Vibrating Wire Temperature Sensor

ETT-10V temperature sensor is designed for measurement of internal temperature in concrete structures, soil or water. It consists of a magnetic, high tensile strength stretched wire fixed to a material with different co-efficient of linear expansion. Any change in temperature directly affects the tension in the wire and thus its natural frequency of vibration.
