Answer / saber
If both wires of thermocouple are shorted then the output of
thermocouple will be 0 mv. The question is quite confusing.
On the other hand both wires of thermocouple reader are
shorted or connected in a shorted circuit thermocouple then
it will show ambient temp.

Answer / akhilantivirus
Detecting open thermocouples easily and quickly is especially critical in systems with numerous channels. Thermocouples tend to break or increase in resistance when exposed to vibration, poor handling, and long service time. A simple open thermocouple detection circuit comprises a small capacitor placed across the thermocouple leads and driven with a low level current. The low impedance of the intact thermocouple presents a virtual short circuit across the capacitor so it cannot charge. But when a thermocouple opens or significantly changes resistance, the capacitor charges and drives the input to one of the voltage rails, which positively indicates a defective thermocouple.

The company where I am working, their is rosemount 5400 series radar type level transmitter, it is meant to show level of filled tank, but along with the level it is showing temperature also, so my question is how a onon-contact type radar type level transmitter can show temperature even if it does not have any contact with the fluid?
