The Cernox 1050 resistance sensor is the standard sensor for use in magnetic fields up to and in excess of 20 Tesla as it has a very small magnetic field dependence. Available in two packages: canister package or hermetic The canister package is somewhat more robust and is convenient for insertion in a hole. It has four colour-coded leads, 15 cm long. The hermetic package is advisable in situations where reduced size or a fast thermal response time is necessary. It is slightly magnetic and may have an effect on some very sensitive magnetic measurements, but since the total mass of ferromagnetic material is only a small fraction of the total sensor mass (itself only 40 mg), the effect will be negligible in most cases.
Calibration if purchased, includes:
- Certificate of calibration. This states that the calibration conforms to the International Temperature Scale (1990), and is traceable to NIST
- Measured calibration data
- A fit to the data based on Chebychev polynomials, with deviations
- An interpolation table
- With full calibration, sensor operates to 420o K
- All supplied on CD
