A facility’s most critical assets may require detailed vibration monitoring around the clock. While semi-critical assets can be monitored with screening sensors, which capture quick snapshots of data to quickly identify potential faults.
Depending on the environment and type of asset, there are many types of vibration sensors to choose from. NCD offers a range of robust, reliable sensors to meet any application need.
Reduce Unplanned Downtime
Vibration sensors play a vital role in predictive maintenance by continuously monitoring equipment vibrations and detecting abnormal patterns. By identifying the onset of problems such as bearing faults, misalignment and imbalance, vibration technology allows maintenance teams to intervene before these issues escalate into costly unplanned downtime or catastrophic failures. This proactive approach aligns with the overall goals of predictive maintenance to minimize unplanned downtime, reduce maintenance costs and optimize equipment performance.
G3Soilworks offers a wide range of wireless vibration sensors that are designed to meet the needs of different industries and applications. These vibration sensor devices can be easily integrated into existing systems, providing valuable information on asset health and helping prevent mechanical breakdowns and other costly production interruptions. Unlike portable vibration meters, these wireless vibration sensors provide continuous data that is automatically analyzed and transmitted to the cloud. By delivering accurate and actionable machine health data, these sensors help businesses achieve a higher Overall Equipment Effectiveness (OEE).
With real-time condition monitoring, technicians can prioritize their time and resources to address the most pressing issues first. This can help reduce unplanned downtime, resulting in improved operational efficiency and profitability for the business. Moreover, reducing the amount of time that technicians spend traveling from asset to asset, taking measurements and conducting maintenance can also improve safety. This is particularly important in facilities where assets are located behind panels, up high or in other hard-to-reach areas.
Lastly, when selecting a vibration sensor, it’s important to consider the sensor’s range and accuracy. The former refers to the sensor’s ability to operate in a variety of conditions and types of machinery, while the latter is about how accurately the sensor can detect vibration frequencies and amplitudes.
For example, a vibration sensor with a wider operating range can be used to monitor fans and other large equipment that produce a lot of noise. On the other hand, a more precise sensor can be used to monitor smaller, faster-moving equipment such as compressors and gas turbines.
Reduce Maintenance Costs
Vibration sensors enable maintenance teams to take action and avoid costly repair work. They can help identify potential problems and prevent equipment failures which will save costs on labor, materials, energy and production. They can also provide valuable insight into machine performance, extending machinery life cycles.
All machines vibrate to some extent, and each has its own characteristic vibration pattern. A change in this vibration signature is a clear indication that a fault may be developing, or it’s about to fail. By monitoring vibration levels and comparing them to previous trends, maintenance technicians can take action to address the problem before it becomes more significant and potentially dangerous for workers.
This can be done either through route-based or continuous online condition monitoring. It is especially useful for critical assets that would represent a large loss in the event of a sudden failure, such as pumps, motors and compressors.
A vibration sensor detects changes in the frequency and amplitude of a machine’s mechanical motion and converts them into an electrical signal, which can then be detected by a vibration analyzer or other electronic device. This information is recorded and stored in a CMMS (computerized maintenance management system). The system uses it to track trends, and the maintenance team receives alerts when the data indicates that an asset may need attention.
Wired and wireless vibration sensors are available for use in many settings. The latter are simpler and cheaper to install and offer a more scalable solution than wired sensors, which can be limited in how they can be placed. They can be used for simple machines like fans and pumps, or even more complex ones like gas turbines or wind turbine gearboxes. They can be mounted with a choice of mechanical fittings including threads, adaptors, quick-fit or glue mounting studs or can be custom designed to suit the application.
It’s important to remember that more data is not necessarily better. Too much data can result in maintenance teams becoming bogged down, and the data may become “noise” that gets tuned out or ignored. It’s therefore essential that maintenance teams set clear priorities for which assets they want to monitor, and only collect the level of data that is needed for their operations.
Increase Productivity
Vibration monitoring provides a valuable insight into machine health. It allows maintenance teams to track patterns and identify potential problems that could lead to failure, allowing them to take action before an equipment breakdown occurs. This proactive approach to maintenance saves companies both money and time, compared to waiting for a repair callout to occur after an equipment breakdown.
Aside from providing a cost-effective way to monitor machinery, vibration sensors also increase productivity by eliminating the need for contractors and reducing unplanned downtime. The use of sensors helps to predict when a machine will reach its limit, so it can be taken offline for routine maintenance at a pre-scheduled date.
When a machine is monitored with a vibration sensor, it will provide a baseline or healthy reading that serves as a reference point for future comparisons. By tracking this information over time, maintenance teams can detect early signs of degradation and act quickly to avoid costly failures.
With a wide range of sensors available, maintenance professionals can choose the right one for their needs. Smaller, less-expensive strain gauges and vibration detectors are ideal for identifying a problem at the first sign of abnormality. Larger, more advanced vibration sensors can capture screening or analysis data, capturing a wider range of frequencies and looking at overall performance trends.
By combining smart, intuitive software analytics and high-speed connectivity technology, maintenance teams can use wireless vibration monitoring sensors to get accurate, real-time information no matter where the asset is located. For water and wastewater plants, where pump and condenser downtime can leave thousands of people without access to clean water, this enables more work to be done in-house.
The sensitivity of vibration sensors can be adjusted, depending on the application and environmental conditions. For example, sensors are designed to operate in extreme temperatures and can withstand dust, moisture and other contaminants found at remote sites. For optimum results, the sensors should be mounted as close to the source of vibration as possible. They should also be properly routed to avoid electromagnetic interference from other devices.
The most effective vibration monitoring programs combine sensors with a CMMS to help prioritize and schedule repairs, based on the severity of any detected issues. However, if too much data is collected and maintenance teams become bogged down with data, the program may not be effective. The key is to select a vibration sensor that is appropriate for the application and ensure that the team knows how to interpret the information and use it to drive maintenance decisions and actions.
Increase Reliability
Keeping equipment working reliably for its intended lifespan depends on an effective maintenance strategy that includes proactive condition monitoring. Vibration sensors are a key component of this strategy, offering the data necessary to understand how a machine is operating and when it is experiencing abnormal patterns that can lead to premature failure. This information empowers maintenance teams to act before damage becomes a major issue, avoiding costly repairs and unplanned downtime.
A vibration sensor is a contactless, electronic device that measures the amplitude and frequency of mechanical vibration. They are placed on machines, such as motors, pumps and compressors, to detect irregularities in a machine’s vibration pattern that can indicate impending faults or imbalance. Faults and imbalances in a machine can cause premature wear and tear, leading to shortened asset life and expensive repairs. Early detection through vibration technology allows maintenance teams to intervene and head off critical machinery failures, saving significant costs.
Vibration sensors work well on a wide range of machines, from fans and water pumps to gas turbines and wind power generators. They are used on machines with rotating shafts, allowing technicians to track issues such as a rotor imbalance or aerodynamic asymmetry in wind turbines, and they can be attached to bearings on conveyor systems, dryer sections (pulp and paper) and ovens and kilns (mineral processing).
With the right vibration sensor, technicians can make fewer trips to assets, reducing wasted time and improving worker safety. Wireless vibration sensors are also available, eliminating the need for cable connections and allowing teams to monitor equipment in hazardous or hard-to-reach areas. Some sensors use a technique called energy harvesting, where they scavenge the heat, light and vibration of their environment to refuel themselves, eliminating the need for batteries.
A good vibration sensor is designed to meet the demands of an industrial setting, with a robust design and durable materials. NCD vibration sensors are engineered to excel in these aspects, with models that can operate across a broad operational range and adapt to different machine categories. They are also rated for temperature and abrasion resistance, making them ideal for harsh environments. They are also ATEX approved and intrinsically safe for operation in potentially explosive environments.
