K Type Silicon Carbide Thermocouple
The K Type Silicon Thermocouple provides the widest operating temperature range of any thermocouple type due to the use of traditional base metals. The positive leg of the thermocouple is made from a non-magnetic metal, while the negative leg is made from a magnetic metal, usually nickel. This allows the thermocouple to work at high temperatures and provides the widest operating temperature range.
The defining quality of K Type Silicon Thermocouple is that the output is distorted when magnetic material reaches its Curie Point, which is around 185 °C. K Type thermocouples work most effectively in oxidizing atmosphere at temperatures up to 1260°C (2300°F) and the tolerance class is ± 1.5 K between -40 and 375 °C.
Key Features:
- Mostly used at temperatures above 540 degrees C
- Small in size and reliable
- Faster response
- Less expensive.
- Type K Thermocouples have a longer life than Type J.
