2 Wire Temp Sensor Wiring Diagram. The addition of a third wire, connected to one side of the measuring element, helps to compensate for the lead resistance. Please note that if the power applied
There are three types of wire configurations, 2 wire, 3 wire, and 4 wire, that are commonly used in rtd sensing circuits. They can be wired in a sinking (npn) or. Use of 2 wire temperature sensors is highly recommended.
