If you are referring to a two-conductor wire temperature sensor, then the short answer is "No." Each temperature sensor involves interpreting electrical resistance in a closed loop ("closed loop" are the important words). As the temperature rises or decreases, so does the resistance. It is this resistance that is measured in each two-conductor temperature sensor closed loop (notice how I worked in the words "closed loop" again).
If the temperature sensor involves a diode with three leads . . . that is another matter. One of the three leads is the "ground" that may be tied together with another ground lead of another diode temperature sensor.
A two-conductor wire temperature sensor does not have a ground lead.
