The ETT-10V consists of a magnetic, high tensile strength, stretched wire fixed to a material with different coefficients of linear expansion. Any change in temperature directly affects the tension in the wire, and thus, its natural frequency of vibration. This temperature sensor is specially designed for measurement of internal temperature in concrete structures, soil or water. It is made of stainless steel and is hermetically sealed under a vacuum of 0.001 Torr.
