Kromschroder Pressure sensor DG 10UG-4 84447010

The Kromschroder DG 10UG-4 is a pressure switch (SKU 84447010) manufactured in Germany. It is designed for gas pressure monitoring in gas supply systems of burners, boilers, heat generators, and industrial heating equipment. The switch provides accurate monitoring and instant response when pressure deviates from set parameters, ensuring system safety. It is suitable for replacement in existing gas systems and complies with European safety standards.

Parts of this type are selected by the medium (air or gas), the required switching range and differential, the type of connection (thread or hose spigot), contact rating, and applicable approval class. Before ordering, verify that the replacement matches the original in these parameters. Ensure the impulse line is clear and correctly routed during installation.

Typical failures include a torn diaphragm, a blocked impulse tube, or a drifted setpoint. These often cause burner lockouts that can be mistaken for ignition problems. Check the diaphragm, impulse line, and setpoint adjustment when such symptoms occur.
