Description：

The 3300 XL NSv Proximity Transducer system is intended foruse with centrifugal air compressors, refrigeration compressors, process gas compressors, and other machineswith tight installation requirements. The 3300 XL NSv ProximityTransducer System consists of:

a 3300 NSv probe

a 3300 NSv extension cable

a 3300 XL NSv Proximitor Sensor(1)

The primary uses for the 3300 XL NSv Transducer System arefor areas where counter bore, sideview, or rearviewrestrictions limit the use of standard Bently Nevada 3300 and3300 XL 5 and 8 mm Transducer Systems. It is also ideal forsmall target applications, such as measuring radial vibrationon shafts smaller than 51 mm (2 in) or axial position on flattargets smaller than 15 mm (0.6 in). It is primarily used in thefollowing applications on fluid-filmed bearing machineswhere a small shaft or reduced side-view is present:

Radial vibration and radial position measurements

Axial (thrust) position measurements

Tachometer and zero speed measurements

Phase reference (Keyphasor signals)

Frequently asked questions

Q1: What is the Bently Nevada 330903-00-13-10-02-CN used for?

A: The 330903-00-13-10-02-CN is a 3300 XL NSv Proximity Probe used for non-contact measurement of shaft vibration, shaft position, and shaft displacement in rotating machinery.  

Q2: What is the 330903-00-13-10-02-CN Incremental Scale Factor (ISF) of this proximity probe?

A: The 330903-00-13-10-02-CN probe has an Incremental Scale Factor (ISF) of 7.87 V/mm (200 mV/mil), providing a precise relationship between shaft movement and output voltage.

Q3: What is the output resistance of the 330903-00-13-10-02-CN probe?

A: The 330903-00-13-10-02-CN features an output resistance of 50 Ω, supporting stable signal transmission and compatibility with monitoring equipment.

Q4: What is the linear range of the 330903-00-13-10-02-CN?

A: The 330903-00-13-10-02-CN probe provides a linear measurement range of 1.5 mm (60 mils), allowing accurate monitoring within its specified operating range.

Product Applications

Oil and gas, refineries: Vibration monitoring inside bearing housings of high-speed critical centrifugal compressors and natural gas delivery pumps.

Air separation and chemical plants: Due to the typically smaller shaft diameter of centrifugal air compressors (less than 51 mm (2 inches), standard 8 mm probes are prone to lateral effects; this NSv (narrow gap/small target) probe is the industry standard for such equipment.

Power plants: Micrometer-level static measurement of start-up and shutdown speeds (key phase/preamplifier signal) and axial displacement of small steam turbines and industrial feedwater pumps.
