FAQ

1. What is the sensing range of the 3300 XL 8mm probe?

The probe is designed for standard 8mm targets; the operating range depends on installation geometry but typically supports 0.38–2.5 mm gap measurement.

2. Can this probe be used in high-temperature environments?

Yes, it can operate in temperatures from -51°C to +177°C (-60°F to +351°F).

3. Is the probe armored for mechanical protection?

No, this model is unarmored; care must be taken in exposed installations.

4. Are the connectors compatible with previous 3300 series systems?

Yes, the ClickLoc connectors are backward compatible with older 3300 XL components.

5. What type of cable does the probe use?

The probe uses standard coaxial cable suitable for industrial signal transmission.

6. How robust is the probe tip?

The 8mm PPS plastic tip is mechanically reinforced for harsh environments, making it more durable than the 5mm version.

7. Is the probe suitable for hazardous area installations?

Yes, it is certified for ATEX, IECEx, and NEPSI hazardous locations.

8. What is the installation procedure?

Install the probe using the 3/8-24 UNF thread; tighten the ClickLoc connector until it clicks.

9. Can the cable length be customized?

Standard length is 9 meters; custom lengths require special order consideration.

10. What machinery types are ideal for this probe?

Ideal for turbines, compressors, generators, and other rotating equipment with fluid-film bearings.
