Product: 330101-00-13-10-02-00
Category: Proximity Transducer System / Eddy-Current Displacement Probe
Overview:
The 330101-00-13-10-02-00 is a 8mm (≈0.315 in) diameter proximity probe system from the industry-standard Bently Nevada 3300 series. It is designed for non-contact measurement of dynamic vibration and static position of rotating metallic shafts. This specific part number details a complete, factory-assembled system with specific length and connector options. The -13-10-02-00 suffix indicates a 9.5 meter (31 ft) total cable length system, with a 5 meter probe body + 4.5 meter extension, standard sensing range, and a negative-voltage-demodulator-compatible output. It is the most common and versatile size for general-purpose machinery protection.
Key Parameters & Specifications
| Parameter | Specification / Description |
|---|---|
| System Function | Eddy-current displacement measurement for vibration and position. |
| Probe Diameter | 8 mm (0.315 inches) – Standard industry size. |
| Standard Sensing Range | 0.25 to 2.3 mm (10 to 90 mils) from the probe tip. |
| Scale Factor | 7.87 V/mm (200 mV/mil) – The standard sensitivity. |
| Frequency Response | 0 to 10 kHz. |
| Total System Length | 9.5 meters (31.2 feet). This is specified by the -13-10 code, meaning a 5m (16.4 ft) probe integral cable plus a 4.5m (14.8 ft) extension cable. |
| Cable Configuration | Two-Piece System: Probe with 5m integrated cable (330101-00-05-XX) + a 4.5m extension cable (330130-049-XX). |
| Output Signal | -1 to -17 Vdc / 0 to -18 Vdc linear analog signal proportional to the gap. Requires a -18 Vdc to -26 Vdc powered proximitor (e.g., 330180-XX-XX). |
| Target Material | AISI 4140 Steel (or similar mild steel). Must be recalibrated for other materials. |
| Temperature Rating (Probe) | -40°C to +177°C (-40°F to +350°F) for standard version. |
| Connectors | Male Bendix / MIL-C-5015 style connector on the probe cable, mating with a female connector on the extension cable or directly to the proximitor. |
| Mounting | Threaded body for installation in an 11 mm (≈0.433 in) drilled and tapped hole, secured with a standard locknut. |
| Probe Tip | Typically 5 mm diameter sensing coil embedded in a PEEK or ceramic-filled tip. |
| Probe Body Material | Stainless steel. |
| Cable Jacket | High-temperature, oil-resistant, fluoropolymer (FEP/Tefzel). |
| Dimensions (Probe) | Body Diameter: 8 mm x Length (tip to connector): ~5 meters (integral cable). The rigid probe tip section is typically 50-60 mm (2.0-2.36 in) long. |
| Weight (Approx.) | Probe & 5m Cable: ~0.7 kg (1.5 lbs). Full 9.5m System: ~1.2 kg (2.6 lbs). |
Primary Application Scenarios
Radial Vibration Monitoring (Primary Use):
The 8mm probe is the global standard for measuring shaft relative vibration on critical rotating machinery. It is used on virtually all large turbomachinery: Steam Turbines, Gas Turbines, Centrifugal & Axial Compressors, Turbo-expanders, and Large Electric Motors.
Axial Thrust Position Monitoring:
Installed to measure shaft axial movement relative to the thrust bearing collar. This is essential for protecting against catastrophic thrust bearing failure in compressors and turbines.
Differential Expansion & Case Expansion:
Used in pairs or multiples to measure the differential growth between a rotor and its casing during startup and shutdown of large steam turbines.
Eccentricity & Runout Measurement:
Used during slow-roll conditions to establish the mechanical and electrical runout of a shaft, which is critical for obtaining accurate dynamic vibration data.
Key Phasor® Reference:
Very commonly configured as the Key Phasor probe to provide a once-per-revolution timing mark for phase analysis, speed measurement, and balancing. The 8mm size provides robust mechanical strength for this critical timing signal.
Cross-Industry Machinery Protection:
Oil, Gas & Petrochemical: Main process compressors, turbine-driven pumps.
Power Generation: Main turbine-generator sets, large boiler feed pumps.
Marine: Main propulsion turbines and gearboxes.
Aerospace Test Cells: Turbine engine testing.
