Key Technical Specifications & Performance
Linear Measurement Range: 1.5 mm (60 mils), from 0.25 mm to 1.75 mm from the target.
Recommended Gap Setting: 1.0 mm (40 mils) from the target surface.
Sensitivity (Incremental Scale Factor): 7.87 V/mm (200 mV/mil) with a tolerance of +12.5%/-20%.
Linearity (Deviation from Straight Line): Better than ±0.06 mm (±2.3 mils) across the full range.
Frequency Response: 0 to 10 kHz (±3 dB) with up to 305 meters of field wiring.
Probe DC Resistance: 4.2 Ω ± 0.5 Ω for the 1.0-meter cable version.
Target Size Requirement: Minimum 8.9 mm diameter; 13 mm or larger is recommended for consistent performance. For smaller shafts, consider 3300 XL 8 mm Proximity Probes.
Physical Construction & Environmental Ratings
Probe Tip Material: Chemically resistant Polyphenylene Sulfide (PPS).
Probe Case Material: Durable AISI 304 Stainless Steel.
Operating Temperature: Wide range from -52°C to +177°C (-62°F to +351°F).
Sealing: Features a Viton O-ring for differential pressure sealing.
Cable: 75 Ω coaxial cable with FEP insulation.
Frequently Asked Questions (FAQ)
Is this probe compatible with my existing system? Yes, the 3300 NSv probe directly replaces the older 3300 RAM probe without modification.
What is the main advantage of the NSv design? It provides significantly increased chemical resistance for harsh environments.
Can I use this for axial measurement on a small shaft? For shafts under 13mm, the scale factor may change. Reducing the gap can help, or review the 3300 XL 8 mm Probes for specialized applications.
How do I order the correct model? Ensure you specify the complete suffix string to get the exact length and connector you need.
