Five professional FAQs

• Q: Which signal conditioner suits CA202 best?
  A: Use a charge converter or IPC70x family for best bandwidth and stability.
• Q: How do I ground the sensor in noisy plants?
  A: Tie sensor case to the plant ground at one point only to reduce loops.
• Q: Can I shorten the integral cable on site?
  A: You can shorten it. Use proper sealing and re-welded termination for hermeticity.
• Q: How often should I check calibration?
  A: Verify calibration yearly for continuous monitoring systems under heavy load.
• Q: What mounting surface finish do you recommend?
  A: Use a clean, flat steel surface with Ra < 3.2 µm and correct torque.
