Description：

The 3300 XL NSv Proximity Transducer system is intended foruse with centrifugal air compressors, refrigerationcompressors, 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 330904-00-12-10-02-CN Proximity Probe used for?

A: The 330904-00-12-10-02-CN is a 3300 NSv Proximity Probe used for non-contact measurement of shaft vibration, shaft position, and displacement in rotating machinery. 

Q2: What does the "12" option indicate in this 330904-00-12-10-02-CN model number?

A: The 12 option specifies an overall case length of 120 mm, making the probe suitable for installations requiring a medium-length probe body.

Q3: What is the total system length of the 330904-00-12-10-02-CN probe?

A: The -10 option indicates a total system length of 1.0 meter (39 inches), including the probe cable assembly.

Q4: What does "Supply Sensitivity Less than 2 mV change" mean?

A: This specification indicates that variations in the power supply cause less than 2 mV change in the probe output, helping maintain stable and accurate measurements.

Product Applications

Oil and Gas (Process Gas Compressors): Widely used in process gas compressors, especially in high-pressure and corrosive process gas environments.

Petrochemical and Refining: Used in turbine compressors in large-scale ethylene and ammonia synthesis plants.

Industrial Refrigeration and Air Compression: Core status monitoring of centrifugal air compressors and refrigeration compressors.

Power Generation and Petrochemical Power: Used for monitoring auxiliary equipment (such as small and medium-sized pumps and fans) and sliding bearing machinery.
