The Sentinel is available as an option on any Paragon kiln that comes with the 12-key Sentry controller.
The new controller is made by Bartlett Instruments of Fort Madison, Iowa. New Paragon kilns equipped with the Sentinel give a continuous amperage and circuit voltage readout during firings. This is to inform the kiln user of voltage drops during times of heavy electrical demand, such as hot summers. The amperage reading indicates when the elements are beginning to wear.
Ramp-Hold programs can have a customized program title, which is entered through a touch screen. Store 12 custom programs with up to 32 segments per program. The Sentinel includes Novice Mode, which adds questions to guide you during programming. The controller can be updated through WiFi. View the progress of a firing in graph mode. The firing schedule can be edited during firing with Skip Step, Add Segments, Add Temperature, and Add Time. The Sentinel can turn a kiln vent or gas injection flow meter on or off for each segment of a program.
You can download the Bartlett KilnAid app, and monitor your firings through your smartphone.
