The Bentley preprocessor 330780-50-00 is an eddy-current sensor system preprocessor manufactured by Bently Nevada. Here are the details about this preprocessor:

Product overview

Model: 330780-50-00

Brand: Bently Nevada (Bentley)

Usage: Mainly used for non-contact vibration and displacement measurement of oil film bearing machine.

Main feature

Multiple compatibility: The preprocessor is compatible with a variety of sensor systems, including the 3300 XL 11mm, 3300 XL 8mm, 3300 XL 25mm and 3300 XL 50mm eddy current sensor systems.

Installation flexibility: Compact rail mounting and traditional panel mounting are supported, and both mounting substrates have electrical insulation without the need for separate insulation boards.

Strong anti-radio interference ability: even if installed in the glass fiber shield, it can effectively resist interference from nearby radio signals.

Electromagnetic compatibility: The improved RFI/EMI radiation resistance enables it to meet European electromagnetic compatibility standards without special shielding conduits or metal protective cases.

Technical parameter

Sensor system: 3300 XL 11mm eddy current sensor system, can output 3.94V /mm (100mV/mil).

Measuring range: Thanks to the 11mm probe end, it has a larger linear area compared to the standard 3300 XL 8mm sensor system.

Application field

It is mainly used in measurement scenarios requiring a large linear range, such as axial (thrust) displacement measurement, inclined surface expansion measurement of steam turbines, piston rod displacement or decline measurement of reciprocating compressors, tachometer and zero speed measurement, and phase reference (key phase) signals.

Upgrade and compatibility

The design goal is to replace the 7200 series 11mm and 14mm sensor systems. When upgrading from a 7200 system to a 3300 XL 11mm system, all components need to be replaced with 3300 XL 11mm parts, and the monitoring system needs to be upgraded accordingly. If the 3500 monitoring system is used, an upgraded version of the software configuration is required to be compatible with the 3300 XL 11mm system; The existing 3300 monitoring system also needs to be modified accordingly.

Matters needing attention

Although the terminal and connector of the preprocessor have the electrostatic discharge protection function, you should still pay more attention to electrostatic discharge during use.

It is hoped that the above information can comprehensively and clearly introduce the characteristics and applications of Bentley preprocessor 330780-50-00.
