Heraeus C Series – Cryogenic Elements

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.  Pt100 and Pt1000 sensor elements are both available.

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