Distinctive Sensor Parameters for Predictive Maintenance

Smart Industry

Environmental sensing use casesCondition-based Monitoring Examples

Environmental sensors play critical roles in industrial applications

Pressure measurements for "air management” systems, whichmonitor the performance

indicators and the different stages of the air compressors connected to the compressed-air supply grid

Largely adopted in HVACsystem control water vapor Level or to help in regulating

parameters such as air temperature and blowing speed.

Measure operating temperatures, It’s useful fordetecting loose or improperly

terminated electrical connections, overloading, defective contacts, phase imbalances and other electrical problems.
