Kromschroeder DG150U-5 (84447506) gas pressure switch

Kromschroeder DG150U-5 84447506 gas pressure switches designed to monitor changes in gas or air pressure, whether it’s increasing or decreasing.

Maintenance of Kromschroder 84447506 DG150U-5 gas pressure switch

To ensure smooth operation:

1. Verify the tightness and functionality of Krom schroder DG150U-5 84447506 gas pressure switch annually, or every six months if it operates with biogas.
2. Conduct a functional check, particularly for decreasing pressure control, for example, using the PIA.
3. After performing maintenance work, ensure to check for any leaks in the system.

Krom schroder DG150U-5 84447506 pressure switch technical data

Adjusting range: 30-150 mbar

Gas type: natural gas, town gas, LPG (gaseous), flue gas, biogas (max. 0.1 %-by-vol. H2S) and air

Switches with rising positive pressure (gas/air), negative pressure (air), differential pressure (air-air)
