FAQ

Q1: What is the typical sensitivity of the 3300 XL 8 mm probe?

A1: The probe provides a sensitivity of approximately 7.87 V/mm (200 mV/mil).

Q2: Can the probe be used with both 5 mm and 8 mm proximitor sensors?

A2: This model is designed for use with 8 mm proximitor sensors; it is not recommended to mix probe and proximitor types.

Q3: What is the maximum linear range of this probe?

A3: The linear range is typically 2 mm (80 mils).

Q4: How is the probe signal transmitted to the monitoring system?

A4: The probe transmits its signal through an extension cable to the proximitor sensor, which conditions the signal for monitoring systems.

Q5: Does cable length affect calibration?

A5: Yes, probe, extension cable, and proximitor sensor must be matched as a calibrated system. Using different lengths or mismatched components can affect accuracy.

Q6: What is the effect of temperature on probe performance?

A6: The probe is temperature-compensated for its specified range (-35 °C to +177 °C) to maintain measurement accuracy.

Q7: What type of thread is used for mounting?

A7: It is available in either M10 × 1 or 3/8-24 UNF, depending on the configuration ordered.

Q8: Can the probe be used in hazardous environments?

A8: Yes, it can be used in hazardous areas when paired with certified proximitor sensors that meet ATEX/CSA standards.

Q9: What is the electrical grounding requirement?

A9: The probe system requires proper grounding of shielded cables and proximitor sensors to minimize noise interference.

Q10: How does this probe compare to the 5 mm variant in terms of performance?

A10: The 8 mm probe offers greater linear range and robustness in harsh environments, while the 5 mm probe is more suitable for tight installation spaces.
