Expert FAQ on the 3300 XL 8mm Probe

• Q: Does this 1.0-meter probe model require special agency certifications?
  A: The 330102-00-64-10-02-00 comes without agency approvals ("00" option), making it ideal for standard, non-hazardous industrial areas.
• Q: What is the benefit of the longer 6.4-inch case length on this probe?
  A: It allows installation through thicker machinery casings or mounting brackets for deeper reach to the measurement target.
• Q: How does the Viton O-ring seal function in this probe's design?
  A: It seals the internal cavity, protecting the sensing element from external pressure differences and contaminants.
• Q: Can I use this probe in very cold environments below -34°C?
  A: We do not recommend it, as temperatures below -34°C (-30°F) may compromise the integrity of the pressure seal.
• Q: What makes the 3300 XL system's -9 Vdc gap setting the industry standard?
  A: It positions the operating point in the center of the linear range, allowing equal measurement of vibration peaks in both directions.
