Frequently Asked Questions (FAQ)

Product Selection & Compatibility

Q: Is this probe compatible with my existing Bently Nevada system?

A: Yes, this 3300 XL probe works with standard 3300 series monitors. Check your monitor’s manual for specific channel requirements.

Q: How do I choose between 1m, 5m, and 9m cable lengths?

A: Select the length that reaches from the measurement point to the monitor with minimal slack. Avoid coiling excess cable tightly.

Installation & Use

Q: What is the correct installation torque for the probe body?

A: Use the recommended torque of 15.2 N•m (133 in•lb). Do not exceed the maximum of 45.2 N•m to avoid damage.

Q: Can I use this probe in high-pressure environments?

A: The probe has a Viton O-ring seal. It is not pressure tested before shipment. For high-pressure applications, contact our sales team for a custom solution.

From Our Engineers’ Experience

Q: What is a common mistake during probe installation?

A: Overtightening the connector is common. It only needs to be finger-tight. Overtightening can damage the connector threads and affect signal quality.

Q: The probe readings seem unstable. What should I check first?

A: First, inspect the probe tip and target surface for cleanliness. Then, check the cable for damage or kinks, especially near connectors and bends.
