Bently Nevada 330709-000-040-10-02-00

Product Introduction This probe is a standard mount 11 mm proximity probe featuring an M16 x 1.5 metric thread without armor. The larger M16 thread provides increased mounting strength for heavy-duty industrial applications. The 40 mm case length offers a compact installation profile while maintaining full 11 mm sensing capability. This probe is designed for axial position, differential expansion, and vibration monitoring on large rotating machinery.

Functional Features The M16 x 1.5 thread is supplied with a 24 mm lock nut and 14 mm wrench flats. The probe features complete interchangeability within the 3300 XL 11 mm system. The patented TipLoc molding ensures robust tip retention. The ClickLoc connector prevents loosening under vibration. The 0 mm unthreaded length means the threaded portion extends fully to the probe shoulder.

Application Scenarios Steam turbine axial position monitoring, gas turbine differential expansion measurement, large compressor shaft vibration monitoring, generator bearing position measurement, heavy industrial pump monitoring, petrochemical reactor agitator monitoring, power plant rotating equipment condition monitoring.

Performance Parameters The Incremental Scale Factor is 3.94 V/mm ±10% including interchangeability over the 4.0 mm linear range. The probe DC resistance is 5.9 ± 0.5 Ω for the 1.0 meter length. Deviation from best fit straight line is less than ±0.10 mm. The system maintains CE mark compliance through enhanced RFI/EMI immunity without special shielding requirements.

Material Composition Probe tip is polyphenylene sulfide (PPS). Probe case is AISI 304 stainless steel. Cable is 75 Ω triaxial with FEP insulation. Connector material is gold-plated brass. The pressure seal is Viton.

Structural Characteristics The probe has a standard forward mount configuration with M16 x 1.5 metric thread. The 40 mm case length provides adequate thread engagement for secure mounting. The 0 mm unthreaded length positions the thread immediately adjacent to the probe tip shoulder. The non-armored cable has a 3.7 mm maximum outside diameter. The probe features pre-drilled safety wire holes in the locknut.

Working Principle The probe operates using eddy current proximity sensing. An RF signal from the Proximitor Sensor creates an electromagnetic field at the 11 mm probe tip. Eddy currents induced in the conductive target surface cause a measurable impedance change. The Proximitor Sensor converts this impedance variation into a DC voltage that is directly proportional to the physical gap between the probe tip and the target surface.
