Vibration Monitoring Solution – BENTLY NEVADA 330730-040-00-00 | 3300 Series Interconnect Cable
Where This Product Is Used
The BENTLY NEVADA 330730-040-00-00 is a precision interconnect cable engineered for use within the 3300 Series Proximity Transducer System. It serves as the critical signal-carrying link between the proximity probe and the extension cable or monitor in continuous rotating machinery surveillance applications.
Typical deployment environments include:
- Steam and gas turbine bearing vibration monitoring systems
- Centrifugal and axial compressor shaft displacement measurement
- Pump and motor radial/axial position monitoring
- Gearbox and expander machinery protection panels
- Petrochemical plant rotating equipment health monitoring
- Power generation facilities requiring API 670-compliant instrumentation
This cable is specified wherever engineers require a 40-inch (1016 mm) extension within a 3300 Series proximity loop, maintaining signal integrity from probe tip to monitor input.

Why Engineers Specify This Model
- System-Matched Performance: Factory-calibrated to maintain the precise electrical characteristics required by the 3300 Series eddy-current proximity system — no field trimming required.
- 40-Inch Length Flexibility: The 330730-040-00-00 length designation (40 inches) fills the gap between standard probe tip and extension cable in tight machinery installations where longer runs are impractical.
- Signal Integrity: Low-loss coaxial construction minimizes capacitance variation, ensuring accurate gap voltage output across the full measurement range.
- Harsh Environment Rated: Armored jacket and PTFE insulation resist oil, steam, vibration fatigue, and high-temperature exposure common in turbomachinery enclosures.
- Drop-In Replacement: OEM-equivalent construction allows direct substitution in existing 3300 Series loops without recalibration of the monitor.
- Reduced Downtime Risk: Stocking this cable as a critical spare eliminates extended outages caused by proximity system cable failures during planned or unplanned maintenance windows.

Application-Specific FAQ
Q: Can the 330730-040-00-00 be used with non-Bently Nevada monitors?
A: This cable is calibrated for the Bently Nevada 3300 Series eddy-current system. Using it with third-party monitors may result in incorrect gap voltage output and measurement errors. Consult your monitor manufacturer’s compatibility documentation before substitution.
Q: What is the difference between the interconnect cable and the extension cable?
A: The interconnect cable (330730 series) connects directly to the probe body and is typically short (5–40 inches). The extension cable (330130 series) runs the longer distance from the interconnect to the monitor, often 5–30 meters. Both must be matched to the same probe series for accurate calibration.
Q: Is the 40-inch length field-cuttable?
A: No. The 330730-040-00-00 is factory-terminated and calibrated at 40 inches. Cutting or splicing the cable will alter its electrical characteristics and invalidate system calibration. Select the correct length suffix (e.g., -020 for 20 inches, -050 for 50 inches) for your installation geometry.
Q: Do you stock other lengths in the 330730 series?
A: Yes. Contact us with your required length and we will confirm availability. Common lengths include 5, 10, 20, 25, 40, and 50 inches.
Q: Can this cable be used in a hazardous (classified) area?
A: The standard 330730-040-00-00 is suitable for general industrial environments. For ATEX/IECEx Zone 1 or Zone 2 classified areas, verify the full part number suffix and consult the Bently Nevada hazardous area approval documentation. Konmask can assist with sourcing the appropriate certified variant.
