Pressure switches for air DL can be used as positive pressure switches, vacuum sensors or differential pressure switches for air, flue gas and other non aggressive gases. They are not suitable for fuel gases. They monitor extremely low pressure differentials.
They trigger switch-on, switch-off or switch-over operations if a set switching point is reached. This switching point can be adjusted using a hand wheel or, if required, it can be fixed using an adjusting screw.
The diaphragm pressure switch with micro switch features particularly high contact reliability as low gas release components are used.
DL..A, DL..K are used for controlling butterfly valves for air and fire dampers in firing systems, and for fan monitoring.
