Functional Features The NSv probe features superior side-view characteristics compared to standard probes, allowing installation in confined spaces with counter bore, sideview, or rearview restrictions. The 5 mm tip diameter is ideal for small target applications such as shafts smaller than 51 mm diameter. The armored cable provides protection against abrasion and crushing. The probe is fully interchangeable with other 3300 XL NSv system components.
Application Scenarios Centrifugal air compressor monitoring, refrigeration compressor vibration measurement, process gas compressor shaft monitoring, small pump radial vibration measurement, motor bearing monitoring, gear-driven equipment condition monitoring, installations with tight side-view clearance requirements.
Performance Parameters The probe delivers 7.87 V/mm sensitivity with a linear range of 1.5 mm. The system maintains stable performance across the full operating temperature range. The armored construction adds mechanical durability without compromising signal quality. The probe is backward compatible with 3300 RAM system components.
Material Composition Probe tip is polyphenylene sulfide (PPS). Probe case is AISI 304 stainless steel. Cable is 75 Ω triaxial with FEP insulation. Armor is flexible stainless steel. Connector material is gold-plated brass.
Structural Characteristics The probe features 1/4-28 UNF thread with a compact 4.0 inch case length. The 0.0 inch unthreaded length means the thread extends fully to the probe shoulder. The armored cable has an increased outside diameter for mechanical protection. The probe comes with a locknut for secure mounting.
Working Principle The probe operates using eddy current proximity sensing. An RF signal from the Proximitor Sensor creates an electromagnetic field at the 5 mm probe tip. Eddy currents induced in the conductive target surface cause a measurable impedance change. The Proximitor Sensor converts this into a DC voltage directly proportional to the gap distance.
