Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Signal drift or loss
Cause: Contamination buildup on sensing face (e.g., ferrous particles, scale) interfering with magnetic field detection, or degradation of internal electronics due to temperature cycling or moisture ingress.
False triggering or erratic output
Cause: External electromagnetic interference (EMI) from nearby motors, drives, or power lines, or physical misalignment/damage to the sensor or target affecting the magnetic coupling.
Maintenance Indicators
  • Intermittent or unstable readings on the connected monitoring system (e.g., PLC/DCS alarms for signal fluctuation)
  • Visible physical damage, corrosion, or excessive debris accumulation on the sensor housing or sensing face
Engineering Tips
  • Implement regular cleaning schedules for the sensor face using non-abrasive methods and ensure proper sealing/gaskets to prevent contamination and moisture ingress.
  • Install EMI shielding (e.g., conduit, ferrite cores) and maintain adequate separation from high-power electrical equipment; verify and secure sensor alignment during installation and routine checks.
