The working principle of BENTLY Bentley eddy current probe 330104 is based on the eddy current effect, which is a non-contact electromagnetic induction measurement technology widely used for state monitoring of high-speed rotating machinery, such as high-precision measurement of parameters such as shaft vibration, displacement, and speed.

Core working principle

High frequency magnetic field generation:

A precision coil is integrated inside the probe, and a matching preamplifier provides 1-2 MHz high-frequency AC excitation current, thereby generating a high-frequency alternating electromagnetic field at the probe end face.

Electric eddy current should:

When the electromagnetic field approaches a conductive metal target surface (such as a turbine shaft, commonly made of AISI 4140 steel), according to Faraday's law of electromagnetic induction, a closed vortex current, also known as "eddy current", will be induced on the surface of the target material.

Reaction and impedance changes:

Eddy current itself generates a secondary magnetic field in the opposite direction to the original magnetic field (Lenz's law), while Joule heat loss occurs due to material resistance, resulting in a change in the equivalent impedance (including inductance and resistance) of the probe coil.

Gap signal linear conversion:

The gap (distance) between the probe and the target surface determines the intensity of the eddy current, which in turn determines the change in coil impedance. This change is detected, demodulated, amplified, and linearized by the preamplifier, and finally outputs a DC voltage signal proportional to the gap (typical range: -2V to -18V)

Parameters and series:

Different series of probes have differences in sensitivity, probe diameter, and application scenarios. When selecting, it is necessary to match the requirements of the monitoring system (such as Bentley 3500). ‌‌‌

Corresponding relationship between sensitivity and probe diameter:

7.87 V/mm (200 mV/mil): corresponding to 3300XL 5mm/8mm series probes, such as 330103, 330106, etc. ‌‌‌

3.94 V/mm (100 mV/mil): corresponds to the 3300XL 11mm series probe. ‌‌‌

0.787 V/mm: corresponding to 3300XL 25mm series probes. ‌‌‌

Common series models:

The 3300XL series, such as 330104, 330103, and 330106, is widely used for vibration and displacement monitoring of large rotating machinery such as steam turbines, gas turbines, and compressors. ‌‌‌

The 21000 series, such as 21000-16-10-00-066-03-02, belongs to the eddy current probe housing component and is used for external installation of the probe. ‌‌‌

21811/21812 series: such as M10X1 vibration sensor 21811 and M8X1 vibration probe 21812, with a sensitivity typically of 7.87V/mm. ‌‌‌

System composition:

The Bentley vibration monitoring system consists of three parts: probe, extension cable, and preamplifier. ‌‌‌

The probe operates based on the eddy current effect, where the high-frequency electromagnetic field generated by the head forms eddy currents when approaching the metal conductor, and the gap changes are converted into electrical signals. ‌‌‌
