で形成したことを特徴とする差圧・圧力発信器。 It is connected to the amplifier chamber that houses the amplifier unit that receives the detection signal from the detector side in the transmitter housing and performs arithmetic processing on it, and is equipped with electronic components to prevent external noise from entering the amplifier unit side. A terminal board unit consisting of a printed circuit board and a terminal block mounted on the printed circuit board and having terminals for connecting an external power supply and a remote control unit to the amplifier unit is housed and arranged, and selectively connected to each terminal on the terminal block. A terminal chamber is provided in which a cable entry port from the outside to be connected is opened facing a part of the side wall of the housing, and in this terminal chamber, the external noise is dissipated onto the terminal block mounting surface of the printed circuit board in the terminal block unit. In addition to mounting the blocking electronic components, a protective cover is provided to cover the outside of the terminal block unit, and each terminal is placed close to the terminal block opening formed in a part of the protective cover. A type symbol is displayed, and the side edge of the protective cover close to the cable entry port is formed with a guide surface that guides the cable drawn into the housing toward the terminal block. Differential pressure/pressure transmitter.
