• Total Cable Weight: Approx 0.26 kg for 7.5m length.

Proximity Probe System Compatibility

The 330190-075-00-05 works with 3300 XL 8mm probes.

Linear Range:

• 2 mm (80 mils) total range.

• Linear range begins at approximately 0.25 mm (10 mils) from target.

• Full linear range: 0.25 to 2.3 mm (10 to 90 mils).

• Corresponding voltage: approximately -1 to -17 Vdc.

Recommended Gap Setting for Radial Vibration:

• -9 Vdc [approximately 1.27 mm (50 mils)].

Interchangeability Note:
3300 XL 8mm components are electrically and physically interchangeable with non-XL 3300 5mm and 8mm components. However, always observe the minimum permissible cable bend radius.

Field Wiring Guidelines

The 330190-075-00-05 connects to a Proximitor sensor. Use the following field wiring recommendations.

Wire Specifications:

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

• Recommendation: Use 3-conductor shielded triad cable.

• Wire Type: Tinned field wiring.

Maximum Field Wiring Length:

• 305 meters (1,000 feet) between the 3300 XL Proximitor sensor and the monitor.

High Frequency Note:
See the frequency response graphs for signal rolloff at high frequencies. Longer field wiring lengths reduce high frequency response.

Installation Guidelines

Install the 330190-075-00-05 between your 3300 XL Proximitor and the probe. Observe the minimum bend radius of 25.4 mm. Do not kink or crush the cable. Hand-tighten the connector to 0.565 N•m maximum. Do not use tools or over-torque. For hazardous area installations, follow ATEX/IECEx wiring methods. Keep the extension cable away from high voltage wires. Use shielded triad cable for field wiring extensions. The 330190-075-00-05 is not armored. Protect it from sharp edges and abrasion.

Frequently Asked Questions (FAQ)

1. What is the difference between standard and ETR cables?
The ETR cable uses PFA insulation instead of FEP. The 330190-075-00-05 operates from -52°C to +260°C. Standard cables only go to +177°C.

2. Can I use this cable with non-Bently proximity probes?
The 330190-075-00-05 has specific 75Ω triaxial impedance. It is optimized for Bently 3300 XL systems. Other probes may not provide accurate readings.

3. What happens if I exceed the minimum bend radius?
Exceeding 25.4 mm may damage the internal conductors. This changes the cable capacitance. The 330190-075-00-05 will then give inaccurate gap voltage readings.

4. Is this cable approved for Zone 1 hazardous areas?
The 05 approval option includes CSA, ATEX, and IECEx. Check your specific zone requirements. Typically, these approvals cover Zone 1 and Zone 2 installations.

5. How do I clean the connectors on this cable?
Use a lint-free cloth with isopropyl alcohol. Do not use abrasive cleaners. The gold plating on the 330190-075-00-05 connectors is thin and can wear off.
