Lake Shore Temperature Sensors, Other

Thermocouples
Thermocouple wire is 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 thermocouple wire in use. 

Capacitance
Capacitance sensors are ideally suited for use as temperature control sensors in strong magnetic fields because they exhibit virtually no magnetic field dependence. Small variations in the capacitance/temperature curves occur upon thermal cycling. It is recommended that temperature in zero field be measured with another temperature sensor, and that the capacitance sensor be employed as a control element only.
