Description

Designed to withstand extreme thermal environments, the Bently Nevada 330450-20-05 provides precise, high-temperature casing acceleration measurements on rotating machinery. This heavy-duty acceleration sensor system is engineered to capture high-frequency vibration data, enabling early detection of structural degradation, bearing wear, and mechanical imbalances. By operating reliably under severe thermal conditions, the system supports comprehensive predictive maintenance programs across critical industrial assets.

The system consists of a robust accelerometer coupled with a high-integrity signal transmission path. This model features a 2.0-meter integral cable (designated by the -20 option) and a standardized connection/mounting configuration (designated by the -05 option). It interfaces seamlessly with Bently Nevada 3500 Series machinery protection systems and other compatible industrial monitors to deliver real-time diagnostic inputs.

Features

• High-Temperature Resilience: Engineered specifically for machinery locations subjected to extreme operational heat.
• Broad Frequency Range: Captures critical vibration characteristics across a wide span of 15 Hz to 10,000 Hz.
• Precision Sensitivity: Delivers a highly stable 10.2 mV/m/s2 (100 mV/g) output with a tight +/-5% tolerance.
• Linear Performance: Maintains precise linear output within +/-2% up to the peak acceleration limit.
• Robust Cable Integration: Includes a durable 2-meter armored or braided cable for robust routing in harsh industrial bays.

Applications

• Gas turbines and steam turbines
• High-temperature process pumps and compressors
• Exhaust fans and ventilation systems in industrial ovens
• Power generation and petrochemical processing facilities

Installation Guidelines

To ensure optimal signal integrity and longevity of the sensor system, please adhere to the following installation parameters:

• Mounting Surface: Mount the accelerometer only on a clean, flat, and prepared machine surface to ensure accurate high-frequency transmission.
• Torque Specifications: Tighten the mounting stud to the specified OEM torque limits using a calibrated torque wrench. Do not overtighten.
• Cable Routing: Secure the 2-meter cable to rigid structures using approved conduit or tie-downs to prevent cable whip or mechanical damage in high-vibration zones. Ensure minimum bend radius guidelines are respected.
• Grounding: Ensure the sensor case is properly isolated or grounded in accordance with facility instrumentation guidelines to eliminate ground loops.
