PROBLEM TO BE SOLVED: To provide a pressure transducer capable of maintaining highly accurate measurement over a wide temperature range without the need for updating a correction constant or exchanging ROM at the time of new connection or exchange. SOLUTION: A pressure sensor 11 to detect pressure, a temperature sensor 12 to detect temperature, and read-only memory 13 to store correction data characteristic to a pressure sensor are integrated and provided for a pressure transducer. In addition, the pressure transducer is provided with a serial data/ address signal line 14 and a serial clock signal line 15 to transfer the correction data of read-only memory, and an address signal and data signal of the memory are serially transferred in synchronization with a clock signal.
