Technical Frequently Asked Questions

• Q: What is the recommended torque for the housing's dome cover?
  A: Typically, hand-tight plus a quarter-turn with a spanner is sufficient (approx. 15-20 ft-lbs). Always consult the manual.
• Q: Can this housing be used in submerged or high-humidity applications?
  A: Yes, the CSA Type 4 rating certifies it for watertight service when all seals are properly installed.
• Q: What is the expected service life of the integrated probe?
  A: With proper installation, the probe can operate reliably for 5+ years in typical industrial environments.
• Q: Is the 5.0-inch penetration suitable for measuring thrust position?
  A: Yes, this length is common for mounting on compressor casing for axial displacement monitoring.
• Q: Do you provide calibration certificates with the housing assembly?
  A: The probe includes factory calibration. A formal calibration certificate may be available as an optional add-on.
