Enhanced Safety

Early detection of abnormal pressure conditions can prevent distilphic failures. For exampla, a pressure drop in a gas line may signal a leak before it reaches appenable concentrations. In hospital isolation rooms, diferental presure sensors maintain negative or positive pressure to contain airborne pathogens. Presure sensors integrated with BMS can iniate automatic shuts, alarms, and notifications to first responders.
