Webb14 juni 2013 · Enrichments in the thermowell calculation tool include a larger variety of thermowell geometries, such as stepped thermowells, and the updated ASME PTC 19.3 TW-2010 standards have enhanced resonant frequency calculations allowing the maximum thermowell length to be determined based upon the process conditions. WebbThe PTC 19.3 critical frequency calculation [1,2] combines a single-degree-of-freedom (SDOF), discrete- ... Murdock approximation, E is the modulus of elasticity, is the unsupported length of the thermowell, L and γ is the specific weight of the material. Recasting the Murdock critical frequency estimate in the form of Eq. (4) ...

Webb3 apr. 2024 · The insertion length is the distance from the end of the well to the underside of the thread, or other connection means, (also known as U dimension). For best accuracy, this length should be long enough to permit the entire temperature sensitive part of the thermometer bulb to project into the medium being measured.
