When selecting a sensor, consider factors such as measurement range, frequency range, installation method, environmental conditions, and signal output. Bentley Nevada offers a wide range of products to accommodate various application requirements.

How do I calibrate a sensor?

Bentley Nevada sensors often have self-calibration features, but periodic calibration is still recommended. Calibration methods include using a standard vibration source or comparing the sensor to another known accurate sensor.

In-depth: Vibration Signal Analysis

• Frequency Analysis: By applying the Fourier transform, time-domain signals are converted into frequency-domain signals, allowing for the identification of specific vibration frequencies associated with mechanical faults.
• Time-Domain Analysis: Analyzing the waveform of the vibration signal provides information about amplitude, frequency, and phase.
• Envelope Analysis: By demodulating the vibration signal, early fault indicators such as bearing damage or gear wear can be detected.
• Phase Analysis: Comparing the phase relationship between vibration signals from different measurement points can reveal imbalances, misalignment, and other rotating machinery faults.

Case Studies

• Large Generator Vibration Monitoring: Bentley Nevada's vibration monitoring system detected an imbalance in a large generator, preventing a catastrophic failure and ensuring grid stability.
• Pump Vibration Monitoring in Petrochemical Plants: Displacement sensors from Bentley Nevada were used to monitor pump shaft vibration, enabling early detection of bearing wear and preventing equipment downtime.

Working Principles

• Piezoelectric Effect: When a force is applied to a piezoelectric crystal, it generates an electrical charge. This principle is used in many vibration sensors to convert mechanical vibrations into electrical signals.
• Electromagnetic Induction: When a conductor moves through a magnetic field, a voltage is induced. This principle is applied in velocity transducers, where the relative motion between a magnet and a coil generates an electrical signal proportional to the vibration velocity.
• Capacitance Change: Changes in the distance between two conductive plates alter the capacitance. Vibration sensors utilizing this principle measure the variations in capacitance to determine the displacement or vibration amplitude.
