Type E thermocouple wire from Lake Shore Cryotronics, Inc. is designed for low-temperature applications, exhibiting the highest sensitivity among standard thermocouple types, making it suitable for temperatures as low as 40 K. The wire is available in two gauges: 30 AWG and 36 AWG, both featuring Teflon insulation with a wall thickness of 76.2 µm. The operational temperature range extends from a minimum of 3.15 K to a maximum of 953 K, although the upper limit may depend on wire size and insulation removal for higher temperatures. This thermocouple wire is particularly useful in cryogenic environments, where special techniques are necessary to achieve accurate temperature readings.
Thermocouples are used in a variety of cryogenic applications, but special techniques must be employed to approach temperature accuracies of 1% of temperature, even without consideration for the effects of high magnetic fields or high radiation fluxes. The problems are further complicated by exposure to variable gradient conditions at cryogenic temperatures.
Many Lake Shore temperature controllers offer inputs that accommodate most common types of cryogenic thermocouples in use.
Has the highest sensitivity among the three standard thermocouple types typically used at low temperatures (types E, K, and T). The best choice for temperatures down to 40 K.
Recommended for continuous use in inert atmospheres. Has a sensitivity of 4.1 mV/K at 20 K (about ½ of Type E).
