Claims

[Scope of Claim for Utility Model Registration] (1) An amplifier unit that is connected and fixed to the detection unit body side and that receives the detection signal from the detection unit side and processes it, and this amplifier unit has an external power source and a remote control unit. A terminal block unit having terminals for connecting the operating section is installed inside the terminal block unit, and facing the part in which the terminal block unit is installed, a lead-in port for an external cable selectively connected to each terminal is provided at one place on the side wall. The transmitter housing includes a housing body having a substantially bottomed cylindrical shape formed with an opening, and a lid body closing the open end of the housing body, and the housing body constituting the transmitter housing is It is composed of a cylindrical member having a mouth and a cup-shaped bottom lid member connected to the opening at one end of the cylindrical member, and the amplifier unit and the terminal board unit are stacked and fixed to this bottom lid member, and the bottom A differential pressure/pressure transmitter characterized in that the cylindrical member is rotatably fitted into a lid member and integrally connected with a gap and a depth that conform to pressure-resistant and explosion-proof guidelines. (2) It is connected and fixed to the detection part body side and has an amplifier unit inside which receives the detection signal from the detection part side and processes it, and a terminal for connecting an external power supply and a remote control part to this amplifier unit. A terminal board unit and an indicator for displaying the output signal from the amplifier unit through the terminal board unit are installed inside the terminal board unit, and an external terminal facing the part where the terminal board unit is installed and selectively connected to each terminal is provided. A housing body having a substantially bottomed cylindrical shape formed by opening a cable entry port at one location on a side wall, and a transparent plate that closes the open end and allows the indicator to be viewed from the outside. The transmitter housing is comprised of a cylindrical member having the lead-in port and a cup-shaped bottom cover member connected to an opening at one end of the cylindrical member. At the same time, the amplifier unit is attached to this bottom cover member.
The terminal board unit and the indicator are stacked and fixed, and the cylindrical member is rotatably fitted to the bottom cover member, and connected integrally with a gap and depth that meet the flameproof explosion-proof guidelines. Differential pressure, characterized by
pressure transmitter. (3) It is connected and fixed to the detection part body side, and has an amplifier unit inside which receives the detection signal from the detection part side and processes it, and a terminal for connecting an external power supply and a remote control part to this amplifier unit. A terminal board unit and an indicator for displaying the output signal from the amplifier unit through the terminal board unit are installed inside the terminal board unit, and an external terminal facing the part where the terminal board unit is installed and selectively connected to each terminal is provided. A housing body having a substantially bottomed cylindrical shape formed by opening a cable entry port at one location on a side wall, and a transparent plate that closes the open end and allows the indicator to be viewed from the outside. The transmitter housing is comprised of a cylindrical member having the lead-in port and a cup-shaped bottom cover member connected to an opening at one end of the cylindrical member. At the same time, the amplifier unit is attached to this bottom cover member.
Terminal board units are stacked and fixed, and a cylindrical member with the indicator fixed thereto is rotatably fitted to the bottom cover member, and the unit is integrated with a gap and depth that meet the flameproof and explosion-proof guidelines. A differential pressure/pressure transmitter characterized by being connected to.
