Kromschroeder DG500B-3 (84447450) gas pressure switch

Kromschroeder DG500B-3 84447450 gas pressure switches designed to monitor changes in gas or air pressure, whether it’s increasing or decreasing.

Kromschroder 84447450 DG500B-3 gas pressure switch maintenance

To ensure smooth operation:

1. Verify the tightness and functionality of Krom schroder DG500B-3 84447450 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 DG500B-3 84447450 pressure switch technical data
