Providing proximity measurement in tight spaces, the Bently Nevada 330906-02-12-05-02-CN functions as a high-precision eddy current transducer designed for the 3300 NSv proximity transducer system. Engineered specifically for applications with narrow installation envelopes or thin target shafts, this reverse-mount probe delivers reliable dynamic vibration and static position feedback. The assembly features a robust polyphenylene sulfide (PPS) probe tip and an AISI 304 stainless steel case, ensuring excellent resistance to corrosive industrial environments and elevated process temperatures. Equipped with a FEP-insulated 75 ohm coaxial cable and a miniature coaxial ClickLoc connector, it maintains signal integrity across its 0.5-meter length without attenuation.

The 3300 NSv (Narrow Side view) system is specifically designed for situations where target shaft diameters are smaller than 50 mm (2 inches) or where side-clearance to conductive materials is extremely limited. Note that 3300 NSv probes are not interchangeable with standard 3300 XL 5mm or 8mm proximity probes. Combining a 3300 NSv probe with a standard 3300 XL Proximitor sensor driver will result in severe calibration errors and alter the system’s nominal 7.87 V/mm (200 mV/mil) scale factor.
When deploying reverse-mount probes, verify that the thread engagement into the machine casing or bracket does not twist or bind the integrated cable. A major failure point is cable sheath damage caused by rotating the entire probe assembly during installation without disconnecting or pre-looping the cable. Maintain a minimum bend radius of 25.4 mm (1.0 inch) for the FEP-insulated coaxial cable to avoid structural degradation of the internal conductor shield.
Always clean the miniature coaxial ClickLoc connectors with an approved residue-free electronic solvent before mating. Ensure that the mechanical latch clicks into place securely. To protect the connection from moisture, oil ingress, and electromagnetic interference in dirty industrial environments, wrap the mated connector assembly in self-fusing silicone tape or install a Bently Nevada connector protector kit.
Isolate and de-energize the machinery, monitoring rack, and sensor drivers prior to probe installation or physical adjustment. Do not exceed the maximum allowable tightening torque of the AISI 304 probe case to prevent structural distortion of the internal transducer windings or thread shearing.
Thread the reverse mount probe into the installation sleeve or mounting bracket from the back, ensuring the cable rotates freely to avoid torsional fatigue.
Connect the probe to an extension cable and monitor the gap voltage using a digital multimeter connected to the Proximitor sensor's OUT and COM terminals.
Adjust the mechanical depth until the gap voltage reads within the center of the linear range (typically -10 V DC for standard 3300 NSv systems).
Lock the assembly securely using the locknut, re-verify the gap voltage, and slide a protective sleeve over the ClickLoc coaxial connection.
