A Pressure Switch is a type of switch that closes an electrical connection when a certain set fluid pressure has been attained on its input. However, the usage of rubber diaphragms is refrained from using in mineral oil since it would degrade the inner parts of the pressure switch. Setra Systems has been designing differential pressure sensors for over 50 years. They are mainly used... A Differential Pressure Switch, just like a regular pressure switch, is a simple electro-mechanical device that operates on the basic principles of levers and opposite forces. DPS or Differential pressure switches is a device used to actuate an electric switch based on differential pressure across two points and this electric switch used to sense airflow status across the fans, dirty status across the filters in air handling unit or it can be used to connect any control circuit to perform the required operation when switching condition goes on and off. The bellows (4) and (24) are respectively connected to lower pressure port and higher pressure port. Switches operate by breaking or establishing an electric circuit in order to affect the power provided to an electrical device. Other advantages are better accuracy, high resistance to shock and vibration, broad frequency response, and long term stability. At low pressures, diaphragm and bellows movements are most often used. Differential pressure switches. Pressure Switch, Operat. A pressure switch comprises either one or two ports.
