Kromschroeder DG150BG-3 (84447420) gas pressure switch

Kromschroeder DG150BG-3 84447420 gas pressure switches for monitoring increasing and decreasing gas or air pressure.

Kromschroder 84447420 DG150BG-3 gas pressure switch maintenance

In order to ensure smooth operation:

• Сheck the tightness and function of the DG every year, or every six months if operated with biogas.
• A function check can be carried out in case of decreasing pressure control e.g. with the PIA.
• After carrying out the maintenance work, check for tightness.

Krom schroder DG150BG-3 84447420 pressure switch technical data
