Available from Control Components , Kayden Classic 800 Series thermal dispersion flow switches provide the ultimate performance and features package for flow, level, interface, and temperature sensing.
Combining precision welding, highly accurate sensors, extremely rugged enclosures, and advanced digital electronics, the Classic 800 Series of thermal dispersion flow switches features the failure resistance inherent in the company's thermal dispersion technology and the performance and features one would expect from a much more expensive instrument.
With the Kayden Classic 800 series of thermal dispersion flow switches, users can select their choice of operation by simply pushing a few buttons. Thanks to their universal power input capability, these flow switches have the flexibility to be used in all power input situations.
Classic 800 series thermal dispersion flow switches use an advanced microprocessor to perform continuous self-test diagnostics on the electronics and the sensor elements. Any open or shorted connection will result in a FAULT indication that also opens all output contacts and disables the heater circuitry.
An internal watchdog circuit ensures that the microprocessor code is performing as expected and a secondary external watchdog circuit ensures that the microprocessor itself is functioning. In the event of a malfunction both circuits force the contacts open, illuminate the fault LED and force the heater off. This prevents the possibility of a “run-away” heater or a high thermal offset.
The Kayden Classic 800 Series of thermal dispersion flow switches also feature a range of intelligent user controls, including:
- a display panel with bright LED indicators for easy viewing even in direct sunlight
- an adjustable power on start up bypass timer accessible from the display panel for low flow alarm pump protection applications
- four adjustable delay timers that allow the introduction of repeatable time delay into the relay trip function.
