Difference between thermocouple and RTD I. Nature of the signal RTD itself is resistance, temperature changes, so that the resistance to produce positive or negative resistance changes; and thermocouple is to produce changes in the induced voltage, he changed with the temperature. Although they are contact temperature measuring instruments, but their temperature measurement range is different, the...

Thermistor Fault How can I detect it? Briefly Thermistor device fault detection: 1.First, observe the appearance of the thermistor. Potentiometer or thermistor must be clearly marked, solder pads or pins are not corroded, the rotary axis rotation is flexible, appropriate tightness, when turning the feel is smooth, while no mechanical noise and jittery phenomenon. 2.Gently shake the poten...
