Vibration Sensors vs Proximity Probes for Predictive Maintenance

Predictive maintenance is vital to any industrial operation, as it helps identify potential problems before they become costly. In order to ensure that predictive maintenance is effective, it is essential to have suitable sensors in place to detect potential issues. Two of the most common sensors used for predictive maintenance are vibration sensors and proximity probes. While both of these sensors can detect potential problems, they have different capabilities and applications.

Vibration sensors are used to measure the vibration of a machine or a piece of equipment and can detect early signs of failure. Vibration sensors measure the acceleration and velocity of the vibration, which can be used to determine the machine's condition. Vibration sensors are usually installed at multiple points on the machine to provide detailed information about the vibration in different parts of the device. Vibration sensors are best suited for use with rolling element bearings.

Proximity probes, on the other hand, measure the distance between two objects. They are typically installed to point at a moving shaft and measure the distance between two points as the parts move. Proximity probes can provide information about the speed, position, and direction of motion, allowing operators to detect potential problems before they become serious. Proximity probes are best suited for monitoring journal bearings.

The main difference between vibration sensors and proximity probes is the type of data they provide. Vibration sensors provide information about the vibration of a machine, while proximity probes give information on the motion of a machine.
