The digital temperature cable converts the temperature signal into a digital signal through the internal digital signal processor, thereby achieving high-precision, real-time temperature monitoring and control. The principle of measuring temperature is mainly based on the thermoelectric effect, that is, using temperature measuring elements such as thermocouples to generate thermoelectric potential when the temperature changes, and then converting it into a digital signal for output through a digital signal processor.

Structure
Digital temperature cable is generally composed of multiple components, including sensor element, wire, insulation material and outer sheath. The sensor element is usually a temperature-sensitive material, such as a thermistor, thermocouple, etc. The wire is used to transmit electrical signals, the insulation material is used to isolate the wire and the sensor element, and the outer sheath is used to protect the cable from damage by the external environment.
Features
Accurate temperature measurement
The digital temperature cable uses the DS18B20 chip imported from the United States, which can monitor the temperature changes at various locations along the cable wiring in real time. It has high accuracy and the maximum deviation of the temperature sensor is ±0.5°C. It can accurately measure the temperature of grains to enhance real-time temperature monitoring and will not drift over time.
Distributed measurement
Unlike traditional grain measuring equipment, the temperature cable can perform continuous and distributed temperature monitoring along the entire length of the cable, which can detect local temperature anomalies earlier and prevent safety hazards.
Environmental corrosion resistance
The temperature cable is made of food-grade, corrosion-resistant high-molecular polyethylene material, suitable for working in grain storage environments, and is resistant to moisture and corrosive gases.
