Product Overview

The Bently Nevada 3300/20-12-01-02-01-02 is a high-precision dual-channel thrust position monitor designed for the continuous protection of rotating machinery. By measuring the axial movement of a shaft relative to the thrust bearing clearance, this module provides critical early warning of potential bearing failure or catastrophic machine contact. This specific configuration is manufactured in the United States and is optimized for systems requiring internal safety barriers and hermetically-sealed alarm relays. It interface seamlessly with standard proximity transducer systems to deliver real-time displacement data to operators and automated shutdown systems.

Specialized Hardware Specifications

Strategic Industrial Deployment

This monitoring module is essential for heavy-duty industrial assets where axial stability is a critical safety parameter. Its primary role is to prevent mechanical over-travel in high-speed rotating equipment. Common deployment environments include:

• Centrifugal and axial compressor protection in petrochemical facilities.

• Steam turbine thrust bearing monitoring in power generation plants.

• Large industrial pump vibration and displacement oversight.

• Mainline gas transmission turbines requiring CSA-certified safety components.

• Gearbox axial movement tracking in heavy manufacturing.

FAQ

Q: Does this specific 3300/20 model support metric measurement ranges?

A: Yes, this configuration (Option 12) is specifically calibrated for a metric full-scale range of 1.0-0-1.0 mm, providing precise axial displacement monitoring in millimeters.

Q: What is the benefit of the hermetically-sealed relay option?

A: Hermetically-sealed relays provide a higher level of reliability in harsh or volatile environments by preventing moisture, dust, and corrosive gases from affecting the electrical contacts.

Q: Can this monitor be used in hazardous locations requiring safety barriers?

A: Yes, this unit includes the 02 safety barrier option, which features internal barriers, making it suitable for specific regulated environments alongside its CSA/NRTL/C approval.

Q: Is a Certificate of Origin available for international shipping requirements?

A: A Certificate of Origin (COO) can be provided upon request for this American-made component to satisfy customs and trade compliance documentation.

Q: What transducer systems are compatible with the 01 input option?

A: The 01 input option is engineered to work with 3300 or 7200 Proximitor systems that provide a scale factor of 200 mV/mil.
