- System Interchangeability: Fully compatible with standard 3300 XL 8mm probes and extension cables.
Application Scenarios
Extensively deployed in domestic power plants, petrochemical complexes, and metallurgical facilities across China for monitoring rotating machinery.
Performance Parameters
- Frequency Response: 0 to 10 kHz (-3 dB)
- Operating Temperature Range: -40°C to +85°C (-40°F to +185°F)
- Linearity: ±1% of full scale
Material Composition
Housed in a rugged, epoxy-potted aluminum enclosure to provide complete EMI/RFI shielding and environmental protection.
Structural Characteristics
Features standard DIN rail or panel mounting options. Includes secure terminal blocks for field wiring and ClickLoc connectors for sensor interface.
Working Principle
Contains a high-frequency oscillator that drives the probe coil. The demodulator circuit extracts the gap-dependent DC component and the vibration-dependent AC component from the coil’s impedance.
Installation Requirements
Mount in a protected environment, typically inside a junction box or monitoring cabinet. Ensure proper grounding of the enclosure to prevent ground loops.
Usage Precautions
Verify that the Proximitor sensitivity matches the probe specification. Never connect or disconnect the probe while the Proximitor is energized.
