Short Description :
The type 604 pressure switch is used as a Δp flow switch in
ventilation ducts for the control of filters and fans, and in
primary and secondary control systems for the control of air
dampers.
The 604 pressure monitoring switches are also ideally suited
to protect heating coils from overheating and for monitoring
industrial air cooling circuits. Product Detail :
