Product Overview
Bently Nevada 330906-02-12-10-02-CN is a 3300 NSv reverse mount proximity probe designed for vibration and shaft displacement monitoring in compact rotating machinery. It is typically used in auxiliary turbines, compressors, and pump systems where reverse installation geometry is required due to restricted mounting access.
The reverse mount design allows installation from the opposite direction of standard probe orientation, improving flexibility in dense mechanical assemblies. The NSv architecture maintains stable signal response in constrained environments while preserving compatibility with Bently Nevada monitoring systems.
The 1.0 meter cable configuration supports standard routing in industrial control layouts with moderate distance between probe and monitoring module.
CN approval configuration supports deployment in regulated hazardous environments with regional certification requirements.

Technical FAQs
What is a reverse mount probe used for?
It is used when standard probe access is blocked or limited by machine structure.
Is it compatible with standard NSv systems?
Yes. It follows NSv electrical and mechanical interface standards.
Does reverse mounting affect signal accuracy?
No. Measurement performance remains unchanged if installation gap is correct.
Is CN approval required for all installations?
Only for hazardous or regulated industrial environments.
Installation & Field Engineering Notes
Ensure probe alignment is verified during installation due to reverse mounting geometry.
Maintain proper gap calibration after installation to ensure linear response accuracy.
Avoid cable tension near connector to prevent long-term mechanical stress.
Use proper grounding and shielding to reduce EMI influence in industrial environments.
