Fig 5. Sensor position. Left, the sensor should be placed close to the food but high
enough so that it does not touch the food. Right, hold the sensor in place with a piece of
tape.
For the
“Original” and Stainless Steel Bradley smoker, the Temperature Heat Control
Switch on the smoker tower should be slid to the Hi position (Most right).
For the Bradley Digital Smoker, the original sensor cable from the smoker should be
connected between the generator and smoker.
The controller is ready to power up.
2) Important consideration for better control results.
The following is a list of things that could affect the result of temperature control.
a) The smoker and controller location. The smoker should not be placed directly under
the sun. Direct sun light can heat the smoker to above 140 °F in the summer time,
making controlling the temperature at 140 °F impossible. This is especially the problem
for the Bradley Original Smoker because of its black color. The controller should be
placed away from direct sun light also. Although the controller uses a high intensity LED
display, it will still be difficult to read when sun light is directly shined on its surface. Users
should also avoid exposing the controller to water and rain, which could damage the
controller.
b) Low temperature control. The control result for temperature below 125 °F will not be
as good as higher temperatures when the smoker generator is on. This is because there
are two heaters in the smoker tower. One is the smoker heater controlled by PID
controller. The other is the heater from generator that is not controlled. Our test shows
that the heater in the generator itself can raise the temperature of the smoker tower by
60 °F (2 hours, in the shade with the damper open). That means when the ambient
temperature is at 70 °F, the smoker can be heat up to 130 F in 2 hours by the heater of
the generator (without using the heater of the smoker).
