330730-040-03-00 is a Bently Nevada eddy current application module featuring a flexible stainless steel armor and an integrated fluorosilicone connector protector. Fully compatible with 3300 XL 11mm transducer loops, this unit works seamlessly with industrial machinery monitoring systems to deliver flexible routing, rugged mechanical casing protection, and stable long-range proximity data communication.
Applications
Axial (thrust) position monitoring in rotating machinery to ensure proper shaft alignment and stability.
Steam turbine expansion measurements, including ramp differential expansion for thermal behavior analysis.
Reciprocating compressor rod position or rod drop detection for condition monitoring and fault prevention.
Tachometer and zero-speed measurement for accurate speed tracking during startup and shutdown.
Phase reference (Keyphasor) signals used in vibration analysis and machinery diagnostics.
Competitive Advantage
Extended Linear Range: The 11 mm tip provides a longer linear measurement range, making Bently Nevada 330730-040-03-00 ideal for thrust, expansion, and rod position monitoring.
High Signal Accuracy: Delivers 3.94 V/mm (100 mV/mil) output for precise non-contact vibration and displacement measurements in fluid film bearing machines.
Robust Mechanical Design: Features TipLoc and CableLoc technologies with strong pull strength and secure ClickLoc connectors to ensure reliable long-term operation.
Enhanced Environmental Protection: Optional FluidLoc cables and connector protectors improve resistance to oil, moisture, and harsh industrial conditions.

Installation & Troubleshooting FAQ
Q1: How do I lock the gold-plated coaxial connectors together without damaging the internal conductors?
A: Align the male pin connector with the female cable receptacle socket and push them together firmly until you feel or hear an audible mechanical click. These gold-plated brass ClickLoc connectors require only finger-tight torque to seal, and the engineering locking layout prevents loosening under severe machinery vibration without using wrenches.
Q2: Why is the proximity monitoring system logging an inaccurate loop calibration or a warped scale factor?
A: This error is almost always caused by an incorrect total line length mismatch. The combined length of the proximity probe cable and this extension cable must add up to exactly the calibrated matching total length of the 3300 XL Proximitor Sensor (typically 5.0 meters or 9.0 meters). Verify your lengths, avoid splicing lines, and ensure all shared bus junctions are clean.
Q3: What are the exact physical bend radius limits and routing rules for this armored cable variant?
A: To prevent kinks or micro-fractures in the FEP insulated internal layers, you must maintain a minimum physical bend radius of 25.4 mm (1.0 inch) along the routing path. Avoid running lines alongside high-voltage motor supply feeds, and use the integrated connector protector to block airborne moisture or conductive fluids from touching the core gold contacts.
