Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Sensor Drift/Calibration Loss
Cause: Exposure to target gases, contaminants, or environmental conditions (temperature, humidity) causing chemical degradation or poisoning of sensing elements, leading to inaccurate readings.
Electronic Component Failure
Cause: Moisture ingress, thermal cycling, or power surges damaging circuitry, connectors, or the power supply, resulting in sensor malfunction or complete failure.
Maintenance Indicators
  • Persistent false alarms or failure to alarm at expected gas concentrations
  • Unusual display readings (e.g., constant values, erratic fluctuations, or out-of-range indicators)
Engineering Tips
  • Implement a strict, documented calibration schedule using certified test gases, and perform bump tests more frequently in harsh or high-exposure environments.
  • Ensure proper environmental protection: use appropriate enclosures (NEMA/IP-rated), maintain stable operating temperatures, and install in well-ventilated areas away from direct contaminants or condensation sources.
