RTDs can be interconnected using two, three, or four wires. Two wires are the lowest cost method, but are less accurate than the more expensive four wire connection.

Digital signal transmission has higher signal integrity and is faster than analog signal transmission and can use error correction codes to correct for any errors in transmission.
