▶ FAQ – Frequently Asked Questions

• Q: Can I use this probe in a high-pressure zone?
  A: The probe seals differential pressure but we do not pressure test each unit. Please contact us for testing.
• Q: What is the recommended gap for radial vibration?
  A: Set the gap to -9 Vdc, which equals approximately 1.27 mm (50 mils) from the target.
• Q: Does the probe work with 3300 XL Proximitor sensors?
  A: Yes, this probe fully matches the 3300 XL series Proximitor sensors.
• Q: What is the maximum length of field wiring?
  A: You can run up to 305 meters (1,000 feet) between the Proximitor sensor and monitor.
• Q: Which connector type does this model use?
  A: It uses a miniature coaxial ClickLoc connector with standard cable.
