Expansion thermometers operate by utilizing the volume changes of an expansion medium (such as liquid or gas) with temperature variations. These changes are converted into readable temperature values through an internal mechanism, displayed via a pointer or digital device. Made from durable materials, they are suitable for high-temperature and high-pressure environments, such as chemical, petroleum, and food processing industries. With simple structures and accurate measurements, they effectively handle corrosion and extreme conditions. Various connection options and adaptable designs are available—please share your requirements for tailored recommendations.
