Frequently Asked Questions

Q1: What is the main difference between the 330710 model and an 8 mm probe?

A1: The 330710 features an 11 mm tip, which provides a longer linear measurement range and better gap stability than standard 8 mm probes. This makes it more suitable for larger shaft applications.

Q2: Can I use this probe with an existing 3300 XL extension cable?

A2: Yes, the 330710-004-054-50-02-00 uses a standard miniature coaxial ClickLoc connector. Therefore, it is fully compatible with all 3300 XL series extension cables and proximity systems.

Q3: What is the recommended target material for this probe?

A3: This probe is calibrated for use with AISI 4140 steel or equivalent ferrous materials. Using different target materials may require a custom calibration to ensure accuracy.

Q4: How do I verify if the probe is working correctly after installation?

A4: You can check the output voltage with a multimeter while adjusting the gap. A static output voltage change of approximately 3.94 V per mm indicates proper functionality. Additionally, the system indicator light should show a stable reading.

Q5: Is this probe suitable for submersible applications?

A5: The probe body is sealed and can withstand high pressure up to 20.7 MPa. However, it is not designed for continuous submersible operation in conductive liquids. For such cases, please consult your application engineer.
