| Sensor Selection |
| |
| Sensor Temperature Range (sensors sold separately) |
| |
| Silicon diodes are the best choice for general cryogenic use from 1.4 K to above room temperature. Diodes are economical to use because they follow a standard curve and are interchangeable in many applications. They are not suitable for use in ionizing radiation or magnetic fields. |
| |
| Cernox™ thin-film RTDs offer high sensitivity and low magnetic field-induced errors over the 2 K to 420 K temperature range. Cernox sensors require calibration. |
| |
Platinum RTDs offer high uniform sensitivity from 30 K to over 800 K. With excellent reproducibility, they are useful as thermometry standards. They follow a standard curve above 70 K and are interchangeable in many applications. |

1 Single excitation current may limit the low temperature range of NTC resistors
2 Non-HT version maximum temperature: 325 K
3 Low temperature limited by input resistance range
4 Low temperature specified with self-heating error: ≤ 5 mK
5 Low temperature specified with self-heating error: ≤ 12 mK
