Professional Application Questions

• What applications need 90mm unthreaded length? This design suits installations requiring clearance before threading begins
• How does armor affect temperature performance? The armor maintains the same -52°C to +177°C range as unarmored versions
• Can I use this probe for axial position measurement? Yes, but maintain 13mm minimum shaft diameter for accurate scaling
• What makes the NSv probe chemically resistant? The PPS tip material withstands harsh process chemicals better than older probes
• How do I ensure proper signal quality over distance? Use shielded triad cable and follow the 305 meter maximum wiring guideline
