Bently Nevada 330450-80 Accelerometer: Industrial Vibration Sensor

System Overview: Bently Nevada 330450-80

The Bently Nevada 330450-80 is a high-performance, acceleration-sensing device designed specifically for monitoring vibration in extreme environments. Featuring an integrated hardline cable and a hermetically sealed 300 series stainless steel housing, this Accelerometer is built for long-term reliability on high-temperature rotating assets.

Configuration & Ordering Breakdown

The 330450-80 model is categorized by its specialized integration capabilities:

• 330450: High-Temperature Acceleration Sensor
  • Length (-80): 8-meter integral hardline cable.

Key Technical Specifications

• Sensitivity: 100 mV/g (10.2 mV/m/s²) ±5%.
• Frequency Range: 15 Hz to 10,000 Hz.
• Temperature Tolerance: Sensor/Cable up to 400°C; Electronics up to 100°C.
• Survivability: 2,500 g peak shock resistance.
• Input Voltage: -24 ± 0.5 Vdc (2 mA nominal bias).
• Signal Integrity: Up to 305 meters (1000 ft) cable extension without loss.

Diagnostic & Operational Capability

The 330450-80 is designed for ease of field verification. The 3-pin Mil-C-5015 receptacle provides a secure, vibration-resistant connection, while the hermetic seal prevents ingress in harsh, humid industrial environments. Its polarity design ensures unambiguous signal output, reducing commissioning errors during large-scale sensor deployments.

Global PLC Spare HUB's Insight

We identify the 330450-80 as the gold standard for turbine and gas compressor vibration monitoring. The integrated hardline construction is critical; it eliminates typical junction box failure points found in lower-tier sensors. For engineers, this is the most reliable choice when dealing with surface temperatures that would otherwise melt standard cable insulation.

Logistics & Quality Guarantee

• Shipping: Expedited worldwide shipping via FedEx, UPS, and DHL.
• Lead Time: Rapid dispatch within 24–48 hours.
• Guarantee: Each sensor includes a 12-month industrial quality guarantee.

Professional Frequently Asked Questions

What are the specific requirements for installing this in a hazardous (Zone 0/1) area?
The device must be connected to an intrinsically safe associated apparatus in compliance with EN 60079-25 standards. Always refer to installation drawing 168078.

Can I use this sensor in a high-humidity environment?
Yes, the sensor is hermetically sealed and rated for up to 100% relative humidity, making it suitable for wet or outdoor industrial applications.

What should I consider regarding the hardline cable bend radius?
Maintain a minimum bend radius of 51mm (2.0in) to prevent structural damage or impedance changes in the internal conductors.

Selection Guide: Why is the 8-meter (-80) cable length preferred?
The integral cable minimizes signal degradation. The 8-meter length allows the electronic housing to be mounted far enough from the high-temperature machine surface to remain within the 100°C limit.

Experience Tip: How do I test the sensor without a shaker table?
Perform a bias voltage check; the output should read -12 Vdc ±0.5 Vdc. If the bias is outside this range, check the power supply and cabling for open or short circuits.
