Temperature is a core physical parameter in industrial production, and its measurement accuracy and level of intelligence are directly related to production efficiency, quality, and safety. Siemens relies on its profound technological accumulation to create a full range of temperature sensor matrices. Through sensing innovation and intelligent interconnection technology, it breaks the limitations of traditional temperature measurement, provides full scenario solutions for multiple industries, and reconstructs a new paradigm for industrial temperature measurement.
Core sensing principle: Building a solid foundation for precise temperature measurement
The core of Siemens temperature sensors relies on thermistor and thermocouple technology to build a wide temperature range and high-precision temperature measurement foundation.
