Portable Dryer Troubleshooting

Temperature Charts

We use two (2) different types of sensors (NTC thermistor on the Competitor Series 2000, and an

encapsulated sensor on the E.M.C.S dryer) in our dryers. The resistance of the sensors varies according to the

outside temperature. For example, on the E.M.C.S. dryers, for every one (1) degree rise in temperature the

resistance increases 4.8 ohms. However, on the Competitor Series 2000 dryer, the sensor reacts just the opposite,

the resistance rises with colder temperatures. The charts displayed above will help when troubleshooting any

sensor problems.
