What are the core competitiveness of these temperature transmitter? This component_ Temperature transmitter is an important measurement sensor/transmitter that is related to temperature. It is a device that can sense temperature and convert it into a usable signal. It is a digital electronic product that belongs to the category of analog direct current. With the pie chart above, there is an increasingly rigorous discussion on the temperature and strain measurement scheme of thermocouples.
The working principle of a thermistor is to insert two measuring terminals into a junction box. When several substances based on the thermoelectric effect are used as insulation, the corresponding temperature change occurs. The temperature change detected by the strain gauge is processed by a digital circuit to output the temperature change, thus achieving accurate measurement.
Thermocouple temperature sensor are generally specialized temperature sensor for low-cost applications, with a main accuracy of around 01 ° C, resulting in higher accuracy and reliability. They are suitable for manufacturer supply. The temperature sensor with high accuracy is not allowed to exceed 15 ° C, a trace amount will be better, the room temperature will be higher, and the voltage also needs to be lower.
Yes. The accuracy of the thermocouple is 02 ° C, and the measurement range is -150 ° C. Platinum thermistors are mainly used to measure temperature changes within the range of -200~800 ° C. Most temperature instruments and low-temperature temperature sensor use platinum thermistors, but their accuracy is almost related to humidity.
