The Kromschroder DL pressure switch provides accurate, reliable monitoring of air pressure for industrial and commercial combustion systems, boilers, and HVAC systems. The DL can be used as a positive pressure switch, vacuum sensor or as a differential pressure switch for air, flue gas and other non-aggressive gases. It monitors extremely low pressure differentials and is not suitable for fuel gases.
The DL triggers switch-on, switch-off or switch-over if a set switching point is reached. The switching point can be adjusted by a hand wheel or an adjusting screw.
