330910-00-05-50-02-00 Bently Nevada 3300 NSv Probe

330910-00-05-50-02-00 is a Bently Nevada 3300 NSv Proximity Probe, M10×1 armored version.Code breakdown is typically understood like this:

• 330910: Base model for standard mount M10×1 metric threaded probe with armor
• 00: Unthreaded Length Option of 0 mm
• 05: Overall Case Length Option of 50 mm
• 50: Total Length Option of 5.0 meters (16.4 feet)
• 02: Miniature coaxial ClickLoc connector on standard cable, supplied without connector protector
• 00: Agency Approval Option requiring no approvals / standard industrial version

NSv type is mainly for compact machines. You see it a lot on small centrifugal air compressors, refrigeration units, and smaller process gas compressors.

Where space is restricted—counterbore depth, side clearance, rear access—standard 5 mm or 8 mm probes can struggle. This NSv design fits those tighter geometries better.

Also used when shaft size is small, usually below ~51 mm, or when axial target area is limited. Not really a heavy-frame turbine setup, more on compact rotating equipment.

5.0 m system, 1.5 mm linear range.

ASF around 7.87 V/mm (200 mV/mil) on AISI 4140 steel.

DC resistance typically 5.3 ± 0.7 Ω.

Materials: PPS tip, 304 stainless case, 302 stainless armor.

Temperature range from -52°C up to +177°C, so it covers most industrial environments including compressor skids and plant rooms.

Mounting torque is normally 11.3 N·m (100 in·lbf). Max limit 33.9 N·m (300 in·lbf), but most field installs stay around the recommended value.

ClickLoc connector is light-touch only—finger tight is enough. Do not over-torque, usually kept under 0.56 N·m (5 in·lbf).
Over-tightening here is more risk than benefit.
