RTD Temperature Sensor

RTD (Resistance Temperature Detector) sensors represent the pinnacle of precision temperature measurement technology, utilizing the predictable and linear relationship between platinum resistance and temperature to deliver unmatched accuracy and stability across extreme temperature ranges from –200°C to 850°C. These sophisticated temperature sensors are manufactured using high-purity platinum wire wound on ceramic substrates or thin-film deposition techniques, ensuring exceptional repeatability, long-term stability, and minimal drift characteristics essential for critical industrial and laboratory applications.

Ultra-fast response times with thin-walled sheaths (0.5-5 seconds)
Superior accuracy ±0.1°C (Class A) with long-term stability
Rugged, corrosion-resistant construction for harsh environments
