FAQ

Q1: What is the main difference between the 25 mm probe and smaller range probes in the 3300 XL series?

A1: The 25 mm probe provides a larger linear measurement range, making it more suitable for machines with larger shaft movements compared to 8 mm or 11 mm probes.

Q2: Can this probe be directly connected to a monitor without an extension cable?

A2: No, it requires use with the appropriate extension cable and proximity sensor driver to function correctly.

Q3: Is the probe affected by temperature variations during operation?

A3: The probe is designed with compensation to minimize errors, ensuring accurate measurements across its specified temperature range.

Q4: What type of targets can the probe measure effectively?

A4: The probe is optimized for metallic targets, typically high-quality steel shafts as per API 670 standards.

Q5: Does the probe require calibration in the field?

A5: Factory calibration is provided, but system verification during installation is recommended to ensure accuracy.

Q6: Can multiple probes be installed on the same machine shaft?

A6: Yes, multiple probes are commonly used at 90° orientations for vibration and position monitoring.

Q7: What is the output signal format of the probe system?

A7: The probe outputs a voltage proportional to the gap distance, typically 200 mV per mil of shaft displacement.

Q8: How does the probe handle electrical noise in industrial environments?

A8: The 3300 XL series incorporates advanced shielding and grounding to minimize susceptibility to EMI/RFI interference.

Q9: Can the probe be used in hazardous area environments?

A9: Yes, with appropriate system certifications and installation practices, it can be applied in hazardous environments.

Q10: What is the maximum cable length supported in this system?

A10: Depending on configuration, up to 9 meters total length (probe + extension cable) can be used without loss of accuracy.
