Technical FAQs
Q1: What is the primary function of this probe?
It continuously measures shaft vibration and shaft displacement without physically touching rotating components.
Q2: What does NSv mean?
NSv stands for Narrow Side View, a design that minimizes sensitivity to nearby metallic surfaces.
Q3: Is this probe suitable for compact machinery?
Yes. The NSv series was specifically developed for installations where standard probes may not fit properly.
Q4: What does the "22" configuration indicate?
It designates a 2.2-inch unthreaded probe length.
Q5: What does the "40" configuration represent?
It refers to a 4.0-inch overall probe case length.
Q6: What cable length is included?
This configuration includes a 1.0-meter cable assembly.
Q7: Can different NSv components be mixed together?
No. The probe, extension cable, and Proximitor sensor must always be properly matched as a complete transducer system.
Q8: Which industries commonly deploy this product?
Oil and gas, petrochemical, power generation, refrigeration, and industrial manufacturing industries frequently utilize this technology.
Q9: What installation advice is most important?
Ensure the probe is correctly positioned relative to the shaft and not reading nearby mounting hardware.
Q10: What routine maintenance is recommended?
Inspect cable integrity, verify probe gaps, confirm mounting security, and periodically validate system performance.
