Semiconductor temperature sensor is integrated circuits ( IC) Structure, basic design principle based on the semiconductor diode volt-ampere characteristics and the relationship between temperature, has the characteristics of small package, high precision and low price, and easy to connect to other devices. 1, the simulation of the temperature sensor in the early IC temperature sensor provides a proportional to the temperature of the output voltage or current. We improved the thermistor of existing products, the characteristics of the resistance changing with temperature is nonlinear relationship. Now the analog temperature sensor without additional linear circuit to calibrate nonlinear thermal resistor. 2, digital temperature sensor output in many applications, * will need to provide the temperature data in digital form. This can be achieved by a simulation of the temperature sensor output from an AD converter ( ADC) To implement. However, with the progress of IC manufacturing technology, this kind of ADC and many other functions are integrated into the temperature sensor on the tube core has become the economic and effective method. It can reduce cost, printed circuit board ( PCB) Area and power consumption, simplify system design engineer tasks at the same time. Through the above content, we understand the types of IC temperature sensor includes analog temperature sensor and digital temperature sensor. But each type includes many kinds of products. Analog temperature sensor generates a voltage or current signal proportional to the temperature. Digital temperature sensor to monitor local and remote temperature, and also includes many other features. In addition to the above products, the company also supply pt100, pt100 temperature sensor, temperature transmitter, and other products, our company have a practical technology, professional operation team, to create on the premise that the user experience for your service, the service of the supreme good to beauty is our endless pursuit. Because of the people-based, so trustworthy; Because professional full-time, so worthy of choice. The above information is for reference only. For details, please contact related staff to answer you.
Nowadays, the adoption of temperature sensor in custom thermistor industry is quite common.
