Product Introduction
The Bently Nevada 330180-50-00 is a 3300 XL Proximitor Sensor used in eddy-current proximity measurement systems. It is factory calibrated for a 5.0 m total system length and configured for panel mounting with a standard 4-hole footprint compatible with earlier 3300 Proximitor installations.
When paired with a compatible 3300 XL 8 mm probe and extension cable whose combined length equals 5.0 m, it delivers approximately 7.87 V/mm (200 mV/mil) sensitivity across the probe’s linear range. The proximitor provides electrical isolation through its mounting base, strong RFI/EMI immunity, and SpringLoc terminal strips for field wiring. The “00” approval code means no special agency approval is specified, so it should be treated as a standard industrial proximitor unless the physical label shows otherwise.

Key Selling Points & Differentiators
- Exact 5.0 m system length. Matches the most common 3300 XL 8 mm channel configuration for API 670-style monitoring.
- Panel-mount footprint. Shares the same 4-hole mounting pattern as legacy 3300 Proximitor sensors, simplifying retrofits.
- Electrically isolated base. No separate isolator plate required.
- SpringLoc terminals. Tool-free, vibration-resistant field wiring connections.
- Strong RFI/EMI immunity. Can be installed in non-metallic housings without degrading signal integrity.
- Drop-in 3300 XL compatibility. Works with standard 3300 XL probes and extension cables without matched-component calibration.
Quality Transparency SOP
- Part number verification. We confirm the label reads 330180-50-00 and matches the 3300 XL Proximitor Sensor family.
- System length check. The “50” code is verified as 5.0 m system length to avoid mismatches with 1.0 m or 9.0 m variants.
- Terminal and housing inspection. SpringLoc terminals, mounting base, and housing are checked for corrosion, cracked terminals, or damaged threads.
- Supply voltage and output check. With a compatible probe and extension cable, we verify supply voltage and gap voltage behavior using a Fluke multimeter.
- ESD-safe packing. The proximitor is sealed in an anti-static bag and foam-packed to prevent terminal or housing damage.
Technical Risk Avoidance
❗ Confirm total system length before installation. This proximitor is calibrated for a 5.0 m system. The probe cable length plus extension cable length must equal 5.0 m. A wrong total length will shift sensitivity and gap-voltage settings.
❗ Verify mounting option. Code “50” means 5.0 m system length with panel mount. If DIN-rail mounting is required, a different variant such as 330180-51-00 may be needed.
❗ Confirm approval requirements for hazardous areas. The “00” code indicates no special agency approval. Do not install in Zone 2 / Division 2 areas unless the physical label and approval drawing explicitly permit it.
❗ Do not mix system lengths. A 5.0 m proximitor must not be used with a probe + extension cable totaling 7.0 m or 9.0 m unless the proximitor is specifically calibrated for that length.
❗ Verify target material calibration. This proximitor is factory calibrated for AISI 4140 steel. If the measured shaft is made from a different material, sensitivity and linear range may change.
❗ Keep terminals clean and properly torqued. Loose or contaminated wiring connections can cause unstable gap voltage, false vibration readings, or monitor faults.
Buyer’s FAQ
Is this a complete vibration sensor? No. This is only the proximitor sensor. A complete measurement channel also requires a compatible 3300 XL proximity probe and 3300 XL extension cable.
Can I replace a 330180-51-00 with this? Not without checking mounting. The -51- variant is DIN-rail mount, while the -50- variant is panel mount. Electrically they are both 5.0 m system length, but the mechanical installation differs.
Can I replace a 330180-50-05 with this? Not without checking approval requirements. The -05 variant carries multi-license approval, while the -00 variant has no special agency approval specified.
Can I replace a 330180-90-00 with this? No. The -90- variant is calibrated for a 9.0 m system length. Using it with a 5.0 m probe + cable combination will produce incorrect sensitivity and gap voltage.
Does this include the probe or extension cable? No. Unless explicitly stated, this listing covers the proximitor only.
Is this genuine Bently Nevada? Yes. We sell genuine surplus inventory. The part number is verified against the physical label before dispatch.
What warranty applies? Standard 12-month warranty against DOA and functional defects. Damage from incorrect system length, wrong supply voltage, wiring errors, or chemical exposure is not covered.
