Quick Detail

Description

The 330904-02-14-05-02-05 3300 NSv Proximity Probe is a precision-engineered, non-contact eddy current sensor designed for superior performance in vibration and displacement monitoring of critical rotating machinery. As a key component of the advanced 3300 NSv series from Bently Nevada, this specific proximity probe configuration is optimized with a distinct 20mm unthreaded length and an extended 140 mm overall case length. This unique geometry, represented by the -02-14- option codes, makes it exceptionally well-suited for applications where the probe must traverse through a thicker machine casing or an insulating spacer before reaching the measurement target, ensuring proper installation and optimal sensing alignment.

This high-performance NSv probe operates on the principle of electromagnetic induction, generating a precise, linear electrical signal that is directly proportional to the gap between its probe tip and a conductive shaft surface. It is engineered to deliver accurate measurements of both dynamic radial vibration and static axial position, providing essential data for predictive maintenance and machine protection. A significant feature of this model is its integrated 5.0-meter (16.4-foot) standard cable, terminated with a secure miniature coaxial ClickLoc connector that includes a protective connector protector. This design ensures a robust, vibration-resistant connection that safeguards against accidental disconnection and environmental contaminants.

Applications

This probe is ideally applied for monitoring radial shaft vibration and position in large industrial equipment such as steam turbines, gas turbines, and multi-stage centrifugal compressors. Its extended 140 mm overall case length with a 20mm unthreaded section is particularly useful when the probe needs to be mounted through a cooling jacket, an insulation layer, or a thick bearing housing bracket to reach the shaft, a common requirement in large frame machinery.

The probe's robust construction and 5.0-meter integrated cable make it suitable for harsh environments in industries like oil & gas and petrochemical processing. It can be reliably used on equipment such as process gas compressors and refinery pumps, where exposure to synthetic lubricants and process fluids is continuous, and where the distance from the measurement point to the junction box necessitates a longer pre-attached cable.

It serves as an excellent solution for retrofit and modernization projects on existing machinery protection systems. Due to its full compatibility with 3300-series monitors and infrastructure, this NSv probe can directly replace older proximity probes on critical assets like turbo-generators and large fans, offering improved durability and performance without requiring changes to the mounting hardware or system wiring architecture.

Specifications

Competitive Advantage

1. Optimized Extended-Length Design for Challenging Mounting Scenarios

The -02-14- configuration provides a specific 20mm unthreaded length and a 140 mm overall case length. This design is a key competitive advantage for applications where standard-length probes are insufficient. It allows the probe to be securely mounted through deeper cavities or protective sleeves in machinery, ensuring the sensing tip is correctly positioned at the target while the connector end remains accessible for easy wiring, solving a common installation challenge in complex mechanical designs.

2. Integrated Long Cable with Protected Connector for Enhanced Reliability

Featuring a factory-integrated 5.0-meter cable with a ClickLoc connector and connector protector, this probe offers significant installation and operational benefits. The generous cable length reduces the need for additional extensions in many cases, simplifying the bill of materials. The protected ClickLoc system ensures a secure, environmentally shielded connection that is highly resistant to vibration-induced loosening and accidental damage during maintenance, leading to higher system uptime and reliability.

3. Robust Performance in Thermally and Chemically Demanding Environments

Engineered with enhanced materials, this probe delivers superior chemical resistance and operates reliably across a wide temperature range (-52°C to +155°C). This combination ensures long-term stability and accuracy in environments where other sensors may degrade, such as in hot compressor stages or in areas exposed to corrosive process fluids. This durability translates to a longer service life, reduced maintenance frequency, and more trustworthy data for condition monitoring programs.
