J Type Thermocouple Sensor, Temperature Range: 0 to 750 deg C, 150 mm

A Thermocouple is a sensor used to measure temperature. Thermocouples consist of two wire legs made from dissimilar metals. The wire's legs are fused and welded together at one end, creating a junction. This junction is placed where the temperature is to be measured. When the junction experiences a change in temperature, a millivoltage is created. The voltage can then be interpreted using thermocouple reference tables to calculate the temperature. the thermocouple is often enclosed in a protective sheath to isolate it from the local atmosphere. This protective sheath drastically reduces the effects of corrosion. Thermocouples are typically selected because of their low cost, high-temperature limits, wide temperature ranges, and durable nature. Alloy Combination: Iron/Constantan Temp. Range: (0 to 760) °C [32 to 1400] °F The type J thermocouple is suitable for vacuum, reducing, or inert atmospheres, oxidizing atmosphere with reduced life. Iron oxidizes rapidly above 538 °C [1000 °F], so only heavy gauge wire is recommended for high temperature applications. Bare elements should not be exposed to sulphurous atmospheres above 538 °C [1000 °F].
