Features: Brand new and high quality Dumas wire has the same expansion coefficient as packaging glass, and the diffusion of cuprous oxide in glass during sealing is beneficial to improve the sealing strength with glass. In the case of more reliable use, it has more accurate temperature measurement performances. The cable is flexible, not easy to be broken, fast in thermal induction and sensitive in response, and can be used in harsh environments such as high temperature. Thermistor sensor with glass package, the radial cable is packaged with Dumex glass, which has high temperature resistance, can provide a wide working ranges of -30 to 300℃ and has high reliability. Widely used in 3D printers and high-temperature product.
