Description
Bently 330106-05-30-05-02-CN
Technical Specifications
- Product Series: 3300 XL 8mm Eddy Current Sensor System
- Probe Diameter: 8 mm (0.315 inches)
- Sensitivity: 200 mV/mil (7.87 V/mm) ± 6.5%
- Thread Specification: M10 x 1 Metric Thread
- System Length: 1.5 meters (5 feet) total system length
Functional Features
- Reverse Mount Design: Specifically engineered for applications where the mounting bracket is inaccessible from the front, allowing installation from the rear side of the bracket.
- High Interchangeability: The probe, extension cable, and proximitor are fully interchangeable without the need for individual bench calibration.
- Regional Compliance: Meets specific domestic regulatory and certification requirements for deployment in Chinese industrial facilities.
Application Scenarios
Widely utilized in power generation, petrochemical, and metallurgical industries. Typical applications include radial vibration and axial displacement monitoring for steam turbines, gas turbines, and centrifugal compressors where front-access mounting is restricted.
Performance Parameters
- Linear Measurement Range: 80 mils (2.0 mm)
- Frequency Response: 0 to 10 kHz (-3 dB)
- Operating Temperature Range: -52°C to +177°C (-62°F to +350°F)
- Supply Voltage: -24 VDC nominal (-17.5 to -26 VDC range)
Material Composition
The probe body is constructed from high-strength, corrosion-resistant stainless steel. The internal coil utilizes premium materials to guarantee exceptional thermal stability and measurement precision across wide temperature ranges.
Structural Characteristics
Features a ruggedized design with TipLoc mold technology ensuring a permanent bond between the probe tip and body. It includes a Viton O-ring for differential pressure sealing and a CableLoc strain relief design capable of withstanding 330 N (75 lbs) of pull force.
Working Principle
Based on the eddy current effect, the probe’s internal coil generates a high-frequency alternating magnetic field. When a conductive metal shaft enters this field, eddy currents are induced, altering the coil’s impedance. The proximitor demodulates this impedance change into a precise voltage signal.
Installation Requirements
The probe must be installed securely in a threaded mounting hole from the rear of the bracket. Initial installation gap voltage must be precisely set within the linear range center (typically -9 to -10 VDC) using a calibrated gap setting tool.
Usage Precautions
Never replace the probe while the system is energized to prevent damage to the proximitor circuitry. Regularly inspect the probe face for metallic debris or oil deposits, and maintain the minimum cable bend radius to avoid internal conductor fracture.
