Two-wire temperature transmitters are widely used in modern industrial measurement and control systems. The transmitter can be combined with a thermal resistor and a thermocouple to linearly convert the temperature signal into a 4-20mA DC standard output current signal and modulate it on two power lines.

How many wires does a temp sensor have?
two
How do you hook up a coolant temperature sensor?
Strip the end of the sender wire with wire strippers and crimp a wire eyelet on the end of it. Place the eyelet over the gauge stud marked "S." Connect it to the sensor probe. Tighten the nut with a socket. Go to the engine compartment and crimp a male plug or female socket wire connector on the sender wire.
Can a coolant temp sensor be wired backwards?
What happens if the Temperature Sensor terminals are connected with the wrong polarity? The measured temperature will not be displayed properly. If the polarity is connected in reverse, the Temperature Controllers will display a falling temperature when the temperature is actually rising.
Do temp sensors have polarity?
No. Thermistors do not have polarity. They are just like resistors, but their resistance changes considerably with temperature.
