Field Wiring Recommendations

Proper field wiring is essential for optimal system performance with the 330190-085-01-CN.

Specifically, use 0.2 to 1.5 mm² (16 to 24 AWG) tinned field wiring. We recommend using 3-conductor shielded triad cable for best results. The maximum length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). However, please consult the frequency response graphs for signal rolloff at high frequencies when using longer field wiring lengths.

• RoHS Directive: 2011/65/EU

• Maritime: ABS Rules for Classification (2019)

• Functional Safety: SIL 2 (HFT=0), SIL 3 (HFT=1)

Additionally, the CN suffix indicates this cable is specifically approved for use in China, simplifying customs clearance and regulatory compliance for domestic projects.

Installation Guidelines

Proper installation ensures reliable performance from your Bently Nevada 330190-085-01-CN.

First, inspect the cable for any visible damage before installation. Next, ensure the minimum bend radius of 25.4 mm is maintained throughout the routing path. The armored construction provides flexibility while protecting internal conductors.

Then, connect the cable to the proximity probe and Proximitor sensor using the gold-plated connectors. Apply the specified torque of 0.565 N•m to ensure proper connection. After that, secure the cable using appropriate clamps or supports to prevent movement. Finally, verify the system gap setting is at -9 Vdc (approximately 1.27 mm) for radial vibration applications.

Frequently Asked Questions (FAQ)

1. What is the difference between standard and extended temperature range cable?
The 330190-085-01-CN uses PFA insulation rated for -52°C to +260°C, while standard cable uses FEP insulation rated only to +177°C. This ETR version is ideal for high-temperature applications.

2. Can this cable be used with non-XL 3300 probes?
Yes, the 330190-085-01-CN is electrically and physically interchangeable with non-XL 3300 5 mm and 8 mm components when the minimum bend radius is observed.

3. What does the CN suffix indicate?
The CN suffix means this Bently Nevada extension cable carries China country approval, ensuring compliance with Chinese regulatory requirements.

4. What is the maximum field wiring length I can use?
The maximum length between the Proximitor Sensor and the monitor is 305 meters (1,000 feet). However, check the frequency response graphs for signal rolloff at longer lengths.

5. Is this cable suitable for SIL-rated safety systems?
Yes, the 330190-085-01-CN supports SIL 2 (HFT=0) and SIL 3 (HFT=1) functional safety applications.
