Sensor Selection - Lakeshore 335 User Manual

1.2 Sensor
Selection
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 0.3 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
curveabove 70 K and are interchangeable in many applications.
