Webb• Less down time - durability reduces unscheduled maintenance responding to sensor failure caused by wear. • Purchasing cost - Significantly less expensive than stellite coated thermowells. • Reduced Total Cost of Ownership - Less time spent fixing, less money to purchase and less energy to run your plant efficiently means savings to you WebbAny temperature change in the process took longer time to affect the sensor if thermowells are present; thus the response time is increased. This factor must be considered when specifying a thermowell; except when thermal equilibrium exists, a temperature measurement will probably be inaccurate to some extent.

WebbThe thermowell is a hollow metal tube with one side sealed to protect a temperature sensor from corrosive process media under high pressure and high-temperature environment. The response time of the thermowell is high because the heat to the sensor must be transferred through the thermowell.

Webb27 aug. 2013 · The speed of response of the sensor itself is virtually immediate when compared to the much slower response of the measurement system when using a thermowell. The mass of the thermowell far exceeds that of the sensor and will always be the dominant factor of measurement response. canada get first computer ibmWebbThermowells transfer heat from the process to the installed sensor but “thermal inertia” is introduced. Any temperature change in the process will take longer to affect the sensor than if the thermowell were absent; sensor response times are thus increased.
