FAQ

Can the probe handle rapid temperature changes?

Yes, the ceramic tip and stainless steel case maintain stability across thermal cycles.

How do I select the correct cable length?

Choose -90 for 9m when monitoring distant targets, shorter lengths reduce signal attenuation.

Is this probe suitable for high-pressure applications?

Yes, rated to 34 Bar; custom modifications are available for higher pressures.

What maintenance is recommended for long-term accuracy?

Keep connectors clean and inspect thread engagement regularly.

Which systems are fully compatible with this probe?

Only 3300 XL series components ensure accurate linearity and interchangeability.
