pt100 is a platinum thermal resistance, its resistance value will change with the change of temperature, common pt100 temperature sensing elements have ceramic elements, glass elements, mica elements, they are made of platinum wire around the ceramic skeleton, glass skeleton, mica skeleton and then through a complex process. Widely used in medical, motor, industry, temperature calculation, resistance calculation and other high precision temperature equipment.

According to the requirements of the specific circuit board, the sampling resistance is divided into plug-in resistance and patch resistance. Sampling resistance, low resistance, high precision, resistance precision within ±1%, more demanding uses will use 0.01% precision resistance. Most of them are plug-in resistors made of Constantan and manganese copper.
The twisted wire is realized by rotating the twisted single wire around the twisted wire axis and moving the twisted wire forward at uniform speed. Commonly used are pure nickel, Constantan, nickel chromium and other twisted into a variety of different specifications of cross sections and different types of cores. It is suitable for the occasions where the working frequency is high and the skin effect and proximity effect loss of single strand wire are too large. The use of stranded wire can reduce the operating temperature, compared with the same cross-sectional area of single strand wire, stranded wire has higher mechanical, flexibility.
The main materials of the ring are nickel chromium and iron chromium, we can customize according to the needs of users, and provide the necessary accessories for many products, such as mica tape, mica sheet and so on.
