General

  • Manufacturer GE / Bently Nevada
  • Model 3300/30
  • Condition New Original ready stock
  • Product Family 3300/30-08-04-02-01,3300/30-07-03-01-00,3300/30-10-02-01-00
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.
  • Sensor Support: Supports multiple industry standard thermocouples, including Type J, K, E, and T. Each module is factory-selected based on the chosen type, but can be converted via internal hardware changes.
  • Rack Compatibility: Fully compatible with the 3300 monitoring system rack. It can be installed in the same rack as other 3300 series monitors such as vibration, displacement, and differential expansion monitors, sharing power and system monitoring modules.
  • Backward Compatibility: Although the 3300 system has been gradually replaced by the 3500 system, the 3300/30 can still be used as a spare for older systems or interoperate with modern System 1 software via a communication interface.
  • Hardware Jumper Configuration: Most settings are configured via internal jumpers on the side of the module, including: Alarm Logic: Locking or Non-latching. Alarm Delay: Sets the delay time before alarm triggering. Cold Junction Compensation: Includes cold junction compensation logic configuration essential for thermocouple measurements.
  • Polypotentiometer Calibration: The module's front panel features potentiometers for zero and span fine-tuning, enabling on-site calibration with a high-precision millivolt signal generator.
  • Span Definition: Jumpers allow selection of Celsius (°C) or Fahrenheit (°F) display and their corresponding measurement ranges.
  • Thermocouple Connection: Supports standard thermocouple leads connected to the terminal block at the rear of the rack. The module incorporates cold junction compensation circuitry to ensure accurate measurements despite temperature variations at the connection points.
  • Logger Output: Each channel provides an independent analog output signal (typically 4-20 mA or 1-5 Vdc) for real-time temperature data transmission to a DCS, PLC, or historical data logger.
  • Serial Data Interface (SDI): Digital readings and alarm status of the modules can be uploaded to a host computer monitoring system via the rack-mounted 3300/03 system monitor through RS-232 or RS-422 interfaces.
  • Buffered Signal Interface: The front panel provides buffered voltage output for each channel, allowing technicians to directly read the raw millivolt signals of the thermocouples using a multimeter or diagnostic equipment without shutting down the system.
Description
The Bently Nevada 3300/30 Six-Channel Temperature Monitor is specifically designed to address the need for reliable, continuous temperature monitoring in critical rotating machinery and industrial process environments. By accepting up to six thermocouple inputs, the Bently Nevada 3300/30 enables operators to monitor multiple temperature points simultaneously, helping detect abnormal temperature conditions early and prevent equipment damage. It is widely used in industries such as power generation, oil and gas, petrochemical processing, and heavy manufacturing where precise thermal monitoring is essential for operational safety.

The Bently Nevada 3300/30 Six-Channel Temperature Monitor supports both grounded and non-grounded tip thermocouples and allows user programming for several common thermocouple types. Supported sensor options include Type J and Type K thermocouples with measurement ranges up to 500°C (1000°F) as well as Type T and Type E thermocouples with ranges up to 250°C (500°F). This flexibility allows the Bently Nevada 3300/30 to adapt to a wide range of temperature measurement requirements across turbines, compressors, motors, and other critical machinery.

For accurate temperature monitoring, the Bently Nevada 3300/30 Six-Channel Temperature Monitor delivers excellent measurement performance with a display accuracy within ±1°C (±1.8°F) when the tenths digit is displayed and ±1.5°C (±2.7°F) when the tenths digit is not shown. These accuracy specifications are defined at an ambient temperature of +25°C (+77°F), ensuring dependable readings for operators and maintenance teams responsible for machine health monitoring.

Designed for continuous operation in industrial environments, the Bently Nevada 3300/30 operates within a temperature range of 0°C to +65°C (+32°F to +150°F) and can be safely stored in conditions from −40°C to +85°C (−40°F to +185°F). It also supports relative humidity levels up to 95% (non-condensing), allowing installation in demanding plant environments. With a nominal power consumption of only 4 watts, the Bently Nevada 3300/30 Six-Channel Temperature Monitor provides efficient monitoring performance while maintaining system reliability.

Within the 3300 monitoring system family, the Bently Nevada 3300/30 is designed for thermocouple-based temperature measurement, while the related 3300/35 RTD Monitor supports resistance temperature detectors. Compared with many single-channel temperature monitoring devices, the Bently Nevada 3300/30 Six-Channel Temperature Monitor integrates six independent monitoring channels into a single module, simplifying system architecture and improving monitoring efficiency across multiple machine components.
