Product Introduction
The part number 330103-00-03-10-02-CN designates a specific configuration within the Bently Nevada 3300 XL Proximity Probe System family. This is an eddy-current displacement transducer used for non-contact vibration and position monitoring. The suffix codes provide specific details:
-00-03: Often indicates a 5-meter (16.4 ft) standard cable length.
-10-02: Typically specifies a particular probe tip style and mounting thread (commonly an M10 x 1.0 threaded body).
-CN: Usually signifies a "China" regional variant or a specific market configuration, which may relate to packaging, documentation, or minor manufacturing specs.
This assembly is a complete, pre-calibrated kit for direct installation, providing a gap voltage signal to monitoring systems like the 3500 series.
Technical Parameters & Specifications
| Parameter Category | Specification |
|---|---|
| Product Line | Bently Nevada 3300 XL nsV Proximity Transducer System |
| System Components | One proximity probe, one integrated 5-meter extension cable, and one proximitor (driver). |
| Measurement Type | Non-contact, eddy-current displacement. |
| Probe Diameter | 5 mm (0.197 inches) – A smaller probe for space-constrained applications. (Implied by the root number 330103). |
| Probe Mounting Thread | M10 x 1.0 mm (as commonly indicated by -10-02). |
| Sensitivity (Calibrated) | -7.87 V/mm or -200 mV/mil (± 2%), calibrated for a mild steel (AISI 4140) target. |
| Linear Range | Approximately 0.25 to 2.3 mm (10 to 90 mils) from the probe tip. |
| Frequency Response | 0 to 10 kHz (± 3 dB). |
| Target Material | Ferrous steel (AISI 4140). Requires compensation for other materials like stainless steel. |
| Output Signal | DC voltage (Gap Voltage) for average position; AC voltage for dynamic vibration. |
| Power Requirement | Typically -24 VDC from a compatible monitor (e.g., 3500 series rack). |
| Operating Temperature | Probe: Up to 177°C (350°F). Cable & Proximitor: Up to 120°C (248°F). |
| Total Cable Length | 5.0 meters (16.4 feet) (as indicated by -00-03). |
| Connector | Standard Mil-C-5015 or equivalent. |
| Dimensions & Weight | Probe Dimensions: ~ Ø5mm sensing tip with M10 x 1.0 threaded body. Typical length ~ 30-40mm. Proximitor Dimensions: ~ 80mm L x 40mm W x 25mm H. Approximate Total Weight: 0.8 - 1.0 kg (1.8 - 2.2 lbs). |
| Key Feature | The 5mm probe and M10 thread make it suitable for installations with limited radial or mounting space. |
Application Scenarios
This 5mm probe system is designed for applications where space is at a premium or for monitoring smaller diameter shafts. Its "CN" variant suggests common use in projects and facilities within the Chinese market.
Small to Medium-Sized Turbines & Compressors: Monitoring radial vibration on smaller steam turbines, expanders, or compact compressors where larger 8mm probes cannot be physically accommodated.
High-Speed Machinery: Often used on high-speed pumps, turbochargers, and small gas turbines where the smaller probe tip and assembly are less intrusive and suitable for smaller bearing housings.
Electric Motors & Generators (Medium Power): Vibration monitoring on the drive-end and non-drive-end bearings of motors and generators where mounting space in the bearing cap is limited.
Gearboxes: Installing on gearbox casings to monitor shaft vibration near gears, where probe clearance is a critical concern.
OEM Equipment Integration: Built into original equipment manufacturer (OEM) machinery packages (e.g., compressors, fans) that are designed and manufactured for the Asian/Chinese market, where standardized M10 mounting threads are specified.
Important Note: This interpretation is based on standard Bently Nevada numbering conventions. The exact meaning of "-CN" and the precise thread specification should be verified against the official Baker Hughes Bently Nevada drawing or datasheet for part number 330103-00-03-10-02-CN before procurement and installation.
