This kiln can be ordered with the optional Sentry 12-key controller instead of the standard Sentry Xpress 3-key controller. The upgrade price is only for a Sentry 12-key ordered with a new kiln.
Because you can type numbers into the 12-key Sentry, it is faster to program than the 3-key. (Numbers are programmed into the 3-key Sentry Xpress by scrolling up or down with arrow keys.)
Ramp-Hold programs are divided into segments. Each segment has a target temperature, firing rate, and, if desired, a temperature hold. Hold (soak) maintains a specific temperature. (Programs remain in storage even when the kiln is unplugged.)
Program Storage, 12-key Sentry: one 20-segment and eight 10-segment programs
Program Storage, 3-key Sentry Xpress: four custom programs, 8 segments (steps) each
General Features That are Unique to the 12-key Sentry
Firing Cost: Enter your cost of electricity and the kilowatts used by your kiln. At the end of a firing, the controller will give the cost of electricity to fire that load. Find out how little a kiln actually costs to fire. Learn to conserve energy by experimenting with firing speed, load density, etc.
AOP Vent: The “Auxiliary Output” is available on most Paragon kilns that have the 12-key Sentry. The AOP is a relay-powered electrical receptacle mounted to the kiln. You can plug an Orton Vent Master into the AOP to control when the vent operates during firing.
Stop/Back Key goes back one step with each key press during programming to correct errors.
Add Time Key adds five minutes to a temperature hold with each key press during firing. Helpful for glass with holds.
Thermocouple Selection: The 12-key Sentry can operate types K, S or R thermocouples.
Program Safety Lock for the program in active memory gives you peace of mind.
