The 7 Most Important aspects about Condition, System & Equipment Monitoring

Technology in predictive maintenance is growing fast, and so are Condition Monitoring Solutions, which is one of its most important activities. In particular, the wireless sensors in Condition Monitoring Analysis changed completely the way we approach machinery reliability.

What is Condition Monitoring? What do we need to learn about modern technologies applied in it? Well, I am a Vibration Analysis technology developer, and I invite you to take some time to read these few tips I have written down for you.

What is Condition Monitoring in Vibration Analysis?

Condition monitoring is the process of periodically measuring one or more parameters in machinery to identify significant changes that usually indicate failures in the process or variations in vibration monitoring. It is an essential part of predictive maintenance that allows to plan maintenance actions focused on avoiding failures and their consequences.

For this reason, the condition monitoring process provides enough information to implement pertinent actions upon components that require them.

Condition vibration monitoring is usually applied to rotating machinery such as fans, compressors, pumps, combustion engines, and others.

In Erbessd Instruments we created enough options of condition monitoring systems for you. From low-cost high-capacity equipment, to integral systems with multiple automatic parameters, such as our Phantom® Vibration and Condition Monitoring System.

Analyze machinery performance

You can get tendency graphs of vibration monitoring, current consumption, changes in temperature, and pressure from your machinery. This way, you will know what the behavior trend is for each period. On top of that, you will be able to prioritize the order of condition maintenance. As a result, you will also be able to reduce downtime, and make better decisions about production plans as a benefit of predictive condition maintenance.

Reduce Maintenance cost with a Machine Condition Monitoring System

Some parts, such as gearboxes or bearings can be very expensive to replace, which is why a correct condition monitoring can increase components life span. Remember, condition monitoring is an investment that can pay off in the short term. The Wireless Condition Monitoring Sensor can be an indirect cost reducer.

Increasing production capacity with a condition monitoring system

Maximize your production capacity and make sure you work with reliable operation machines with our condition monitoring system. Design maintenance schedules accurately and create more efficient production plans to guarantee you meet delivery times and keep your customers satisfied.

Monitoring anywhere your are with our wireless condition monitoring system

This system allows you to be away from the company. Some Condition Monitoring systems are as easy as plug & play. Simply put, wireless sensors measure the condition indicator and transmit it to your own database. Now it is possible to have apps and web sites to display monitoring results, not only of a period of time but in real time as well. This can be done from a mobile device, tablet or computer anywhere you are with our online condition monitoring system.

The criticality index of a system is often used to determine the type of condition monitoring solution that needs to be applied to your equipment. This index depends on the following factors:

Economic impact due to an unexpected stoppage
Cost of repair
Environmental impact due to a stoppage
Impact on security for staff
Among others

Criticality index, therefore, divide the machines into 3 categories:

Critical machinery: This type of machinery has the highest hierarchical level within the productive chain. It includes equipment such as power plants and steam turbines that are at the core of the operation. This machinery is vital, and as such, requires a very tight condition monitoring system. These machines are usually monitored by Phantom condition monitoring® system.
Essential Machinery: These machines are an integral part of the production chain, however, in case of an unexpected failure, production will not be affected. Due to their more accessible cost, companies might have replacement systems placed in parallel to avoid production downtimes in case of failure. As the process continues, monitoring the condition of these machines is vital to implement alternative plans at the right moment. Because of this, permanent monitoring systems are the most commonly used in this type of machines as well.
Non-critical machinery: These systems have a minor impact on production and do not usually represent an economic risk for the production chain. Condition monitoring of these machines is considered of low criticality, and a portable system is undoubtedly a good solution.

Economic aspects of Condition Monitoring Solutions

Savings due to production downtime reduction: The most significant savings arising from predictive maintenance are due to the significant reduction in production downtime.

The savings arising from downtime reduction can be calculated through the number of hours of downtime multiplied by the added value per hour for the process.

Cost of downtime = Downtime X $ Value per hour of process

Savings in maintenance costs: Additionally, Savings in maintenance are due to the reduction in man-hours to carry out repairs + savings due to the reduction of unnecessary replacements. This is calculated as follows

$ Savings in Hours = (Man Hours invested in Major Maintenance – Man Hours for minor maintenance) X $ weighted Hour / Man

Condition Monitoring Costs: The costs of condition monitoring systems depend on the chosen system which can be Permanent or Portable. Of course, Permanent systems require more investment if the number of machines is large. On the contrary, Portable systems are cheaper, although, they require a specialist to measure each machine periodically.

The main goal of machinery condition monitoring is to reduce its wear and tear by extending the lifetime of all its components. Either through the reduction of vibration or by improving its temperature conditions, the machine will have a lighter workload and several other benefits.

Electric power consumption: Making a mathematical correlation between vibration and energy is very difficult. Even more so because of the wide variety of machines that exist in a company. However, a study conducted by The Journal of Industrial Technology* proved that any given machine can consume twice as much current as it should only as a result of its vibration. Of course, this study was done in motors that can increase their vibration in such proportions that a big machine cannot replicate; nevertheless, the study does prove a realistic relationship between power consumption and vibration.

Safety and health: The reduction of vibration is closely related to the reduction of noise from a machine and, therefore, reduces the impact on the health of the staff in charge. Prevalence of conditions such as retinal detachment and hearing loss induced by noise can be reduced by applying a correct condition monitoring.

Environmental and Economic Impact. The ecological footprint left by corrective maintenance is considerably greater than that of preventive maintenance, because in the first one, the idea is to replace critical parts as well as lubricating them whether it is needed or not. These actions are intended to avoid stoppages, although they are not always necessary.

Implementing good preventive maintenance actions will not only reduce the environmental impact by avoiding all this waste, but will also have a much lower production cost.

Vibration and condition monitoring process has key aspects to achieve its goals in a short period of time. Nobody knows everything at the beginning of a process, so it is important consider the following advices:

You need to know what you want to measure: It is very important to decide what parameters you want to measure in a machine, as well as what machines you want to monitor. The most important parameters for condition monitoring are vibration, temperature and current.

Establish a starting point: You are probably not an expert analyst, and you don’t need to be either. The first step is to establish a starting point. As far as you are concerned, your machine is working fine right now, so you want to know if that changes. Setting a starting point will let you know when your machine exceeds current values. Over time, through valuable information and experience, you will know each machine’s real limits.

Periodic verification: None of this will work by itself, unless you make checking the status of your machinery and alarms a routine. Erbessd Instruments developed mobile applications, as well as PC and WEB software for you to have a simple way to do it.
