Frequently Asked Questions (FAQ)

What is the main advantage of the 8mm probe design?

The 8mm body is thicker and much stronger. It protects the internal coil better. This makes it ideal for tough environments where probes might get hit or scratched.

How do I choose between a standard and a FluidLoc cable?

This model (-02) has a standard cable. Choose a model with a -12 suffix if your machine has oil or coolant that could leak into the cable path.

What is the "Recommended Gap Setting" and why is it -9 VDC?

This is the best starting point for vibration measurement. A -9 VDC gap (about 1.27 mm) centers the measurement in the probe's linear range. This gives you the best accuracy for vibration signals.

Can I use this probe for thrust position measurement?

Yes. The same 3300 XL 8mm probe works for both vibration and position. You just set a different gap voltage (like -12 VDC) for the axial position measurement.

What is the difference between Standard and Extended Temperature Range probes?

Standard probes work from -52°C to +177°C. Extended Range probes have special materials. They work up to +218°C at the tip. This model is the Standard temperature version.
