Bently 330192-00-12-90-CN

3. Technical Specifications

Cable Construction

• Conductor Material: Tinned copper, ensuring excellent electrical conductivity and resistance to corrosion, which extends the cable’s service life in humid or industrial environments.
• Insulation Material: Cross-linked polyethylene (XLPE), providing high thermal stability, resistance to abrasion, and protection against electrical breakdown.
• Shielding: Double-shielded design (foil shield + braided shield), with a shielding effectiveness of ≥90 dB at 100 MHz. This minimizes electromagnetic interference (EMI) and radio frequency interference (RFI) from nearby electrical equipment, ensuring accurate signal transmission.
• Outer Jacket: Polyvinyl chloride (PVC) or polyurethane (PU) (depending on specific configurations), offering resistance to oil, chemicals, and mechanical impact; the jacket is also flame-retardant to meet industrial safety standards.

Electrical Specifications

• Impedance: 50 ohms (characteristic impedance), matched to the impedance of 3300 Series proximity probes and signal conditioners to avoid signal reflection and loss.
• Capacitance: ≤100 pF per meter at 1 kHz, ensuring low signal delay and maintaining signal integrity over the cable length.
• Resistance: ≤5 ohms per 100 meters (conductor resistance), minimizing voltage drop and ensuring consistent power supply to the proximity probe.
• Operating Voltage: Rated for 300 V AC/DC (maximum), compatible with the power requirements of Bently 3300 Series measurement systems.

Physical & Environmental Specifications

• Cable Length: 12 meters (as indicated by the “12” in the part number; Bently offers other lengths for different installation needs, but 330192-00-12-90-CN is fixed at 12m).
• Connector Type: One end features a Bently-specific bayonet connector (compatible with 3300 Series proximity probes), and the other end has a terminal block or matching connector for easy integration with signal conditioners (the “90” in the part number typically refers to a 90-degree connector orientation, optimizing space in tight installation areas).
• Operating Temperature Range: -40°C to +85°C, allowing reliable operation in both cold industrial facilities (e.g., refrigeration plants) and high-temperature environments (e.g., power plant turbine halls).
• Vibration Resistance: Compliant with IEC 60068-2-6 standards (20 g acceleration, 10-2000 Hz), ensuring the cable remains stable and functional under the vibration generated by rotating machinery.
• Ingress Protection (IP) Rating: IP65 for the connector area, protecting against dust ingress and low-pressure water jets, suitable for use in dusty or damp industrial settings.

4. Functional Features

• High Signal Integrity: The double-shielded design and impedance-matched construction eliminate signal distortion and interference, ensuring that the proximity probe’s measurements (e.g., shaft displacement, vibration amplitude) are transmitted accurately to the signal conditioner. This accuracy is critical for early detection of machinery anomalies (such as misalignment or bearing wear).
• Wide Environmental Adaptability: With its robust insulation, flame-retardant jacket, and broad temperature range, the cable performs reliably in harsh industrial conditions—including exposure to oil, chemicals, dust, and extreme temperatures—without degradation in performance.
• Easy Installation & Compatibility: The pre-terminated connectors (with a 90-degree orientation for space efficiency) and fixed length (12m) simplify on-site installation, reducing setup time. It is fully compatible with all Bently 3300 Series proximity probes and signal conditioners, eliminating the need for additional adapters or modifications.
• Long-Term Durability: The tinned copper conductors, XLPE insulation, and chemical-resistant outer jacket resist corrosion, abrasion, and aging, ensuring a service life of up to 10 years in typical industrial operations. This reduces maintenance costs and the need for frequent cable replacements.
• Safety Compliance: The cable meets global industrial safety standards, including UL 1015 (for electrical safety in the US), CSA C22.2 No. 210 (for Canada), and IEC 60227 (for international use), ensuring compliance with safety regulations in various regions.

5. Application Scenarios

• Power Generation Industry: Used in coal-fired power plants, natural gas power plants, and nuclear power plants to connect proximity probes to signal conditioners on steam turbines, gas turbines, and generators. It monitors shaft vibration, axial displacement, and rotational speed, helping prevent catastrophic failures that could lead to power outages.
• Oil & Gas Industry: Deployed in offshore drilling platforms, refineries, and pipeline compressor stations. It is used with proximity probes on centrifugal compressors, reciprocating pumps, and gearboxes to monitor machinery health in explosive or corrosive environments (the cable’s chemical resistance and flame-retardant design make it suitable for hazardous areas classified as Zone 2).
• Petrochemical Industry: Integrated into ethylene crackers, polymer reactors, and process pumps. The cable’s ability to withstand high temperatures and oil exposure ensures reliable monitoring of rotating equipment, supporting continuous production and preventing costly process shutdowns.
• Metallurgical Industry: Used in steel mills and aluminum smelters to monitor the condition of rolling mill drives, fan motors, and hydraulic pumps. The cable’s vibration resistance and dust protection make it ideal for the dusty, high-vibration environment of metallurgical facilities.
• Marine & Shipping Industry: Installed on marine diesel engines, propeller shafts, and auxiliary pumps aboard ships and offshore vessels. Its wide temperature range (-40°C to +85°C) and moisture resistance (IP65 rating) allow it to operate reliably in marine environments, where temperature and humidity fluctuate significantly.
• Heavy Machinery & Manufacturing: Applied in cement plants, mining equipment (e.g., crushers, conveyors), and automotive manufacturing lines. It monitors the vibration and position of motors, gearboxes, and robotic arms, ensuring equipment reliability and reducing unplanned downtime in high-volume production settings.
