KROMSCHRODER - 84447500 30-150 MBAR GAS PRESSURE SWITCH DG150U-3 (84447500/84447516)

Gas Pressure Switch

The DG150U gas pressure switch from Kromschroder, monitors extremely low-pressure differentials and triggers switch-on, switch-off or switch-over operations when a user adjustable set switching point is reached.  Suitable for positive pressure, negative pressure and differential pressure measuring. The pressure switches can be installed vertically or horizontally.

Designed to provide excellent performance, this gas pressure switch actively monitors positive and negative gas pressures of a wide range of industrial gas and air appliances. Typical applications include gas deficiency monitoring, systems leak tightness checking, differential pressure monitoring such as boiler fan monitoring and differential pressure monitoring, negative pressure monitoring in multiple systems.
