Platinum Resistance Temperature Detector

Cyntec's platinum resistance temperature detector (Pt-RTD) chip consists of thin-film platinum deposited on a high-purity aluminum oxide substrate. In a chip form, the Pt-RTD provides a significant cost advantage compared to the conventional wirewound Pt-RTD.

Due to the stability of the TCR of the platinum element, OTP protection function, the highly advanced packaging materials, and processing technologies, the Pt-RTD in a chip form can withstand temperatures ranging from -260°C to +1000°C.

The main feature of Pt-RTD is the linear relationship between temperature and resistance value, which is a key characteristic needed to be able to measure temperature over a very wide range of operating temperatures. Pt-RTD will maintain a significant rate of resistance range vs. temperature change in the high range of the operating temperature which is ideal for digital control, unlike PTC and NTC which do not provide such performance at high temperatures.
