The CS-501GR capacitance temperature sensor from Lake Shore Cryotronics, Inc. is designed for cryogenic applications, particularly in environments with strong magnetic fields. It features minimal magnetic field-induced errors, ensuring stable temperature control with fluctuations kept to a minimum during magnetic field sweeps. The sensor operates effectively within a temperature range of 1.4 K to 290 K and has a nominal capacitance of 6.1 nF with a sensitivity of 26 pF/K. Calibration is essential for accurate readings, as variations in capacitance/temperature curves can occur due to thermal cycling. It is recommended to use another temperature sensor for initial measurements in zero field conditions. The CS-501GR exhibits long-term stability with an expected drift of ±1.0 K per year and requires a stabilization period after cooling to minimize short-term drift. The sensor's physical dimensions are 3.0 mm in diameter and 8.5 mm in length, with a mass of 260 mg.
CS capacitance sensors are ideally suited for use as cryogenic temperature control sensors in strong magnetic fields because they exhibit virtually no magnetic field dependence. Displacement current is not affected by magnetic fields. Consequently, temperature control fluctuations are kept to a minimum when sweeping magnetic field or when changing field values under constant temperature operation.
