、この封液流路内に設置され上記圧力変換部に連結され
るとともに上記受圧要素にディスクを介して連結されて
いる連結軸を設け、この連結軸の一端部をこの一端部に
段落を形成するようにして縮径して嵌合部を形成し、こ
の嵌合部に上記封液流路を絞るダンパーリングを外嵌さ
せ、このダンパーリングによって区切られた上記封液流
路の一方と他方とを連通ずる開封液流路を設け、この開
封液流路の流通断面積を変えるダンパー弁をよ記副封液
流路の途中に設けてなり、上記受圧要素に加えられる流
体の差圧または圧力を上記連結軸を介して上記圧力変換
部で変位または力として検出するとともに上記ダンパー
弁を操作して上記開封液流路の流通断面積を変えること
により流体の突変する圧力によって内部に生じる不所望
な脈動を減衰させることのできる差圧・圧力伝送器にお
いて、上記ダンパーリングの両側部に柔軟性のシールリ
ングを介在させたことを特徴とする差圧・圧力伝送器。A pressure-receiving element is provided on the side, a pressure converter is provided inside, a sealing liquid flow path is provided that communicates between the pressure converter and the pressure-receiving element, and the sealing liquid flow path is installed and connected to the pressure converter. At the same time, a connecting shaft is provided which is connected to the pressure receiving element via a disk, and one end of the connecting shaft is reduced in diameter to form a step at the one end to form a fitting part. A damper ring that restricts the sealing liquid flow path is fitted onto the fitting part, and an opening liquid flow path is provided that communicates one of the sealing liquid flow paths separated by the damper ring with the other, and the opening liquid flow path is provided. A damper valve is provided in the middle of the sub-sealing liquid flow path to change the flow cross-sectional area of the fluid, and the differential pressure or pressure of the fluid applied to the pressure receiving element is transferred to the pressure converter through the connecting shaft to cause displacement or force. A differential pressure/pressure transmitter capable of attenuating undesirable pulsations occurring internally due to sudden changes in fluid pressure by detecting the change in pressure and operating the damper valve to change the flow cross-sectional area of the opening fluid flow path. A differential pressure/pressure transmitter characterized in that flexible seal rings are interposed on both sides of the damper ring.
