BENTLY NEVADA 330704-000-030-90-02-00 3300 XL 11 mm Proximity Probe

Description

The BENTLY NEVADA 330704-000-030-90-02-00 3300 XL 11 mm Proximity Probe is a core component of the 3300 XL 11 mm eddy current sensor system, which also includes extension cables and proximitors. As a replacement for the 7200 series 11 mm and 14 mm sensor systems, this probe supports both compact rail and traditional panel mounting, with electrically insulated mounting bases eliminating the need for separate insulation plates. It delivers an output of 3.94 V/mm (100 mV/mil), and its 11 mm probe tip provides a larger linear range compared to the standard 3300 XL 8 mm sensor system, making it ideal for applications requiring extended measurement coverage.

Key features include ClickLoc gold-plated copper connectors that lock in place to prevent connection loosening, and a CableLoc cable design that can withstand 330 N (75 lbs) of pull force. Multiple probe mount options are available, including armored and non-armored versions with thread types such as 12-20, 58-18, M14×1.5, and M16×1.5, with back-mounted models using 38-24 or M10×1 standard threads.

Designed for frequency ranges from 0 to 8 kHz, the system is used to measure rotor and casing vibration, velocity, acceleration, and displacement in large rotating equipment. Typical applications include radial and axial displacement measurement, steam turbine differential expansion, reciprocating compressor piston rod displacement, tachometer, and zero-speed measurement, suitable for power plants, metallurgy, petroleum, and chemical processing facilities. It also offers enhanced radio interference resistance to simplify installation.
