Type E, NiCr-CuNi thermocouple is a high-accuracy thermocouple for a moderate temperature range. In general, it has a smaller temperature range compared to other thermocouple junctions: -270°C to +900°C. Type E thermocouples are distinguished for their high Electromotive Force (EMF) output per degree, making them the most efficient among all standard thermocouples for applications that demand high EMF output.
They exhibit excellent resistance to oxidation within an operating temperature range of 150°C to 870°C, making them ideal for use in thermal-generators or thermopiles, where they accurately measure very small temperature differences.
These thermocouples are well-suited for cryogenic applications due to their high output of 68μV/°C and are non-magnetic. They provide a broad operational temperature range from -50°C to +740°C and a narrower range from -110°C to +140°C.
