Kromschroeder DG18I-3 (84447050) gas vacuum sensor

Kromschroder DG18I-3 84447050 gas pressure switch designed for monitoring increasing and decreasing gas or air pressure.

Maintenance

In order to ensure smooth operation:

1. Check the tightness and function of Kromschroeder DG18I-3 84447050 differential pressure switch every year, or every six months if operated with biogas.
2. A function check can be carried out in case of decreasing pressure control e.g. with the PIA.
3. After carrying out the maintenance work, check for tightness.
