Hi everyone. I was wondering if anyone could help me with the following questions regarding pad type tube skin TCs:
- If I'm not mistaken, the material of pad and MI cable sheath for tube skin thermocouples must be the same, otherwise the couple might introduce an unwanted voltage in the readings. So, are ss310 and ss316 considered same or different materials in this regard?
- Can the TC junction be either grounded and ungrounded in this type? Where exactly should you place the grounded junction? (on the MI cable wall close to pipe wall, or on the end cap)
- Is there a standard, reference or guide for manufacturing different types of thermocouple sensors? (One that could answer questions such as those above, includes info on welding procedure, etc.)
Thanks.
