tk8000-ex thermocouple isolated barrier
http://www.ahdqjt.com time: 11/26/10 15:48general description
tk8000-ex thermocouple isolated barrier or temperature transmitter, converts thermoelectric power from the thermocouple to 4 ~ 20madc (or 1 ~ 5v dc) output, which has a linear relationship with temperature. so it has automatic cold junction compensation function.
