Key Features & Benefits
- Wide Linear Range: 1.5 mm (60 mils) ensures accurate proximity measurement.
- Extreme Temperature Tolerance: Operates from -52°C to +177°C.
- Robust Armor: Stainless steel armor protects against physical damage.
- Low Resistance: Center conductor 0.220 Ω/m for stable signal.
- High Capacitance: 69.9 pF/m typical for reliable data transmission.
- Flexible Field Wiring: Supports up to 305 m cable length.
- Gold-Plated Connectors: Ensure corrosion-free, low-loss connection.
Installation & Compatibility
Length Matching: Cable length + probe length must equal Proximitor total length.
Field Wiring: Use 3-conductor shielded triad cable (18-23 AWG with ferrules).
Compatibility: Works with 3300 XL NSv Proximitor Sensors and monitors.
Diagnostics & Frequency Response
Refer to Figure 16 & 17 for high-frequency rolloff with longer field wiring.
Typical signal output: -1 to -13 Vdc over linear range (10 to 70 mils).
Typical Applications
- Vibration monitoring in turbines and compressors.
- Shaft displacement measurement in generators.
- Position sensing in heavy industrial machinery.
- Critical rotating equipment protection.
