What is condition monitoring system?
Condition monitoring (CM) is a maintenance approach that predicts machine health and safety through the combination of machine sensor data that measures vibration and other parameters (in real-time) with state-of-the-art machine monitoring software.
How do I choose a vibration sensor for my motor?
As a rule of thumb, if the machine produces high amplitude vibrations (greater than 10 g rms) at the measurement point, a low sensitivity (10 mV/g) sensor is preferable. If the vibration is less than 10 g rms, a 100 mV/g sensor should generally be used.
What are the instruments used in condition monitoring?
What Instruments Are Used in Condition Monitoring?
- Accelerometers for vibration analysis.
- Velocity sensors for vibration analysis.
- Infrared cameras for temperature.
- Ultrasonic sensors.
- Oil quality sensors.
Why is condition monitoring used?
The use of condition monitoring allows maintenance to be scheduled, or other actions to be taken to prevent consequential damages and avoid its consequences. Condition monitoring has a unique benefit in that conditions that would shorten normal lifespan can be addressed before they develop into a major failure.
How many types of vibration sensors are there?
There are three main types of accelerometers: piezoelectric, piezoresistive, and capacitive MEMS.
What is the benefit of vibration monitoring?
Vibration screening allows teams to triage the health of assets; analyze and diagnose the identified asset; and perform the right corrective action at the right time. Installing the Fluke 3561 FC Vibration Sensor on equipment allows you to spend less time taking manual readings and more time addressing problems.
What is the difference between accelerometer and vibration sensor?
An accelerometer measures a quality of acceleration, not necessarily vibration. But vibration sensors, which measure a quantity of acceleration and are therefore a type of accelerometer, are by definition accelerometers. A vibration sensor typically contains a piezoelectric crystal element bonded to a mass.
What are monitoring techniques?
Here are some basic monitoring techniques you might use:
- observation.
- talking with people.
- monitoring work performance and output.
- monitoring absenteeism and staff turnover.
- employee surveys (before, during and after the change)
- baseline measuring before and after the change.
- benchmarking with other work units.
What is the first basic step in condition monitoring?
The first step in condition monitoring is to install the monitoring system hardware onto your serviceable equipment. This may require some retrofitting or modification of your existing assets, with different items of equipment requiring different approaches or instrumentation.
What is the range of vibration sensor?
Industrial vibration sensors are suitable for measuring vibrations at medium strengths. These sensors have a sensitivity of 100 mV/g and their typical frequency band ranges from 1 Hz to 8000 Hz. At the lower end of the scale, the so-called seismic vibration sensors are built to detect very weak vibrations.
How are vibrations measured?
A typical vibration measurement system includes a device to sense the vibration (accelerometer), and an instrument to measure the level of vibration. This equipment also has settings for measuring frequency, a frequency-weighting network, and a display such as a meter, printer or recorder.
What is G value of bearing?
Bearings generate vibrations on higher frequencies due to their construction. These vibrations are measured as acceleration in a “g” value. The frequency range of this measurement may vary a lot and you should find out what would be the best for your particular bearing.
What are the three common monitoring methods?
There are three basic categories of monitoring; technical monitoring, functional monitoring and business process monitoring. These are shown in the diagram below. These three categories have a very clear hierarchy.
What is G in vibration sensor?
It describes the conversion between vibration and voltage at a reference frequency, such as 160 Hz. Sensitivity is specified in mV per G. If typical accelerometer sensitivity is 100 mV/G and you measure a 10 G signal, you expect a 1000 mV or 1 V output.
