,

For this type of machinery, if the part of the shaft vibration transmitted to the bearing housing is large enough, the vibration of this machinery can be measured using a speed sensor installed on the bearing.
