Professional FAQ

How does the 330191-00-08-05-00 probe differ from the 330191-40-75-05-05 model?

Reference the [330191-40-75-05-05 model] for comparison; the main differences include cable length, armor, and extended temperature options.

Can the probe operate in high-vibration environments?

Yes, the 8 mm PPS tip and larger stainless steel case offer superior robustness against mechanical stress and physical abuse.

What is the maximum temperature the probe can handle?

Depending on EPL classification, the probe supports T1 up to +232°C and T5 up to +40°C.

How does the FluidLoc cable option benefit performance?

FluidLoc prevents oil or fluid leaks through the probe cable, maintaining signal integrity in liquid-exposed environments.

What installation precautions should be taken for optimal probe performance?

Ensure proper thread engagement, avoid over-torquing connectors, and use TipLoc/CableLoc features to secure probe and cable connections firmly.
