Model#: WSD-1200H

2024 Apr Update: This controller is upgraded to WSD-1200H

The WSD-1200H is a dual-probe plug-and-play PID temperature controller for controlling the temperature of the Bradley Smoker and other electric smokers. The original temperature control mechanism of the Bradley Smoker is unstable and inaccurate. For the same dial position, the smoking temperature can vary significantly depending on content in the smoker, ambient temperature, wind speed, ambient humidity, and even the direction of sunshine. Utilizing a special PID algorithm, this controller is able to automatically adjust power to the heater in order to compensate for these disturbances and maintain the smoking temperature to within one degree precision.

This controller has two sensor probes, 6 programmable steps, and an AC output that is synchronized with program step(s). Users can use the first probe to control the temperature of the smoker cabinet. The second pointed probe is used to be inserted into food so that the internal temperature can be monitored. The ending criteria of each step can be determined either by the preset time or the preset internal food temperature. For cooking small-sized food or smoking the surface of food, users can use the preset time as a reference point to finish the step. Using the internal temperature as the reference point is important for cooking larger sized food, because it is difficult to know how much time is needed to cook this large sized food. For example: You can program the temperature to start at 120 °F for 1.5 hour of smoking, increase to 132 °F for 2.5 hours and finish at 190 °F until the internal temperature reaches 170 °F. Then, the controller can either turn on a buzzer to let you know the food is ready, or drop the temperature to a lower set point to keep the food warm until you are ready to serve it. This will save you time waiting by the smoker to change the settings manually when each step is finished. The synchronized AC output can be used to turn on and off the smoker generator with the program step(s). For example, you can program the smoker to dry the sausage at 140F until the internal temperature reaches 100F (step 1), turn on the Bradley Smoker generator for 2 hours at 150 °F (step 2), then, turn off the generator to continue the next step. (This function might not be used for Bradley Digital Smoker because it has a built-in timer).  Up to two program steps can by synchronized with the AC output.

Note

1) For Bradley Digital Smoker owners, an extra power cord is needed . You can use a regular computer power cord of your own.

2) For international order, a US power cord is included (hardwired to the back of the controller). Users can splice the connector off the cord to a power strip outlet that meets the local standards for the output.  For the input, the controller has standard IEC 320 C13/14 socket. Users can use a computer power cord that meets the local standard to power it.

3) The power rating is 1440 watts for 120VAC, more than sufficient for the 500 watts required by the Bradley smoker. It will also work for Bradley Smoker that has an additional 500 watts heater installed. If you are going to use it for larger smokers, you need make sure the total power drawn, including the smoker generator control output, should not exceed 1440 Watt at 120V (or 2000 Watts at 240V).
