1. Product Overview — Bently Nevada 330980‑50

Product Description

The Bently Nevada 330980‑50 is part of the 3300 XL NSv Proximitor Sensor family, optimized for applications where space, compactness, or restricted geometry demand a thinner profile transducer. The “50” suffix indicates a 5.0 m system length (probe + extension cable + sensor). It is designed to accept a 3300 NSv or 3300 RAM probe + extension cable input and convert that into a voltage output proportional to the displacement. It is used extensively in machinery monitoring systems where tight installation constraints exist.

This NSv variant is often deployed in compressors, small bore shafts, compact assemblies, or where side-view / counter-bore restrictions limit probe geometry options.

2. Technical Specifications

Below is a compiled specification table based on available public information and typical performance of the NSv series sensors:

Notes / Observations:

• One listing of 330980‑50‑CN shows weight 0.24 kg (240 g) and approximate dimensions 7.8 × 6 × 6.4 cm for housing.

• In some vendor descriptions of 330980‑50‑05, the measurement range is quoted in imperial terms (0.1 to 5 inches, i.e. ~2.5 mm to 127 mm) and output signal 4–20 mA or 0–10 V in certain variants (though that may reflect a modified or custom version).

• Standard listings for 330980‑50‑00 indicate the 5 m length and panel mounting, with scale factor typical of NSv systems (7.87 V/mm, etc.).

Because the “50” base variant often comes in “‑00” (no approvals), “‑05” (with approvals), or “‑CN” (regional approvals) sub‑variants, the core mechanical/electrical specs are consistent, only approval, labeling, or mounting slight variations differ.

3. Applications

The 330980‑50 series is used in applications requiring compact or constrained mounting geometry. Typical uses include:

• Small-bore compressor shafts in refrigeration / centrifugal machines

• Vibration / displacement monitoring in tight assemblies where side-view or limited clearance exists

• Axial position / thrust measurement where target faces are small

• Shaft monitoring in compact machines (e.g. small motors, turbomachinery)

• Upgrading older 3300 / 3300 XL or RAM systems in tight installations

• Integration into high-density control panels with limited thickness

Its NSv design permits more flexible probe placement in constrained spaces.

4. Advantages & Key Features

• Compact / Thin Profile: The NSv variant enables installation in tight spaces where standard sensors would not fit.

• Side-View / Counter-Bore Friendly: Designed for installations that restrict side or radial view access.

• Enhanced RFI / EMI Immunity: Thanks to NSv design, the sensor can achieve CE-level immunity without requiring specialized mounting arrangements.

• Compatibility / Interchangeability: Works with standard 3300 NSv / RAM probes, extension cables, and 3300 XL monitoring systems.

• Stable Performance Over Wide Temp Range: With operating range down to –52°C and up to +100°C for some variants.

• Tool-Free Wiring: SpringLoc terminal strips simplify field installation and wiring changes.

• Robust Build: Aluminum housing (A380) provides mechanical strength and longevity.

• Good Load Tolerance: 50 Ω output resistance helps compatibility with many monitoring systems.
