FAQ

Q1: What is the typical use of the 330105-02-12-50-02-00 probe?

A1: It is typically used in rotating equipment for vibration and position monitoring, especially in hard-to-access reverse-mount scenarios.

Q2: Can the probe operate in hazardous areas?

A2: Yes, it is certified for hazardous locations including ATEX Zone 0/1 and CSA Class I, Div 2.

Q3: Is the probe compatible with non-XL series components?

A3: Yes, it is both electrically and mechanically compatible with legacy 3300 5 mm and 8 mm components.

Q4: What material is used for the probe tip?

A4: The probe tip is made of PPS (polyphenylene sulfide) for chemical and temperature resistance.

Q5: Does the system require calibration before installation?

A5: No, all components are fully interchangeable and factory-calibrated, requiring no bench calibration.

Q6: Can this probe measure both vibration and position?

A6: Yes, it is designed for dual-purpose measurements—both dynamic vibration and static position.

Q7: What is the recommended probe gap setting?

A7: The standard gap setting is approximately -9 Vdc, corresponding to 1.27 mm (50 mils).

Q8: What’s the pull strength rating of the probe cable?

A8: It supports up to 330 N (75 lbf) from the probe case to the probe lead.

Q9: What is the probe’s operating temperature range?

A9: Standard probes operate from -52°C to +177°C; ETR versions up to +218°C.

Q10: Is the cable bend radius limited?

A10: Yes, the minimum bend radius is 25.4 mm (1.0 in) to maintain signal integrity.
