A vibration sensor is a device that converts mechanical motion into an electrical signal. This signal is used to measure the amplitude, frequency, and acceleration of vibrations occurring in operating equipment. They are key in predictive monitoring, as they allow fault modes to be identified before they occur.
The accelerometer is the most common type of vibration sensor. It measures the acceleration of motion in one or more directions and can convert that acceleration into velocity and displacement values through integration. This makes it a versatile sensor for monitoring the condition of rotating machines, motors, compressors, and gearboxes.
Types of Accelerometers
- Piezoelectric: the most widely used in industrial environments. High sensitivity, ideal for monitoring mechanical vibrations.
- Capacitive: used at low frequencies. Lower sensitivity but useful for specific applications.
- MEMS (Micro Electro Mechanical Systems): compact, cost-effective, and low power consumption. Key in wireless sensors for predictive maintenance.
How They Work in Predictive Monitoring
Vibration sensors are installed at strategic points on the asset. They detect changes in vibration patterns caused by imbalance, misalignment, bearing, or gear failures. When vibration exceeds certain thresholds, the monitoring system generates alerts.
In Maper’s case, wireless sensors collect data 24/7 and send it to the cloud, where artificial intelligence algorithms and certified analysts identify faults in advance.
