FAQ — Technical Insights

• How can I check compatibility with older Velomitor sensors?
  Verify connector type and sensitivity rating; older 330500 sensors fit directly.
• Can this housing operate in outdoor refineries?
  Yes, stainless steel and IP65 rating protect against water and dust exposure.
• What happens if the cable gland is not sealed properly?
  Ingress protection fails, possibly causing corrosion or false vibration signals.
• Does orientation affect reading accuracy?
  Yes, install the sensor vertically for optimal sensitivity and linearity.
• How can I reduce installation noise interference?
  Use shielded cables and bond housing to ground; avoid routing near power lines.
