WebWhat is a type K Thermocouple? A Type K thermocouple refers to any temperature sensor containing Chromel and Alumel conductors, that meets the output requirements as stated in ANSI/ASTM E230 or IEC 60584 for Type K thermocouples. This may be an immersion sensor, a surface sensor, wire or another style of sensor or cable. WebTo determine whether the sensor is a thermistor or RTD, as well as the type, you must measure the resistance between the two different-coloured wires: An RTD PT100 will have a resistance of 100 ohms at 0 °C. An RTD PT1000 will have a resistance of 1,000 ohms at 0 °C. If the probe has a much higher resistance value, then it must be a thermistor.
