General

  • Manufacturer GE / Bently Nevada
  • Model 3300/35
  • Condition New Original ready stock
  • Product Family 3300/35-10-02-01-00,3300/35-09-01-00-00,3300/35-08-04-02-01
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Continuous Protection: This module complies with API 670 standards for bearing temperature monitoring, providing uninterrupted hardware-level alarm monitoring without relying on external controllers.
  • Hazardous Area Certification: Optional CSA/NRTL/C certification (Class I, Division 2, Groups A, B, C, D), suitable for flammable and explosive industrial environments such as oil and petrochemical plants.
  • Self-Diagnostic Functions: Not OK Status Monitoring: When the RTD sensor is open-circuited or short-circuited, the monitor activates the "Not OK" state. Fault Clamping: In case of a fault, the recorder output can be set to a value below 4mA (e.g., 2mA) so that the DCS system can identify sensor failure.
  • Relay Logic: Supports "Oring" alarm logic, meaning that reaching a threshold in any of the six channels will trigger the common relay.
  • Bearing Temperature Monitoring: The most common application is monitoring the temperature of radial and thrust bearings in large motors, pumps, compressors, and turbines.
  • Motor Winding Protection: Monitors the temperature of stator windings in large AC/DC motors to prevent insulation damage due to overload or cooling failure.
  • Lubricating Oil Station Monitoring: Integrated into the Lube Oil Console, monitors supply and return oil temperatures.
  • Supported RTD Types: Supports various standard RTDs, including 100 Ω Platinum, 10 Ω Copper, and 120 Ω Nickel.
  • Sensor Input: Supports 3-wire RTD connections with automatic line resistance compensation to ensure measurement accuracy over long distances.
  • Analog Output: Each channel can be configured with an independent recorder output, selectable from 4 to 20 mA or 0 to -10 Vdc, facilitating connection to external control systems.
  • Digital Integration: The 3300/03 system monitor uses SDI (Serial Data Interface) to upload temperature readings and alarm status from six channels to the System 1 software or a host computer monitoring platform in real time.
  • Physical Connection: Sensor cables are connected via terminal blocks at the rear of the rack; alarm signals are output via a common relay or optional independent relay terminal on the rack backplane.
Description
The Bently Nevada 3300/35 Six-Channel RTD Monitor is specifically engineered to address the challenges of accurate temperature monitoring in industrial environments. It supports six independent channels for resistance temperature detectors (RTDs), allowing precise measurement across multiple points in a system. This capability is critical for ensuring process stability and early detection of potential overheating or thermal anomalies.

Unlike simpler temperature monitors, the 3300/35 RTD Monitor accommodates a wide range of RTD types, including 3-wire and 4-wire configurations: 100 Ω platinum (a=0.00385 or a=0.00392) for up to 500°C/1000°F, 120 Ω nickel for up to 150°C/300°F, and 10 Ω copper for up to 100°C/200°F. This versatility makes it suitable for virtually all industrial temperature measurement needs, from critical rotating machinery to high-precision thermal processes.

The monitor delivers high display accuracy, within ±1°C (1.8°F) when the tenths digit is displayed and ±1.5°C (2.7°F) otherwise, at ambient temperature of +25°C (+77°F). Its nominal power consumption of 4 watts ensures low energy impact, while its operational range of 0°C to +65°C (32°F to 150°F) and storage range of -40°C to +85°C (-40°F to +185°F) make it robust in challenging industrial environments. Relative humidity tolerance up to 95% non-condensing further enhances its reliability.

In comparison to the 3300/30 TC Monitor, which handles thermocouples, the 3300/35 RTD Monitor provides greater stability and precision for applications requiring resistance-based measurements. Its six independent channels offer streamlined monitoring without requiring multiple instruments, reducing installation complexity and maintenance overhead.

Overall, the Bently Nevada 3300/35 Six-Channel RTD Monitor stands out for its broad RTD compatibility, high measurement accuracy, compact power consumption, and robust environmental tolerance, making it an ideal solution for industrial facilities seeking reliable temperature monitoring and protection.
