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.
Greetings,
We do have a variety of plug-in isolation transformers in stock that could be used to interrupt ground loops arising from the USB-chassis connection. USB isolators are also a thing.
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.
