Resistance Temperature Detectors, abbreviated RTDs, are wire and thin film devices widely used to measure temperature in laboratory and industrial processes. Equipment made of a thin layer of metal on a ceramic substrate is reliable and can provide a higher level of accuracy compared to other temperature measuring instruments such as thermocouples or thermistors. However, in order to withstand high temperatures while maintaining excellent stability, RTD temperature sensors must be made of special materials. Therefore, RTDs are usually made of copper, nickel and platinum to meet the growing demand for accurate temperature sensing. Among these metals, platinum is particularly preferred for most industrial applications where accuracy and durability are paramount. What is the reason for the growing popularity of platinum resistance temperature detectors? This post briefly describes the same.

Pt100s and Pt1000s are the leading types of platinum resistance thermometers available today for critical temperature sensing applications. As simply defined, Pt100 is 100 Ω at 0 ° C and Pt1000 is 1000 Ω at ⁰C, although there is the same operating temperature and response time range. RTD Pt100 and Pt1000 also have the same sequence of tolerances and temperature coefficients of resistance. Their high resistivity and non-degradable electrical resistance over time make them suitable for a wide range of processes and tools. The Pt100 sensor is available in both thin film and coiled wire and is compatible with most industrial instruments and processes. On the other hand, the Pt1000 is offered in 2-wire configurations, making it suitable for battery-powered applications. Regardless of their differences, both Pt100 and Pt1000 offer good consistency, high accuracy, long life and more.

Platinum RTDs offer unrivaled and reliable performance in harsh and harsh conditions and have built a reputation for accuracy, repeatability and robustness. The platinum temperature resistance detector offers unsurpassed performance over a wide temperature range. They show limited susceptibility to contamination, impressive chemical strength, strong electrical properties and high resistance to wear and damage. Below are the most important factors that prove the use of platinum in the production of RTDs.

Easy to shape and process: Platinum, a highly prized and desirable metal, is extremely soft and fast. This metal property accelerates the machine and expands to the required shape according to RTD technical specifications without affecting the dimensional strength.

Inactive: This heavy, rare, silvery white metal is described as a noble metal for its inactive character. It is resistant to most natural elements and does not react with air, water, heat or most chemicals and common acids.

Strength: Platinum is one of the strongest elements and is not affected by external loads, mechanical vibrations and vibrations. This feature is one of the other advantages because RTD temperature sensors are constantly exposed to such harsh conditions during industrial operations.

High temperature resistance: Platinum resistance temperature detectors always operate over a wide temperature range. It offers a higher level of accuracy even when exposed to a temperature range of -200 ° C to 600 ° C. The question "why platinum is used in RTD temperature sensors" is well illustrated in the discussion above.
