Machine vibration and predictive maintenance
SimtoLink vibration sensors use a MEMS (micro-electro-mechanical systems) or IEPE (integrated electronics piezoelectric) accelerometer. Frequency response is 0.5Hz～10kHz, and the sensor reports vibration acceleration, velocity, and displacement.
The sensor is for condition monitoring and predictive maintenance on rotating machines, pumps, and fans, with an edge FFT (fast Fourier transform) spectrum. The industrial build stays stable in high temperature, high humidity, and strong electrical noise. Steel, cement, power, and petrochemical sites already use it to move from a fixed overhaul cycle to CBM (condition-based maintenance). Unplanned downtime has fallen by more than 40% on average.
Specifications and interfaces
Several builds cover the sensing principle and the output, so the same family can watch different rotating machines. Typical figures:
| Sensor type | Typical specification | Notes |
|---|---|---|
| MEMS | ±50g, 0.5Hz～10kHz | Modbus straight to a gateway |
| IEPE | Needs a collector | Multi-channel synchronous capture |
| Mounting | M5 thread, magnetic mount | Bearing housing or a rigid point |
| Extra functions | Acceleration / velocity / displacement | Built-in temperature sensor |
Supply is 18～30V DC. Operating temperature is -40℃～85℃. The IEPE type needs a collector. The Modbus type connects straight to a gateway. Acceleration, velocity, and displacement can be switched. A built-in temperature sensor also watches bearing temperature. These figures are typical of the standard model. The product specification governs.
Where it is used, and what changed
From a steel mill to a hydropower station and a petrochemical pump room, the same sensor covers condition monitoring and predictive maintenance. Typical jobs and the results that followed:
Bearing warning on a steel mill
A steel plant fitted 50 vibration sensors on rolling mills, fans, and other critical machines. An edge gateway runs the FFT and flagged a bearing trend 2～3 days ahead, which avoided an unplanned stop.
Turbine maintenance at a hydropower station
A hydropower station watches turbine vibration and runs condition-based maintenance in place of a fixed overhaul cycle.
Pump-room health in a petrochemical plant
A petrochemical pump room uses 80 vibration sensors, with temperature and flow, to build a pump-health model, replace wear parts before they fail, and cut maintenance cost by 30%.
Fan monitoring in a cement plant
A cement plant put sensors on the kiln-inlet and kiln-outlet fans for 7×24 online monitoring and spectrum analysis. Fault-warning accuracy is above 90%.
Selection and installation
- Band and range: A high-frequency fault such as a bearing needs a wide bandwidth. A slow machine can take a low-frequency extension. A harsh vibration site needs an industrial reinforced type.
- Mounting point: Use a bearing housing or a rigid part of the machine. Stay off thin walls and flexible structure. The sensor face has to sit tight against the surface, and bolt torque has to meet the spec.
- How it is mounted: A magnetic mount is for a temporary check. A threaded mount is the one to leave in place, so the vibration actually transfers. For a wireless install, pair it with a SimtoLink LoRa vibration collector.
- Diagnosis: When a reading looks wrong, check the sensor, the cable, and the collector in turn. On a critical machine, use more than one point so the fault location and type are judged together.
- Help on the job: SimtoLink runs vibration-analysis training and diagnosis, and helps build a fault-signature library, alarm thresholds, and an equipment-health system. Selection advice follows once the machine type, point count, and interface are known.
