  • Page 23: Temperature Control Conversion Chart

    17. TEMPERATURE CONTROL CONVERSION CHART 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.
