Thermowells are provided to protect the basic sensor from mechanical damage and corrosion. An extremely sturdy design may increase the life of the sensor but may lead to a poor response. Similarly, a delicate design will have poor life but will improve the response time. Therefore, a proper balance needs to be struck.For given process parameters, General can arrive at an optimum Thermowell design considering aspects such as temperature, pressure, fluid velocity and corrosion. Such designs will conform to ASTM PTC 19.3.The Thermowell material can be brass, SS304, SS316, SS316L, SS310, Inconel 600, Incoloy 800, Monel, Hastelloy depending upon the process parameters and type of fluid. For proper selection of Thermowell material, expert advice is available from our design department.
