Bently Nevada 330130-040-01-00 Armored Extension Cable
Product Introduction
The Bently Nevada 330130-040-01-00 is a precision-engineered extension cable designed for the 3300 XL series proximity monitoring systems. This 4.0-meter (11.5 feet) cable establishes a reliable connection between the 3300 XL 8 mm proximity probe and the Proximitor sensor. Manufactured in the U.S.A., this model features an armored jacket that safeguards the cable from physical damage in harsh industrial environments. Additionally, the 330130-040-01-00 incorporates gold-plated ClickLoc connectors for corrosion resistance and a secure electrical interface. It serves as a critical component in vibration and position monitoring applications for turbines, compressors, and other rotating machinery.
Key Technical Specifications
This section details the essential electrical parameters of the 330130-040-01-00.
Cable Length: The 330130-040-01-00 provides a length of 4.0 meters (11.5 feet). This shorter length is ideal for installations where the probe and Proximitor sensor are located in close proximity.
Cable Type: This model includes the standard armored cable option, identified by the "01" in the product number. The armor provides robust protection against crushing, abrasion, and impact.
Connectors: The cable uses corrosion-resistant, gold-plated ClickLoc connectors. These connectors ensure a positive and reliable electrical connection between the probe, the 330130-040-01-00 cable, and the Proximitor sensor.
Capacitance: The typical extension cable capacitance is 69.9 pF/m (21.3 pF/ft). This low and stable capacitance is essential for maintaining the accuracy and linearity of the proximity measurement system.
DC Resistance (Center Conductor): For the 4.0-meter length, the center conductor resistance (RCORE) is 0.88 ± 0.13 Ω.
DC Resistance (Outer Conductor): For the 4.0-meter length, the outer conductor resistance (RJACKET) is 0.26 ± 0.05 Ω.
Compatibility and System Integration
The Bently Nevada 330130-040-01-00 is engineered to work seamlessly with specific 3300 XL system components. It accepts input from one non-contacting 3300-series 5 mm, 3300 8 mm, or 3300 XL 8 mm proximity probe. Furthermore, for optimal performance, we recommend pairing it with a 3300 XL 8 mm Proximitor sensor.
Power Requirements: The Proximitor sensor requires a DC power supply between -17.5 Vdc and -26 Vdc when installed without barriers, with a maximum current consumption of 12 mA. When using safety barriers, the voltage range shifts to -23 Vdc to -26 Vdc. Note that operating at a voltage more positive than -23.5 Vdc can reduce the linear range.
Supply Sensitivity: The system demonstrates less than a 2 mV change in output voltage per volt change in input voltage. This low sensitivity ensures stable readings despite minor power fluctuations.
Output Resistance: The output resistance is 50 Ω, ensuring compatibility with standard monitoring equipment.
Field Wiring: For wiring between the Proximitor sensor and the monitor, we recommend using a 3-conductor shielded triad cable with tinned wiring. The maximum field wiring length is 305 meters (1,000 feet), though you should check frequency response graphs for potential signal rolloff at high frequencies.
Mechanical and Environmental Features
The 330130-040-01-00 is built to withstand demanding conditions commonly found in power generation and heavy industry.
Armored Construction: The armored jacket provides excellent protection against mechanical stresses. This includes protection from crushing, impact, and abrasion during installation and operation.
Patented CableLoc Design: The cable incorporates a patented CableLoc design. This provides 330 N (75 lbf) pull strength, securely attaching the probe cable to the probe tip and preventing accidental disconnection.
TipLoc Molding: A patented TipLoc molding method provides a more robust bond between the probe tip and the probe body. This improves the overall durability of the probe assembly.
Connector Protection: Each 330130-040-01-00 cable includes silicone tape for optional connector sealing. However, we do not recommend silicone tape for applications where the probe-to-cable connection will be exposed to turbine oil.
Probe Sealing: The 3300 XL 8 mm probes feature a Viton® O-ring seal. This seals differential pressure between the probe tip and the case. For applications requiring pressure testing, please contact the custom design department.
Humidity Resistance: The system shows less than a 3% change in the Average Scale Factor (ASF) when tested in 93% humidity per IEC 68-2-3 for up to 56 days. This confirms reliable operation in humid environments.
Installation Guidelines
Proper installation of the Bently Nevada 330130-040-01-00 ensures accurate and reliable system performance.
Connect the Probe: Securely attach the proximity probe connector to one end of the 330130-040-01-00 cable. The ClickLoc design provides a positive locking mechanism.
Connect to Proximitor: Attach the other end of the cable to the Proximitor sensor connector.
Cable Routing: Route the cable carefully to avoid sharp bends, excessive tension, or contact with high-temperature surfaces. The armored jacket offers protection, but careful routing is still best practice.
Gapping: For standard calibration, gap the 8 mm probe at 1.27 mm (50 mils) from an AISI 4140 steel target. The linear range begins at approximately 0.25 mm (10 mils) and extends to 2.3 mm (90 mils), with a corresponding output range of approximately -1 to -17 Vdc.
Environmental Conditions: The specified performance data is valid for ambient temperatures between +18˚C and +27˚C (+64˚F to +80˚F) at a maximum altitude of 2000 meters.
