Product Overview

The 3300/36-13-12-03-01-00 is a high-reliability dual-channel thermal monitoring module designed to integrate seamlessly into the Bently Nevada 3300 series rack. This instrument provides continuous, real-time surveillance of temperature variables across critical rotating machinery components. By processing signals from Resistance Temperature Detectors (RTDs) or Thermocouples, the module identifies thermal trends that may indicate bearing wear, lubricant degradation, or winding insulation breakdown. Its dual-channel architecture ensures dedicated oversight for two separate points, offering both local display and automated alarm outputs to prevent costly equipment downtime.

Primary Engineering Deployments

The application of this temperature monitor is essential for high-value industrial assets where thermal stability is a key performance indicator. Typical installation environments include:

• Bearing Temperature Tracking: Monitoring radial and thrust bearing temperatures in large-scale turbines and generators.

• Motor Protection: Identifying heat buildup in stator windings for medium to high-voltage electric motors.

• Compressor Safety: Tracking discharge gas temperatures in multi-stage centrifugal compressors.

• Lube Oil Systems: Continuous temperature oversight of oil reservoirs and heat exchangers to ensure proper viscosity.

• Pumping Stations: Protecting industrial pump seals and housings from friction-induced overheating.

FAQ

Q: Does the 3300/36 module provide separate alarm setpoints for each channel?

A: Yes, each of the two channels features independently adjustable Alert and Danger setpoints, allowing for customized protection profiles based on the specific requirements of the monitored point.

Q: Can this specific model configuration be used in corrosive atmospheres?

A: This unit is equipped with hermetically-sealed relays, which provide superior protection against oxidation and corrosive contaminants compared to standard epoxy-sealed versions.

Q: How does the monitor respond if a transducer wire is disconnected?

A: The system incorporates "Not OK" status logic. If the transducer loop is interrupted or fails, the module activates a fault indicator to prevent false alarms while notifying maintenance personnel of the signal loss.

Q: Is the digital display visible in low-light industrial environments?

A: The 3300/36 faceplate is designed for high visibility and includes status LEDs (OK, Alert, Danger) that provide immediate visual confirmation of the machine's thermal health even from a distance.

Q: What is the primary difference between the 3300/35 and 3300/36 models?

A: While the 3300/35 is a high-density six-channel monitor, the 3300/36 is a dual-channel version that offers more granular local display and control for two specific, high-criticality measurement points.
