RTDs available today can generally be categorized into one of two basic types, depending on how their temperature sensing element is constructed. One type of RTD contains wire-wound elements and the other type of RTD contains thin-film elements. Each type is best suited for use in certain environments and applications.

Which one performs better, a wire-wound or thin-film resistance temperature detector (RTD)? The answer depends on several variables, especially your process environment. Adding to the confusion are different standards, IEC and ASTM.

2021年4月26日 · TE’s platinum thin-film elements offer a broad temperature range from -200°C to +600°C with low drift and fast response time. The compact design of the platinum elements allows for easy packaging in custom probes and assemblies.

Wire wound RTD is costlier as compared to thin-film RTD. The thin-film RTD elements are made by depositing a very thin layer of metal (usually platinum) onto a ceramic substrate material. The metal film is cut by the laser or etched into an electrical circuit pattern which provides it the specified amount of resistance.

2024年1月19日 · Thin Film RTDs. These RTDs consist of a platinum-based thin film, often only a few micrometers thick, deposited onto a ceramic substrate through advanced physical vapor deposition techniques. This film is then laser-etched to create an accurate electrical circuit pattern, ensuring consistent resistance characteristics.

Littelfuse thin film platinum RTDs (Pt-RTD) consist of a passivated thin film platinum element deposited on a ceramic substrate. Thin film Pt-RTDs provide cost advantages when compared to wirewound platinum resistance temperature detectors. Glass coated platinum element. Virtually linear relationship between temperature and resistance.

2024年12月23日 · RTD types (RTDs) are versatile temperature sensors that can meet the needs of different application scenarios depending on material properties, resistance temperature coefficient and resistivity. Platinum RTDs are suitable for high accuracy and wide temperature range applications, nickel RTDs are a cost-sensitive temperature measurement ...

The 650 series thin film element RTD sensor is composed of platinum deposited on a ceramic substrate, then coated with glass. The thin film element can be integrated in different designs of probes.

Thin-film RTDs: feature a thin layer of platinum deposited on a substrate, making them more robust and cost-effective. Fluke offers a thin film designed probe in our 1551A thermometer. ... RTD: Measures temperatures from -200 °C to 660 °C, making it suitable for moderate ranges. Thermocouple: Can measure from -270 °C to 2,300 °C, ...

2024年3月12日 · RTD stands for Resistance Temperature Detector and Pt100 stands for Platinum 100. Platinum is the most noble material in the world. ... Additional to the standard thin-film and wire-wound sensors which are very common in the industry, Endress+Hauser has developed innovative sensor technologies like the StrongSens, the QuickSens and the self ...
