20. TEMPERATURE CONTROL CONVERSION CHART - OHMS TO DEGREES
The temperature sensor (probe) that is supplied with this conveyor oven is an RTD type, which yields an
output based on Ohms of resistance. This particular RTD device has a linear resistance curve that
produces a very predictable amount of resistance that can be converted to degrees Fahrenheit. This
particular device produces a resistance increase of 2 Ohms per every 1 degree F. The baseline value is
approx. 1000 ohms at 32 °F (0°C).
