330881-00-04-150-06-02 Bently Nevada PROXPAC XL Sensor

Bently Nevada 330881-00-04-150-06-02 PROXPAC XL Proximity Transducer

Key Technical Specifications

• Linear Range: The system measures from 0.25 mm to 2.3 mm (10 to 90 mils). Output voltage spans approximately -1 Vdc to -17 Vdc.
• Recommended Gap Setting: Set the operational gap at 1.27 mm (50 mils) for optimal performance.
• Incremental Scale Factor (ISF): Delivers 7.87 V/mm (200 mV/mil) ±5% including interchangeability error.
• Frequency Response: Supports 0 to 10 kHz with +0, -3 dB limit using up to 305 m of wiring.
• Output Resistance: The proximitor sensor provides a standard 50 Ω output resistance.
• Power Requirements: Needs -17.5 Vdc to -26 Vdc without barriers. With barriers, use -23 Vdc to -26 Vdc.
• Supply Sensitivity: Output voltage changes less than 2 mV per each volt of input change.
• Deviation from Best Fit Straight Line (DSL): Standard 1 metre system achieves less than ±0.025mm (±1 mil) at 0°C to +45°C.

Environmental and Material Durability

• Probe Temperature Range (if equipped): Operates from -51°C to +177°C (-60°F to +350°F). Avoid use below -34°C to protect the pressure seal.
• Housing Rating: Holds an IP66 rating verified by BASEEFA report T07/0709.
• Probe Tip Material: Uses Polyphenylene Sulfide (PPS) for high chemical resistance.
• Probe Case Material: Manufactured from AISI 304 stainless steel for corrosion resistance.
• Housing Material: Features UV-resistant, glass-reinforced PPS thermoplastic with conductive fibers.
• Vibration Isolation Material: Includes extra soft cellular silicone to dampen mechanical shocks.

Mechanical Strength and Installation

• Probe Tensile Strength: Withstands 330 N (75 lb) maximum between the cable and case.
• Housing Strength: Supports 912 N (205 lbf) at 38 mm from the unsupported end.
• Impact Strength: Endures two separate 4 Joule impacts at -39°C and 115°C (BASEEFA certified).
• Recommended Torque for Retaining Nut: Tighten to 29.5 N·m (260 in·lb).
• Recommended Torque for Probe Sleeve Locknut: Tighten to 39.3 N·m (350 in·lb).
• Minimum Target Size: Use a flat target with at least 15.2 mm (0.6 in) diameter.
• Minimum Shaft Diameter: Requires a shaft diameter of 50.8 mm (2.0 in) or larger.

Frequently Asked Questions (FAQ)

• Is this unit brand new and original? Yes, we supply only a brand new and original 330881-00-04-150-06-02 from Bently Nevada.
• Do you have this model in stock? Yes, we keep the PROXPAC XL series model in stock for immediate orders.
• What is your typical shipping time? We ship all orders within 5 days after payment confirmation.
• Which carriers do you use for delivery? We commonly use FedEx, UPS, and DHL for fast global shipping.
• What is your return policy? We support returns within 30 days from the delivery date.
• Why does this model say “No probe”? The option code “00” means this configuration includes only the Proximitor sensor. You need to order a separate 3300 XL 8 mm probe.
• What happens if I operate below -34°C? Exposing any probe to temperatures below -34°C may cause premature pressure seal failure.
• Can I extend the field wiring beyond 305 meters? Longer wiring reduces high-frequency response. See the frequency response graph for signal rolloff details.
