Bently Nevada 330850-50-CN 25mm Panel Mount Sensor

Ordering Option Breakdown

The part number 330850-50-CN represents a specialized Bently Nevada 3300 XL 25 mm Proximitor Sensor configured as follows:

• Base Part Number (330850): 3300 XL 25 mm Proximitor Sensor for non-contact shaft displacement and axial position monitoring.
• Total Length & Mounting Option (-50): 5.0 meters (16.4 feet) total system length with a Panel Mount hardware configuration.
• Agency Approval Option (-CN): Country-specific safety and certification approvals.

Technical Specifications

• System Length: 5.0 meters (16.4 feet)
• Mounting Type: Panel Mount
• Linear Range: 12.7 mm (500 mils)
• Nominal Scale Factor: -0.92 V/mm (-23.3 mV/mil)
• Input Power Supply: -17.5 Vdc to -26 Vdc
• Signal Output Voltage Range: 0 to -20 Vdc

Key Features & Applications

Engineered for high-reliability vibration and thrust positioning systems, this sensor excels in heavy industrial turbomachinery monitoring:

• Compact 5.0m Tuning: Calibrated specifically for 5.0-meter system loop lengths, reducing overall cable clutter in compact enclosures.
• Thermal Stability: Delivers linear signal output across broad temperature variations.
• Interchangeable Design: Compatible with standard 3300 XL 25 mm probe tips and extension cabling without manual recalibration.

Installation Guide

1. Panel Fastening: Mount the sensor securely on a grounded metallic plate using proper mounting screws.
2. Cable Routing: Avoid sharp bends in the extension cable, maintaining a minimum bend radius of 25.4 mm (1.0 inch).
3. Connector Protection: Apply protective connector covers or silicone self-amalgamating tape if installed in high-humidity areas.
4. Zero Point Calibration: Set the probe target distance to achieve the designated DC bias voltage prior to system operation.

Selection Tips

• System Length Verification: Confirm that the installed probe length and extension cable total exactly 5.0 meters to match the -50 Proximitor tuning.
• Environmental Considerations: Verify local plant certification requirements to match the country-specific (-CN) compliance option.

Frequently Asked Questions (FAQ)

Q: Can I use a 9.0-meter cable with this -50 option sensor?
A: No, using a 9.0-meter cable with a 5.0-meter tuned sensor will alter the linear scale factor and introduce measurement error.

Q: What target materials are compatible with this sensor?
A: Standard factory calibration is performed using AISI 4140 steel targets. Contact engineering for alternate target material calibration requirements.
