RX-102B-CB specifications
Standard curve RX-102B-CB does not follow a standard curve
Recommended excitation1 20 µV (0.05 K to 0.1 K); 63 µV (0.1 K to 1.2 K); 10 mV or less for T > 1 K
Dissipation at recommended excitation 7.5 × 10–8 W at 4.2 K
Thermal response time 0.5 s at 4.2 K, 2.5 s at 77 K
Radiation effects Recommended — See Appendix B for more information
Magnetic field RX-102B-CB is not recommended for use in magnetic field
Reproducibility2 ±15 mK
1Recommended excitation for T < 1 K based on Lake Shore calibration procedures using an AC resistance bridge—for more information, refer to Appendix D and Appendix E
2Short-term reproducibility data is obtained by subjecting sensor to repeated thermal shocks from 305 K to 4.2 K
