TECHNICAL INFORMATION
FSW-410 SERIES
The safe sensing solution for industrial cooling systems.
The FSW-410 utilizes the calorimetric principle and the All-in-One
monitoring of flow and temperature of the coolant.
The FSW-410 is especially designed, for all types of cooling systems,
as a reliable alternative to failure prone mechanical flow switches.
Compact electronic unit with no moving parts
No adjustment or calibration needed
Maintenance free
Fail safe normally open switch
Easy to Install
