+ Internal amplifier Thermocouple TC0V Thermocouple Fig. 19: Floating thermocouple connections If, however, the thermocouple is connected to an object which is grounded, then the connection shown in Fig. 20 should be used. Here, a connection is made between “0V” on the controller and a location near where the thermocouple junction is attached to the remote object under measurement. This equalizes the grounds of both the temperature controller and the object. + Internal amplifier TC- Thermocouple Remote object under measurement N/C 0V Thermocouple Ground reference Fig. 20: Remote grounded thermocouple connections 21 Remote object under measurement
