SENSOR FAULT Schneider Electric — Sensor Drift on Water Circuit
At a glance
- Severity
- WARNING
- Domain
- CHILLED_WATER_SYSTEM
- Reference standard
- EN 50600-3-1 / ISO 50001
What it means
Out-of-calibration temperature and pressure sensors: control acts on non-real values, wasting energy and producing false alarms that erode trust in supervision.
Probable causes
- Drift from aging or dirt
- Wrong positioning (sensors in non-representative points)
- No periodic calibration
- Non-redundant sensors on critical points
Where to start
Compare readings with reference instruments on the same points and between peer sensors (supply/return of both chains).
