330910-00-12-10-02-00 Bently Nevada Proximity Probe 3300 NSv

Product Overview

The Bently Nevada 330910-00-12-10-02-00 is a high-precision 3300 NSv proximity probe designed for process compressor applications and machinery protection. This model features an M10x1 metric thread and integrated stainless steel armor for superior mechanical protection in volatile industrial environments.

Compared to the legacy 3300 RAM series, the NSv probe offers significantly increased chemical resistance and enhanced side-view characteristics. With a weight of approximately 150g (depending on configuration), this probe provides a reliable 1.5 mm (60 mils) linear range and is built to withstand extreme temperatures ranging from -52°C to +177°C.

Technical Configuration

Key Performance Features

• Enhanced Chemical Resistance: Specifically engineered for process compressor applications where exposure to corrosive agents is a concern.
• Legacy Compatibility: Fully interchangeable both mechanically and electrically with the Bently Nevada 3300 RAM series.
• Durable Material Science: Features a Polyphenylene sulfide (PPS) tip and an AISI 304 stainless steel case for long-term environmental resilience.
• Precision Signal Integrity: Utilizes 75 Ω coaxial, FEP-insulated cable to ensure a constant Incremental Scale Factor (ISF) of 7.87 V/mm (200 mV/mil).

Installation & Target Data

For optimal axial position or radial vibration monitoring, the recommended gap setting is 1.0 mm (40 mils). The 3300 NSv probe requires a minimum target size of 8.9 mm (0.35 in), though a 13 mm (0.5 in) diameter is recommended to maintain scale factor accuracy. The Viton® O-ring provides a reliable pressure seal between the probe tip and case for differential pressure applications.

Technical FAQs

Q1: Is this probe compatible with older 3000-series 190 probes?
A1: While gapping performance is superior, the NSv is primarily designed as a direct electrical and mechanical replacement for the 3300 RAM series.

Q2: What is the maximum torque for mounting this probe?
A2: For M10x1 threads, the maximum rated torque is 33.9 N•m (300 in•lb). However, finger-tightening is recommended for the initial setup.

Q3: Does the armored cable affect the bend radius?
A3: The minimum bend radius remains 25.4 mm (1.0 in), even with the integrated stainless steel armor, allowing for flexible routing in tight conduit spaces.

Warranty: This product is New & Original and includes a 12-month standard industrial warranty.
