Frequently Asked Questions
Product Selection & Use
Q: What is the main advantage of the 9-meter cable length?
A: It allows installation on large machinery where the monitor is far from the measurement point, reducing the need for extension cables.
Q: Can this probe measure both vibration and position?
A: Yes. When connected to a compatible Bently Nevada monitor system, it can measure radial vibration or axial position (thrust).
Installation & Compatibility
Q: What does “without armor” mean for the cable?
A: The cable has a standard FEP jacket instead of a braided stainless steel overjacket. It is suitable for general industrial use without extreme abrasion risk.
Q: Is this probe compatible with older Bently Nevada systems?
A: Yes, the 3300 XL 11 mm probes are designed for compatibility with 3300 XL monitoring systems. Check your system manual for specific requirements.
Technical & Purchasing Advice
Q: The probe resistance is 8.5Ω. Is this normal for a 9m cable?
A: Yes. Resistance increases with cable length. This value (8.5Ω ±1.1Ω) is the expected and correct specification for a 9-meter probe.
