RTD Error

Has anyone ever experience a really slow RTD response or where an RTD would be way out of range? I had an instance in a Master/Slave loop where the Master, using a RTD, had a value way different from the inner loop. I believe the temperature to be off, but testing proved otherwise. Anytime I've had a RTD fail it's always just opened up.

Thanks
 
Open failure of of wire RTDs are the most likely, but they can fail in several ways that your maintenance testing can sort out. Be aware that many modern RTDs are so-called thin-film versions with other failure modes.
