Installation Guidelines

Follow these steps to install your Bently Nevada 330190-080-00-CN extension cable correctly.

1. Inspect the Cable – Check for cuts, kinks, or damage to PFA insulation.

2. Plan the Route – Keep bend radius larger than 25.4 mm (1.0 in).

3. Connect to Proximitor – Attach one end to the 3300 XL Proximitor sensor.

4. Connect to Monitor – Attach the other end to the monitoring device.

5. Secure the Cable – Use non-metallic cable ties every 0.5 meters.

6. Tighten Connectors – Apply maximum 0.565 N•m (5 in•lbf) torque.

7. Keep Away from Heat – Route away from high temperature surfaces.

8. Verify Continuity – Check resistance values match specifications.

Do not exceed 0.565 N•m connector torque. Overtightening will damage gold-plated connectors.

Bend Radius Requirements

Field Wiring Extension

When extending beyond the 8.0 meter cable, observe these limits.

Frequently Asked Questions (FAQ)

1. What is the difference between standard and ETR extension cables?
The ETR cable uses PFA insulation instead of FEP. This extends the maximum temperature rating from +177°C to +260°C.

2. What is the length of the Bently Nevada 330190-080-00-CN cable?
This cable measures 8.0 meters (26.2 feet). The -080 option specifies the 8.0 meter length.

3. Can I use this cable with non-XL 3300 components?
Yes. 3300 XL 8 mm components are electrically and physically interchangeable with non-XL 3300 5 mm and 8 mm components.

4. What is the minimum bend radius for the 330190-080-00-CN?
The minimum bend radius is 25.4 mm (1.0 inch). Sharper bends will damage the triaxial cable construction.

5. What functional safety ratings does this cable support?
This cable supports SIL 2 with HFT=0 and SIL 3 with HFT=1. Use appropriate system architecture for your safety level.

6. How far can I extend field wiring beyond this cable?
You can extend up to 305 meters (1,000 feet) total between the Proximitor sensor and monitor. Use 3 conductor shielded triad cable.

Why Choose This Model?
