Pressure Switch gas Krom-schroder type DL3A-3 (0.2 to 3.3mbar)

Pressure Switch gas Krom-schroder type DL3A-3 (0.2 to 3.3mbar)

Kromschroder Pressure Switch (0.2 to 3.3mbar) for air CPS can be used as excess pressure, negative pressure and differential pressure switches for air and other non-flammable gases. They monitor extremely slight pressure differences and trigger switch-on, switch-off or switch-over operations if a set value is reached. Fields of application include air flow monitoring, fan monitoring or filter monitoring on intake and extract ventilation systems, on air-conditioning systems and in kitchens, frost-protection control on heat exchangers and closed-loop control of butterfly valves for air and fire dampers. The pneumatic and electrical connections are accessible from the same side in order to ensure space-saving installation.
