WZPKK Series Armored Assembly Platinum Resistor

The assembled platinum resistor is a structural product inherited from the method of temperature measurement using platinum resistor established 200 years ago. It is still widely used in modern industrial temperature measurement. In the past, due to less advanced manufacturing techniques for platinum resistance elements (e.g., mica resistors), large-diameter protective tubes of φ16 or φ12 had to be used. Its advantages include wide market availability and strong adaptability. However, it has drawbacks such as slow response speed, material wastage, and incompatibility with most compactly designed instruments, limiting its use to engineering applications. This series of platinum resistor employs high-reliability platinum resistance elements, enhancing stability. It also addresses issues faced by similar products from other manufacturers, such as the damage caused to elements in high-temperature and vibrating environments due to the weight of ceramic beads used for lead wire threading.
