Basic Knowledge And Working Principle of Mining Vibration Sensor

Mining vibration sensor is currently widely used detection sensors, it is through the internal piezoelectric ceramic sheet and spring counterweight structure to feel the parameters of mechanical movement vibration (such as vibration speed, frequency, acceleration, etc.), and will be converted to an available output signal, through the LM358 operational amplifiers such as amplification, generating control signals due to vibration sensors are also electromechanical conversion devices, sometimes also known as transducers, pickups and so on. . So, here's a look at the basic knowledge and working principle of mining vibration sensors.

Mining vibration sensor is one of the key components in testing technology, with the advantages of low cost, high sensitivity, stable and reliable work, vibration detection of adjustable range, 80% of the current are such sensors.

Mining vibration sensor mechanical reception principle only relative, inertial type two, and electromechanical conversion due to the conversion method and the nature of the different types, a wide range of applications. Modern vibration measurement in the use of sensors in the traditional concept is not an independent mechanical measurement device, but the entire measurement system is a link, and the subsequent electronic circuit is closely related.

Mining Vibration Sensors Basics Principles Vibration sensors are instruments used to measure the amount and frequency of vibration within a given system, device or instrument. These metrics can be used to detect asset imbalances and other issues and predict future failures. Vibration analysis aids in root cause analysis (RCA) when equipment begins to show signs of wear and tear. By monitoring vibration in an asset, the cause of vibration and subsequent damage can be tracked. Vibration monitoring can help with RCA, but it does play a role if predictive maintenance is performed. When connected to a system such as a CMMS, vibration data can be tracked in real time. If dangerously high levels of vibration are seen to be reflected in the data, the need for repairs to the connected asset will be identified.

Mining vibration sensors are connected directly to the asset or monitored via radio. If left unattended, depending on the type of sensor, vibration is detected on the asset in a variety of ways. Over time, the following two types of data are retrieved from the device:

Frequency: 

The data is the frequency or how often the vibration occurs. By tracking the time when a vibration peak occurs on a specific asset, the root cause can be determined.

Intensity: 

The strength of the vibration. The more vibrations obtained from a device, the higher the intensity measurement.

Once both types of data are collected, the CMMS records them in the asset history and uses them as points of comparison. When failures occur, they are reflected in the data, and by comparing current data to past trends, future failures and breakdowns can be predicted.
