Description
Bently 330180-51-00
Technical Specifications
- Product Series: 3300 XL 8mm System
- System Length: 5.0 meters (16.4 feet)
- Mounting Option: DIN Rail Mount
- Agency Approval: Standard (00)
Functional Features
- Superior Anti-Interference: Enhanced RFI/EMI immunity meets European EMC standards, allowing installation inside fiberglass enclosures without signal degradation.
- Versatile Output: Provides linearized voltage or current outputs representing the gap between the probe and the target shaft.
- Short-Circuit Protection: Built-in protection prevents damage during wiring faults.
Application Scenarios
Extensively used for shaft relative vibration, axial displacement, keyphasor, and speed measurement on large rotating machinery such as steam turbines, compressors, and generators.
Performance Parameters
- Sensitivity: 7.87 V/mm (200 mV/mil) ±5%
- Linear Range: 2.0 mm (80 mils)
- Frequency Response: 0 to 10 kHz
- Power Supply: -17.5 to -26 Vdc (without safety barrier)
Material Composition
Housed in a robust A308 aluminum enclosure with electrically insulated mounting substrates.
Structural Characteristics
Compact DIN rail form factor utilizing tool-less terminal blocks for secure and rapid wiring.
Working Principle
Operates on the eddy current principle, generating a high-frequency magnetic field. Changes in the gap between the probe tip and the conductive target alter the coil’s impedance, which the transducer linearizes into a proportional DC voltage.
Installation Requirements
Must be mounted on a standard DIN rail. Ensure the total length of the probe and extension cable strictly equals the 5.0-meter system length.
Usage Precautions
Verify power supply voltage before energizing. Do not exceed the maximum current draw of 12mA.
