1. Product features and uses: This product is specially designed for the development of underground hot water resource management. The integrated transmitter works together with the water pump in deep wells, making replacement and inspection extremely difficult. Therefore, special working conditions such as high durability, high temperature water resistance, aging and corrosion effects of high-temperature mineral water are considered in the material selection design, and the special working location is taken into account. Safety lightning protection design is added and user requirements are taken into account. It is designed as a water temperature composite sensor. When the water temperature is not higher than 110 ℃, the integrated design is adopted. When the water temperature is 110-130 ℃, the sensor is separated in the water and the transmitter outlet is in the wellbore air. The cable adopts the principle of using No. 4 or No. 5 high-temperature cable and No. 6 tensile cable in combination. The plan and length are selected by the user through ordering.
