Sanitary sensors intended for Clean-In-Place and Steam-In-Place service are constructed to resist thermal cycling, caustic and acid cleaning agents, and high-temperature steam sterilization to 134°C. EPDM or PTFE gaskets resist CIP chemicals. 316L SS sheath resists pitting corrosion from common CIP solutions.
