Explain the working principle of temperature measuring cable

The temperature measuring cable is mainly divided into two types: analog temperature measuring cable and digital temperature measuring cable. The temperature measuring cable must contain at least one temperature sensor, and multiple temperature measuring cables can be set as needed. The general temperature measuring cable is composed of a temperature sensor, a conductor, a tensile steel wire rope and a sheath. A digital temperature measuring cable refers to a temperature measuring cable in which the sensor contained is a sensor chip, which outputs a digital signal and has two or three inner cores.
