Product Overview

The 3300/35-12-02-02-00-00 is a high-density thermal surveillance module designed to interface with Resistance Temperature Detectors (RTDs) and Thermocouples. As part of the Bently Nevada 3300 series, this six-channel monitor provides continuous, real-time tracking of critical machinery temperatures. It is engineered to identify overheating conditions in bearings, stator windings, and lubricant systems before thermal expansion or material fatigue leads to equipment failure. This specific configuration supports a variety of sensor inputs and features integrated alarm logic to ensure automated protective actions in high-stakes industrial environments.

Technical Infrastructure and Hardware Specs

Industrial Protection Scenarios

This multi-channel monitoring unit is indispensable for assets where thermal stability is a primary indicator of mechanical health. It is frequently deployed in the following sectors:

• Power Generation: Monitoring stator winding temperatures in large generators to prevent insulation breakdown.

• Hydrocarbon Processing: Tracking pump and compressor bearing temperatures to detect lubrication failure or misalignment.

• Marine Propulsion: Oversight of engine cooling systems and exhaust gas temperatures.

• Heavy Manufacturing: Protecting large-scale electric motors and gearboxes from thermal overload during continuous duty cycles.

• Renewable Energy: Thermal management of gearbox and main bearing assemblies in wind turbine nacelles.

FAQ

Q: Can this 3300/35 module be used with both RTDs and Thermocouples?

A: Yes, the 3300/35 is versatile. While this specific configuration is often set for Platinum RTDs, the module can be ordered or jumper-configured to support various Thermocouple types depending on the internal card setup.

Q: What is the advantage of a six-channel monitor over dual-channel alternatives?

A: The six-channel density allows for a more comprehensive thermal map of a single machine (such as tracking all main bearings and the oil sump simultaneously) while occupying only one slot in the 3300 rack.

Q: Are the internal safety barriers sufficient for hazardous area installations?

A: The inclusion of Option 02 (Internal Barriers) provides an integrated solution for connecting to sensors located in restricted zones, simplifying wiring and reducing the need for external barrier hardware.

Q: How does the monitor indicate a sensor failure?

A: The unit features built-in "Not OK" circuitry that monitors the integrity of the transducer loop. If a wire breaks or a sensor shorts, the monitor triggers a diagnostic alert to prevent false trips.
