Bentley eddy Current sensor system Q&A

Q: Can Bentley's extension cables with different lengths of eddy current probes be interchangeable?

For example, because the 4-meter cable in the original system was accidentally damaged in the process of disassembly, could you replace it with 8-meter spare parts of the same series?

Answer: different series and different lengths of eddy current extension cables are not interchangeable.

Commonly used eddy current probe 3300 xl NSV Bentley, 8 mm and 11 mm, 25 mm, 50 mm and other multiple series and specifications of the probe, in the process of application of different probe is also likely to match with different length of extension cable of 1 meter 9 meters, 5 meters, 7 meters, such as one or several fixed lengths of the system (if the probe with the cable is too long, on the inconvenience when they install the probe).

The impedance of extension cables of different lengths is different (for example, 330130 series of extension cables of 4 meters and 8 meters, the resistance value of probe and cable of each specification can be referred to the probe selection manual).

If swapped, the linearity of measurement will be changed, resulting in a large measurement error

Q: Does the material of different shafts affect the measurement of the eddy current probe? The shaft of the unit in our workshop has a variety of materials, such as 17-4pH, 20CrMo, 2205 duplex steel, 4140 steel, etc., what should be paid attention to in the selection of the eddy current system?

A: Shafting monitoring for a particular material requires Bentley's system selection for that material customization (Mod)

The conventional Bentley eddy current probe system is calibrated and tested with the standard target surface of 4140 steel.

The influence coefficient of different materials on eddy current signal will be greatly different.

The material close to the standard material may have a deviation of 5%-10%, and the larger difference may have an influence of 10%-30% or even no response at all.

Bentley has customized (Mod) standardized products for dozens of common materials used in industrial shafting to maximize measurement accuracy.

Therefore, in the system design of shafting for special materials, it is generally necessary to select the preprocessor or transmitter for Mod selection of this material, so as to avoid measurement errors and unnecessary production losses caused by inaccurate selection

In addition, some customers for special reasons, in the process of maintenance for machine rotor of secondary processing (such as coating, etc.) or don't know if machine shaft material is a standard material, the measuring of the eddy current system are not sure what happens, you can use Bentley's riding shaft verification at the scene of the unit directly to machine shaft for the target in the face of eddy current system linear testing and calibration in detail, and then in the second system (3500) carried out within a certain amount of compensation and correction, the maximum guarantee the accuracy of the measurement.
