What do I need to get started for a predictive maintenance (PdM) program?

We talk a lot about planning in implementing maintenance strategies, and predictive maintenance (PdM) programs are no different. In fact, a PdM program might require even a little more planning than some other maintenance strategies because it requires a facility to think critically about the kinds of measurements that provide useful, actionable data about asset health. Some useful tools to get started:

Know what kinds of measurements to gather

It's vital for the longevity and success of a PdM program for a facility to understand the types of measurements it needs to take because the data you gather, much like in a doctor's appointment, are the "symptoms" of the assets. Without useful information, the maintenance team can't take action.

For instance, if an asset doesn't generate much heat or if the asset's heat levels don't indicate a fault, there's no reason to invest in expensive infrared technology. This process requires a facility to look into the proposed predictive assets and determine exactly which measurements (sound, vibration, heat, etc.) it needs to accurately diagnose the health of the equipment.

Invest in data gathering tech

You're going to need sensors and cameras to measure data, but ultimately you need a place for all of that data to go. Investing in rock-solid data gathering technology is a big chunk of a PdM program. It's a good idea to invest in technology with a mobile component as well - this allows technicians and maintenance staff to check asset health on the go.

Use calculation algorithms

Going into a PdM program can be extremely difficult (and sometimes pointless) if you don't understand and use algorithms to track patterns and trends in your assets. These calculations won't be useful right away - after all, the monitoring technology needs some time to build up a history of use and predict future issues - but laying that groundwork will ensure the success of a PdM program.

Get the right sensor equipment

When you know what measurements you need, you can begin to invest in condition monitoring equipment to take those measurements. Here are some particularly common monitoring techniques, so make sure to acquire the proper sensor for that technique:

• Vibration
• Lubricant testing
• Infrared (heat)
• Acoustics (sound)
• Current, voltage

Once you've got these basics down, a PdM program should start to see a defined shape that can help your maintenance team crack down on issues even before they happen.
