The Kayden Classic 810 flow switch from Telematics Controls is configurable for flow, level, interface (liquid and slurry) and temperature applications. It only actuates when specific and preset interface conditions are met. The device uses an advanced microprocessor to perform continuous self-diagnostics on the electronics module and sensor elements. Using an intelligent user interface, the unit is designed to be easy to install and adjust while displaying process conditions. It can also be controlled and monitored remotely. It’s housed inside copper-free aluminum and powder coated in polyester TGIC, and has a NEMA 4X coating for additional corrosion- and weather-resistance. 403/253-7939; www.telematic.com.
