Frequently Asked Questions

• Q: What are the key differences in the 330101-00-84-20-02-CN configuration?
  A: This model features an 8.4-inch case length (-84) and 2.0-meter cable (-20), providing more mounting flexibility and reach.
• Q: Why should I choose an 8mm probe over smaller diameter options?
  A: The 3300 XL 8mm Probe offers superior durability with thicker encapsulation and stronger construction for harsh environments.
• Q: What is the probe resistance for this 2.0-meter cable version?
  A: The nominal DC resistance is 7.88 Ω ± 0.5 Ω, slightly higher than the 1.5-meter version due to longer cable.
• Q: Can this probe withstand wet or humid environments?
  A: Yes, it shows less than 3% sensitivity change when tested in 93% humidity for extended periods according to IEC standards.
• Q: What installation precautions should I take with this probe?
  A: Follow torque specifications (11.2 N•m max), limit thread engagement to 0.563 inches, and avoid temperatures below -34°C to protect the pressure seal.
