"The helical strake thermowell referred to by Blake is one alternative for use in applications where a more traditional thermowell cannot be made to work. Velocity collars have been historically used as one means of changing the attributes of a thermowell to produce a suitable design for a given application. As mentioned in the original post, velocity collars have been recognized to be unreliable over the long term so are not recommended in the ASME PTC 19.3 TW – 2010 standard. There are other ways to change a thermowell design to ensure reliable service, and a helical strake thermowell design could be one solution to consider."

"Hi Kiruthika, Thanks for your comment. What technology are you using for the MPC? I can ask around if you're are using DeltaV Predict or PredictPro to see what we might have."

"Hi Steven, Thanks for your question! The wireless controllers are battery powered or can be externally powered (where wiring may already exist.) Here's the data sheet http://www.documentation.emers..."

"Thanks for your comment Mohsin. From my understanding checking with a colleague, there is a separate 800M controller for SIL-rated applications. If one is willing to use a SIL-certified platform to run BPCS logic, this should be an option, but its important to remember that to fulfill the standards, one still needs to have separate application, which will save some spare parts spending, but project implementation tends to be much higher."

"Hi Manj, Thanks for your comment! I wasn't sure so I posted your question in the Safety Instrumented Systems group of our Emerson Exchange 365 community at: http://community.emerson.com/p... You can join the community and that group to be notified of any responses. I wish you success on getting the CFSP certification!"
