Frequently Asked Questions (FAQ)

• What applications suit this short-case probe? The compact 40mm case is perfect for machinery where mounting space is very limited.
• Is there a performance difference from longer probes? No. All 3300 NSv Probes share the same electrical specs and performance; only physical dimensions differ.
• How do I handle the pressure sealing? The probe has a Viton O-ring seal but is not factory tested for specific pressure applications.
