Description

The Bently Nevada 330180-X2-05 represents a collective series designation for the high-performance 3300 XL series proximity sensor. In this specific part number syntax, the letter “X” acts as a variable wildcard designating the total system length (1.0 meter, 5.0 meters, or 9.0 meters). Specifically, the internal electronics continuously convert high-frequency radio frequency (RF) eddy-current gap modulations from a probe into a highly accurate, proportional analog DC voltage. Consequently, the unit transmits static and dynamic machinery displacement or vibration data directly to continuous machinery protection racks—such as the Bently Nevada 3500 series—without requiring any on-site field calibration.

Hardware Specifications

Transducer Electronics and RFI Resilience

The Bently Nevada 330180-X2-05 relies on advanced internal circuitry that inherently rejects radio frequency interference (RFI) and electromagnetic interference (EMI). Because the sensor blocks this noise, technicians do not need specialized external metal shielding conduits or isolated enclosure grounding plates when retrofitting older machinery racks. Furthermore, the internal oscillator conditions the dynamic signal to an average scale factor (ASF) of 200 mV/mil over a 2.0 mm (80 mils) linear range. As a result, the hardware maintains strict compliance with the API 670 machinery protection standard.

Frequently Asked Questions

Q: What specific hardware variables do the “X2” and “-05” option codes define?

A: The designation -X2 means that the factory delivers a bare housing with no integrated mounting hardware (omitting the traditional panel ears or DIN-rail clips). However, the first digit X varies based on your total physical cable calibration requirements: 1 (1.0 meter), 5 (5.0 meters), or 9 (9.0 meters). Meanwhile, the option code -05 specifies that the module carries multiple global certifications, including CSA, ATEX, and IECEx approvals for explosive environments.

Q: Can this Proximitor safely mix with older, non-XL Bently Nevada system hardware components?

A: Yes, absolutely. The 3300 XL Proximitor sensor provides complete backwards-compatibility and component interchangeability. Therefore, you can seamlessly pair the 330180-X2-05 sensor series with legacy non-XL 3300-series 5mm or 8mm probes without introducing measurement degradation or scaling imbalances.

Field Installation Guidelines

• Shielding and Ground Isolation: First, connect the coaxial probe or extension cable securely using the integrated, gold-plated ClickLoc connectors. Turn them finger-tight until you hear an audible click. Next, connect the overall outer shield of the field wiring to the terminal block. Finally, maintain single-point instrumentation ground isolation exclusively at the monitor rack panel.
• Mounting Requirements: Because the “2” suffix indicates that the unit lacks pre-installed DIN clips or panel mount tabs, you must install this specific unit inside a specialized high-density component rack frame. Alternatively, secure the sensor enclosure using custom or aftermarket mechanical bracket clamps inside a clean, weather-protected field junction box.
• Linear Gap Calibration: During field commissioning, mechanically gap the proximity probe target surface until the static DC terminal output registers a true center-range voltage measurement of -9.0 VDC. This value correlates to a center mechanical gap of roughly 1.27 mm (50 mils).
