Technical Specifications of the 330190-075-01-00

Cable Configuration

Turning first to the cable configuration, the Bently Nevada 330190-075-01-00 includes a 7.5 meter (24.6 feet) length. The cable option (01) specifies armored construction for superior mechanical protection. Agency approval option (00) indicates that no specific hazardous area approvals are required for this version. The minimum cable bend radius is 25.4 mm (1.0 inch), which must be observed during installation.

Electrical Specifications

Regarding electrical characteristics, the Bently Nevada 330190-075-01-00 uses 75Ω triaxial construction. For extended temperature range applications, the insulation is perfluoroalkoxy (PFA). Nominal core resistance (RCORE) from center conductor to center conductor measures 1.65 ± 0.25 Ω. Outer conductor resistance (RJACKET) measures 0.49 ± 0.10 Ω. Extension cable capacitance is 69.9 pF/m (21.3 pF/ft) typical.

Temperature Range

The extended temperature range cable operates from -52°C to +260°C (-62°F to +500°F). This represents a significant improvement over standard cable (which only reaches +177°C). Consequently, the Bently Nevada 330190-075-01-00 is ideal for high-temperature machinery applications such as turbines and compressors.

Connector and Torque Specifications

Connector material is gold-plated brass or gold-plated beryllium copper. The maximum connector torque is 0.565 N•m (5 in•lbf). Hand-tightening is recommended; do not exceed this torque value.

Weight

The armored extension cable weighs 103 g/m (1.5 oz/ft). For this 7.5 meter cable, the total weight is approximately 0.77 kg.

Field Wiring and System Integration

Field Wiring Recommendations

For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) conductors. Three-conductor shielded triad cable with tinned field wiring is recommended. Maximum length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). For high-frequency applications, consult the frequency response graphs for signal rolloff when using longer field wiring lengths.

Linear Range and Gap Setting

The linear range is 2 mm (80 mils). Linear range begins at approximately 0.25 mm (10 mils) from the target. The range extends from 0.25 to 2.3 mm (10 to 90 mils), corresponding to approximately -1 to -17 Vdc. The recommended gap setting for radial vibration is -9 Vdc, which translates to approximately 1.27 mm (50 mils).

Compatibility and Compliance

Component Interchangeability

The Bently Nevada 330190-075-01-00 is both electrically and physically interchangeable with non-XL 3300 5 mm and 8 mm components. This interchangeability applies when the minimum permissible cable bend radius (25.4 mm / 1.0 in) is observed.

FCC Compliance

This device complies with part 15 of the FCC Rules. Operation is subject to two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

EMC and RoHS Compliance

For EMC, the device complies with European Community Directive 2014/30/EU. Standards include EN 61000-6-2 (Immunity for Industrial Environments) and EN 61000-6-4 (Emissions for Industrial Environments). For RoHS, it complies with Directive 2011/65/EU.

Maritime Compliance

Maritime compliance includes 2019 Rules for Conditions of Classification, Part 1, 1-1-1/7.7, 1-1-A3, 1-1-A4. Additionally, for offshore units and structures, it complies with 1-1-4/9.7, 1-1-A2, 1-1-A3.

Functional Safety Certification

The Bently Nevada 330190-075-01-00 carries important functional safety ratings. For SIL 2 applications, the Hardware Fault Tolerance (HFT) is 0. For SIL 3 applications, the HFT is 1. Consequently, this extension cable is suitable for safety-critical machinery protection systems.

Installation Guidelines for the 330190-075-01-00

First, route the Bently Nevada 330190-075-01-00 away from high-voltage power cables to minimize noise pickup. Observe the minimum bend radius of 25.4 mm (1.0 inch) to avoid damaging the cable. Then, connect the extension cable between the 3300 XL Proximitor Sensor and the monitor. Hand-tighten the connectors to a maximum torque of 0.565 N•m (5 in•lbf). For armored cable installations, ensure the armor is properly grounded at one end only to avoid ground loops. Finally, verify the system gap setting at -9 Vdc (approximately 1.27 mm / 50 mils) for radial vibration measurements.
