The Glass Wire Wound temperature sensors have the same manufacturing concept as the CWW Ceramic Wire Wound sensors. 

This concept ensures excellent resistance to vibration and mechanical shock. Another interesting feature of the GWW airtight construction is its resistance to humidity and direct exposure to acidic or alkaline liquid media.


Glass sensors are available in single or dual version and its typical operating temperature ranges varies from -200 to +400 ° C depending on the model.
