The Bently Nevada 3300/46 Ramp Differential Expansion Monitor is an advanced instrument for measuring and monitoring differential expansion. It excels in applications where traditional proximity probe-based methods are impractical.

Key Features and Benefits

• Ramp Surface Measurement: The 3300/46 uses ramp surfaces on the rotor to measure differential expansion. This approach extends measurement ranges with smaller transducers.
• Flexible Transducer Placement: Utilizing ramp surfaces offers flexibility in mounting transducers. This flexibility simplifies installation and maintenance.
• Magnitude and Direction Indication: The monitor displays differential expansion’s magnitude and direction on its LCD. This feature provides clear, actionable information.
• Alarm Setpoints: You can configure four alarm setpoints (two over and two under) to alert operators to potential issues.
• Wide Range of Applications: The 3300/46 is ideal for various rotating machinery, including turbines, pumps, compressors, and generators.

Typical Applications

• Monitoring Differential Expansion: The monitor is effective for large rotating machines where traditional methods fall short.
• Detecting Mechanical Issues: It helps identify early signs of misalignment, thermal growth, or other mechanical problems.
• Protecting Equipment: The 3300/46 safeguards critical equipment from damage and reduces downtime.
