Description：

The Bently Nevada 330105-02-12-05-12-00 is a 3300 XL 8 mm Reverse Mount Proximity Probe used in eddy current proximity measurement systems for monitoring shaft vibration and position in rotating machinery. This reverse mount configuration is designed for applications where installation access is limited and where a conventional probe mounting arrangement may not be practical.

The 3300 XL 8 mm transducer system supports the performance requirements of API 670 regarding mechanical configuration, linear range, accuracy, and temperature stability when used in the appropriate system configuration. This makes the 330105-02-12-05-12-00 suitable for demanding industrial environments where continuous machinery condition monitoring is essential.

Frequently asked questions

Q1: What type of measurement does this probe perform?

A: This probe uses eddy current sensing technology to measure shaft vibration, radial position, axial position, and Keyphasor® reference signals by detecting the distance between the probe tip and the conductive target surface.

Q2: What is the cable length of this probe?

A: The probe includes a 0.5 meter (1.6 feet) integrated cable, which is typically combined with an 8.5-meter extension cable to form a complete 9-meter 3300 XL system.

Q3: What type of connector does the probe use?

A: The 330105-02-12-05-12-00 uses a Miniature ClickLoc coaxial connector with a FluidLoc cable option, which helps improve resistance against oil migration through the cable.

Q4: What is the operating temperature range of the probe?

A: The probe can operate in approximately -52°C to +177°C (-62°F to +350°F) temperature environments.

Product Applications

Chemical plants and oil refineries: Used to monitor shaft vibration and displacement in large centrifugal compressors, axial fans, and reciprocating compressors.

Thermal and hydroelectric power plants: Used to measure clearance, speed, and axial keyphasor in steam turbines, gas turbines, generators, and high-power water pump bearings.

Steel and metallurgical plants: Used to monitor the health status of core moving equipment such as large blowers and blast furnace blowers.

Air separation plants and refrigeration stations: Used for critical safety interlock protection of industrial refrigeration compressors and centrifugal air compressors.
