HUBA604 Mechanical Pressure Switch

Relative and differentialpressure switch type 604Pressure range0.2 ... 3 50 mbarThe type 604 pressure switch is used as a Δp flow switch in ventilationducts for the control of filters and fans, and in primary andsecondary control systems for the control of air dampers.The 604 pressure monitoring switches are also ideally suited toprotect heating coils from overheating and for monitoring industrialair cooling circuits. Easy to install User friendly snap fir cover Case geometry allows easy cable lead-in Cable strain relief integrated in PG11 Combi-bracket for vertical or horizontalinstallation High adjustment accuracy throughindividual laser etched scale Long-term stability of switching pointsthrough trapezoidal bead diaphragm Multi-layer gold plated contactHuba Control type 604 - Technical data subject to change - Edition 11/2011 1/5
