Mechanical Differential pressure switch 604
The pressure switches of Type 604 monitor filters and fans in ventilation ducts as well as air dampers in primary/secondary controls in Δp function. The series, divided into five pressure range gradations, impresses with extreme ease of installation, combination brackets, snap-on covers, and screw terminals. Unique is the high adjustment accuracy through individual scale engraving.
- Easy to install
- User-friendly snap closure for the cover
- Cable entry aid
- Cable strain relief integrated into PG11
- Combination bracket for vertical or horizontal mounting
- High adjustment accuracy through individual scale engraving per switch
- Long-term stable switching points through trapezoidal bead membrane
- Multilayer contact with gold plating
