Product Overview: Bently Nevada 330190-085-01-CN

The 330190-085-01-CN connects 3300 XL Proximitor Sensors to monitoring systems. This extended temperature range cable withstands harsh industrial conditions with ease. Its armored construction provides excellent mechanical protection against crushing and abrasion. PFA insulation allows continuous operation at temperatures up to 260°C without degradation. Therefore, this cable is ideal for turbine, compressor, and high-heat machinery monitoring in China.

Model Number Breakdown

The 330190-085-01-CN part number reveals several key product features. Base number 330190 identifies this as a 3300 XL extension cable family member. Option 085 specifies an 8.5 meter (27.9 feet) cable length for extended reach. Option 01 indicates armored cable construction for superior mechanical durability. Finally, option CN adds China country approval for local regulatory acceptance.

Part Number Decoding for the 330190-085-01-CN:

• 330190: 3300 XL Extension Cable family

• 085: 8.5 meters (27.9 feet) length

• 01: Armored cable construction

• CN: China country approval

This configuration makes the 330190-085-01-CN suitable for demanding installations in China. The armored jacket protects against physical damage in industrial environments. China approval ensures compliance with local import and safety regulations. Likewise, the extended temperature rating ensures reliable operation near hot machinery.

Electrical Specifications

The 330190-085-01-CN has specific DC resistance characteristics worth noting. Center conductor to center conductor resistance measures 1.87 ± 0.28 ohms. Outer conductor to outer conductor resistance reaches 0.56 ± 0.11 ohms. Typical cable capacitance is 69.9 pF per meter (21.3 pF per foot) across the length.

• RCORE (Center-Center): 1.87 ± 0.28 Ω at 8.5m length

• RJACKET (Outer-Outer): 0.56 ± 0.11 Ω at 8.5m length

• Capacitance: 69.9 pF/m (21.3 pF/ft) typical

• Impedance: 75Ω triaxial construction

• Insulation: PFA (perfluoroalkoxy) for high temperature

The 330190-085-01-CN maintains excellent signal integrity over its full length. Low capacitance ensures minimal signal degradation during long-distance transmission. Consistent impedance prevents troublesome reflections in the measurement system. As a result, the complete probe system maintains specified linearity and accuracy.

Temperature Range and Materials

The 330190-085-01-CN uses extended temperature range materials throughout its construction. PFA insulation replaces standard FEP for superior thermal stability. Operating and storage temperature spans from -52°C to +260°C without performance loss. This exceeds standard cable ratings by over 80 degrees Celsius.

Temperature Specifications for the 330190-085-01-CN:

• Minimum Temperature: -52°C (-62°F)

• Maximum Temperature: +260°C (+500°F)

• Insulation Type: PFA (perfluoroalkoxy)

• Standard Cable Rating: -52°C to +177°C (FEP)

• Application: Turbines, compressors, high-heat areas

The 330190-085-01-CN armored jacket adds significant mechanical protection. Standard extension cable weighs only 34 g/m (0.4 oz/ft) for comparison. Armored version weighs 103 g/m (1.5 oz/ft) for greater durability. Minimum cable bend radius is 25.4 mm (1.0 inch) to prevent internal damage. Always observe this limit during installation to maintain cable integrity.

Connector Specifications

The 330190-085-01-CN uses gold-plated connectors for reliable electrical contact. Connector material consists of gold-plated brass or beryllium copper. Maximum connector torque is 0.565 N•m (5 in•lbf) to prevent overtightening. Exceeding this torque may damage either the connector or cable assembly.

• Connector Material: Gold-plated brass or beryllium copper

• Maximum Torque: 0.565 N•m (5 in•lbf)

• Contact Type: Triaxial for signal and shield integrity

• Compatibility: 3300 XL 8mm components

• Interchangeability: Electrically and physically compatible with non-XL

The 330190-085-01-CN connectors work with standard 3300 components seamlessly. They also function with non-XL 3300 5mm and 8mm components without issue. However, always observe the minimum permissible cable bend radius for all components. This practice ensures reliable electrical contact and long-term mechanical integrity.

Field Wiring Guidelines

The 330190-085-01-CN connects between the Proximitor Sensor and monitoring system. For field wiring beyond the extension cable, use 0.2 to 1.5 mm² (16 to 24 AWG) wire. Bently Nevada recommends using 3-conductor shielded triad cable for optimal results. Tinned field wiring provides better corrosion resistance in harsh environments.

• Wire Gauge: 0.2 to 1.5 mm² (16 to 24 AWG)

• Cable Type: 3-conductor shielded triad recommended

• Maximum Field Wiring Length: 305 meters (1000 feet)

• Termination: Tinned copper preferred

• Signal Rolloff: See frequency response graphs for long runs

Maximum field wiring length between Proximitor Sensor and monitor is 305 meters. Longer field wiring causes signal rolloff at higher frequencies inevitably. Consult Figures 10 and 12 in the product manual for specific derating values. Notably, the 330190-085-01-CN itself does not include this field wiring.

Linear Range and Gap Setting

The 330190-085-01-CN works within the 3300 XL 8mm system linear range. Linear range begins at approximately 0.25 mm (10 mils) from the target. Full linear range spans from 0.25 to 2.3 mm (10 to 90 mils). This corresponds to approximately -1 to -17 Vdc output from the Proximitor.

• Linear Range Start: 0.25 mm (10 mils) from target

• Linear Range End: 2.3 mm (90 mils) from target

• Voltage Range: -1 to -17 Vdc

• Recommended Radial Vibration Gap: -9 Vdc

• Gap Distance at -9 Vdc: Approximately 1.27 mm (50 mils)

For radial vibration measurements, the recommended gap setting is -9 Vdc. This setting centers the probe in the linear range for optimal performance. The 330190-085-01-CN does not affect the linear range characteristics directly. However, cable length and type must match the Proximitor Sensor calibration for accuracy.

China Country Approval

The 330190-085-01-CN carries specific China country approval for local use. This certification (option CN) ensures compliance with Chinese import regulations.

Mechanical Specifications

The 330190-085-01-CN armored cable weighs significantly more than standard versions. Total cable weight is approximately 0.88 kg for the 8.5 meter length alone. The cable remains flexible despite the protective armor layer. Minimum bend radius of 25.4 mm allows routing in tight spaces.

• Armored Weight: 103 g/m (1.5 oz/ft)

• Total Cable Weight: Approximately 0.88 kg (cable only)

• Connector Material: Gold-plated brass

• Minimum Bend Radius: 25.4 mm (1.0 inch)

• Armor Type: Helically wound steel or bronze

Handle the 330190-085-01-CN with care to avoid kinking the cable. Exceeding the minimum bend radius may damage internal conductors permanently. The armor provides excellent protection but is not rigid conduit. Therefore, support the cable properly along its full length during installation.

Installation Guidelines

Install the 330190-085-01-CN between the Proximitor Sensor and the probe. Connect the cable to the Proximitor Sensor as the first step. Then route the cable to the junction box or monitor location carefully. Finally, secure the cable using non-metallic ties at regular intervals.

Key Installation Points for the 330190-085-01-CN:

• Bend Radius: Maintain minimum 25.4 mm (1.0 inch)

• Connector Torque: Tighten to 0.565 N•m (5 in•lbf) maximum

• Cable Support: Use plastic ties, not metal

• Separation: Keep 30 cm from high-voltage cables

• Grounding: Connect shield at one end only

Never pull the 330190-085-01-CN by the connectors during installation. Pull only on the cable jacket when routing through conduits. Inspect all connectors for damage before mating them together. Apply dielectric grease to connectors in wet environments for protection. Finally, test continuity after installation to verify proper connection throughout.
