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. • Service: Water based liquids. • Low Flow Set Point: .4 m/s (1.2 fps) (water related) typical. • Temperature Set Point: 122°F (50°C) or 158°F (70°C), other settings possible on OEM demand. • Temperature Limits: -4 to 176°F (-20 to 80°C). • Response Time: 5 to 10 seconds. • Repeatability: 0.5%. • Hysteresis: <20% of set-point value. • Pressure Limit: 150 psi (10 bar). • Protection Class: NEMA 6 (IP 67). • Wetted Material: 303 SS. • Process Connection: 1/2" male NPT. • Electrical Connection: M12 male socket 4 pin with 6 ft (2 m) connection cable with M12 connector sold separately. • Power Requirement: 18-30 VDC. • Electrical Rating: <200 mA. • Power Consumption: 4 W max. • Initial Operation: After 15 seconds. • Switch Type: PNP N.O. (switch closes with flow).
