An asterisk (*) and question mark (?) This effect can be used to protect circuits or devices against overcurrents. In some applications where the heater is used only in a narrow temperature range, a simple linear equation may be adequate. The function of the PTC is very similar to that described in the previous section. Thermistors (a word combining thermal and resistor) are negative coefficient resistors that measure and control specific temperatures. Such a heating element will warm up quickly, because it produces more heat at low temperatures. NTC sensor The fin draws heat away from the ceramic element, transferring it directly to a surface to be heated. If being able to adjust the temperature is more important than holding a fixed temperature, then a PTC material whose resistance changes smoothly with temperature can be used. Visit our Application Story Library to browse other stories Voted #1 mid-sized employer in Atlanta The PTC surface heater also uses an extruded fin-like component. The resistance of the PTC then increases substantially, which in turn reduces the high current to levels that do not overstress the system.
