I am using Omega X Series Multi Channel Thermocouple Loggers to get data from K-type grounded thermocouples. However, since my computer is connected to the wall, which is also grounded, I cannot get measurements. I was wondering if there was anything I could use such as isolation transformers to be able to disconnect the two grounds and get real time measurement.
It’s conceivable however that the reader itself may have some objection to the thermocouples’ sharing a common connection, in which case the ground isolation may not help a whole lot. That might be a possibility worth checking before spending money on an isolation solution.
