The Honeywell Kromschroder DL pressure switch provides accurate, reliable monitoring of air pressure for industrial and commercial combustion systems, boilers, and HVAC systems.

The Honeywell 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.
