Description
Bently 330703-000-050-10-02-00
Technical Specifications
- Product Series: 3300 XL 5mm Eddy Current Sensor System
- Probe Diameter: 5 mm (0.20 inches)
- Sensitivity: 315 mV/mil (12.4 V/mm) ± 6.5%
- Thread Specification: M6 x 1 Metric Thread
- System Length: 1.5 meters (5.0 feet) total system length
Functional Features
- Compact Footprint: Designed for applications with limited radial clearance or small shaft diameters where 8mm probes cannot fit.
- High Sensitivity: The smaller diameter yields a higher sensitivity, providing excellent resolution for micro-vibration detection.
- System Interchangeability: Fully interchangeable with other 3300 XL 5mm components without individual calibration.
Application Scenarios
Perfectly suited for small high-speed turbines, auxiliary pumps, precision gearboxes, and aerospace test stands where space constraints dictate the use of miniature sensors.
Performance Parameters
- Linear Measurement Range: 50 mils (1.25 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
Material Composition
Constructed with premium 316L stainless steel and high-temperature dielectric materials, ensuring structural integrity and electrical isolation in demanding environments.
Structural Characteristics
Features a streamlined profile with an integrated cable exit that minimizes bending stress. The M6 thread provides secure mounting in small machinery housings.
Working Principle
Operates on the principle of electromagnetic induction. The probe acts as one plate of a transformer, with the conductive shaft acting as a shorted secondary. Changes in gap alter the coupling coefficient, changing the coil’s impedance.
Installation Requirements
Install in a properly sized M6 tapped hole. Ensure adequate clearance around the small probe body to prevent electrical arcing to grounded surfaces. Verify that the total system length matches the proximitor’s calibration specification.
Usage Precautions
Inspect the miniature probe tip for scratches or pitting before installation, as surface damage severely impacts the high-sensitivity signal. Keep the cable away from sharp edges.
