The difference between bimetallic thermometer and common bimetallic thermometer

The bimetallic thermometer are often exposed to sunlight, the solar energy system is often used in harsh environment conditions, such as high temperature and ultraviolet (uv) radiation. In Europe, sunny days will result in the solar system in the field temperature as high as 100 ° C. At present, we can use all kinds of material with PVC, rubber, TPE and cross-linked with high quality material, but unfortunately, the rated temperature of 90 ° C rubber bimetallic thermometer, and even the temperature of 70 ° C rated PVC bimetallic thermometer is often used in outdoor, the national golden sun project horse, there are many contractors in order to save costs, not to choose bimetallic thermometer specially used for solar system, rather than the ordinary PVC bimetallic thermometer to replace the bimetallic thermometer, obviously, this will greatly affect the service life of the system. Characteristics of the bimetallic thermometer is made up of the bimetallic thermometer is special insulation and sheath material, we call it a crosslinked PE, after irradiation accelerator irradiation, the molecular structure of bimetallic thermometer changes, thus providing the aspects of performance. Mechanical load, in fact, during the period of installation and maintenance, bimetallic thermometer can wiring on the edge of the roof structure of sharp, bimetallic thermometer at the same time must be under pressure, bending, tension, cross tensile load and strong impact. If the bimetallic thermometer sheath strength is not enough, the bimetallic thermometer insulation will be seriously damaged, which affects the service life of the bimetallic thermometer, or cause a short-circuit, fires and injuries and other issues.
