Hi all,

You maybe have a solution for a problem of mine with regard to temperature measurement with thermocouples or at least may have a reason of this occurance.

After several full weeks of working of the system, spesificaly front-end chip(s) of the thermocouple interface section blew up very badly, even the housing of the chip(s) was badly destroyed. This situation repeated a few times. I, first checked if mains leakage exist but found none. May this be happen just because of transients? or because of static electric discharges that may happen momentarly.

Sorry if this found off-topic.
