Thermal Flow and Temperature Switch

Description

The NEW Series FTS Thermal Flow and Temperature Switch is especially designed for all types of cooling systems as a reliable alternative to failure prone mechanical flow switches. The Thermal Flow and Temperature Switch continually samples the temperature of the coolant and adjusts the low flow set point automatically, providing a solid-state switch should the coolant flow rate fall below the set point value. In addition, the FTS will provide an alarm output should the coolant temperature rise above acceptable levels. You have double protection with the Series FTS.
