Frequently Asked Questions (FAQ)
General & Technical
Is this probe compatible with my existing 3300 system?
Yes. It is a direct mechanical and electrical replacement for 3300 RAM probes.
What makes the NSv probe better?
It offers increased chemical resistance. This is vital for process gas compressors.
Selection & Ordering
How do I choose the right part number?
Match the suffix codes to your needs: thread type, length, cable, and approval.
Can this probe handle high temperatures?
Yes. It operates up to 177°C. Check the temperature schedule for your class.
Installation & Maintenance
What is the correct installation torque?
Finger tight only. Maximum torque is very low at 0.56 N•m (5 in-lb).
My shaft is smaller than 13mm. Can I use this probe?
Yes, but scale factor may change. Reduce the gap setting to minimize error.
How to Choose the Right Probe
- Verify system compatibility (3300 series monitor).
- Check mounting hole thread and required probe length.
- Select cable length to reach the junction box.
- Consider environment (chemicals, temperature).
