Frequently Asked Questions

Product Differences

Q: What is the main difference between 3300 XL and 3300 NSv probes?

A: The NSv series often uses Imperial threads like 1/4-28 UNF. The XL series commonly uses metric M10x1 threads.

Q: Why would I choose a 2-inch case length?

A: A 2-inch case provides a standard, versatile length. It fits many common mounting arrangements in pumps and motors.

Installation & Use

Q: What is the correct way to torque this probe?

A: Use a torque wrench. Tighten to the recommended 100 in-lbs. Do not exceed 300 in-lbs to avoid damage.

Q: How do I handle the probe in cold weather?

A: Avoid installing it below -34°C (-30°F). This low temperature can harm the internal pressure seal permanently.

Ordering & Logistics

Q: What does your service include for the 330901-10-20-10-02-05?
