Vibration Sensors will further solve unnecessary downtime, as well as machine damage which in the long run could end in financial loss.
What are the typical types of vibration sensors & in short, how to pick a vibration sensor?
Definition is Vibration
Firstly, we will explain vibration. Vibration, in short, is a mechanical oscillation encompassing an equilibrium position of a machine; part or merely the back-and-forth motion of a machine & or component.
Ordinarily speaking, vibration in industrial equipment is quite common. However, it can also be a signal of a significant problem.
In machine condition monitoring, we’re dealing with 2 types of vibration, axial (also known as thrust) and radial vibration.
To be specific, axial vibration is a parallel shafting vibration which runs beside the shaft of a motor.
For example, a shaft misalignment could create axial vibration. Radial vibration will happen as a force applied out from the shaft.
There’ll be Radial vibration if the motor is unbalanced; for instance, this will happen if there is a faulty fan blade as well as a bent shaft. Let us now discuss the types of sensors to monitor these kinds of vibration.
Let’s chat about an Industrial accelerometer. Accelerometers are instruments or field sensors that measure velocity & acceleration of oscillation of a structure.
It will have a transducer that transforms mechanical force, caused by vibration or a shift in motion, into an electrical charge using the Piezoelectric effect.
There are 2 types of Piezoelectric accelerometers: high impedance & low impedance.
accelerometers send a signal straight to your measurement instrument. You will find these in laboratories or high-temperature applications.
Low impedance accelerometers have a charge transducer at its front end.
Also as a built-in microcircuit that will transform that charge into a low impedance voltage, this type of sensor easily will interface with conventional instrumentation, which will make it often used in the industry.
Install these permanently if there is a high-risk application.
