Temperature sensor is a sensor that senses temperature and converts it into a usable output signal. It is the core part of the temperature measuring instrument. According to the measurement method, there are two types of temperature sensor: contact sensor and non-contact sensor. And according to the characteristics of sensor materials and electronic components, it falls into two categories: thermal resistance and thermocouple. ATO offers you different kinds of thermocouples and RTD sensors. When you need to buy a temperature sensor, we'll cover every detail to help you make the most economical and practical decision.
