How to identify faulty sensors and manage their impact

Electrical surges, environmental extremities (such as excessive dust, noise, smoke or vibration) and simple aging are just a few of many reasons sensors fail.

Ideally, all sensors in a building should be connected to the building management system. Through the BMS, you can find whether the sensor is functioning, and you can capture the reading or output of the sensor. However, this most likely will not give you any indication as to the reading’s accuracy.

You can detect and diagnose sensor accuracy problems in three methods: physical inspection, statistical comparison and online fault detection and diagnostic.

  1. Physical inspection
  2. Statistical comparison
  3. Online sensor fault detection and diagnostic
