The Siemens Differential pressure switches are utilized in ventilation and air conditioning systems to monitor differential, under and over pressure in cleanrooms, kitchens, filters, and ductwork. They detect slight pressure differences across ducts, fans, or filters triggering alarms or control actions when preset thresholds are reached such as indicating torn fan belts, airflow disruptions, or clogged filters.
