Proper placement of capacitors in the layout is crucial to minimizing EMI. When used properly, capacitors create a high-frequency ground to from a lowpass filter, bypassing the RF signal to ground. Capacitors also have a self-resonant frequency, a point at which it becomes inductive. Just like an inductor, a capacitor should be used below its …

Thermocouples generally have a rating of a temperature range, and this information is usually pretty easy to find either on the datasheet or on the thermocouple''s product page. Thermocouples with a higher temperature rating are typically made of a high concentration of rhodium, making type S, R, or B thermocouples significantly more costly.
Thermocouples are the temperature sensing probes that protrude into your kiln chamber and feed information to your controller. Just like elements they can degrade over time. Again, it depends on the temperatures you are firing too and the amount of combustibles they are exposed to that determines how long they will last.
Calculations for this design are shown for a single K-type thermocouple with a temperature measurement range from –270°C to 1370°C. This circuit can be used in applications such …
