C – Cryogenic

Heraeus C series thin-film PRTDs are suitable for use down to -196°C and combine the ideal curve characteristics of ceramic wire-wounds with the vibration resistance of glass wire-wound RTDs.

They are therefore useful for some cryogenic applications and are characterized by their high long-term stability, excellent temperature shock resistance and a wide temperature range of -196°C to +500°C.
