HYODA INSTRUMENTS CORPORATION19隔膜式圧力計DIAPHRAGM-SEALED TYPE PRESSURE GAUGES□15隔膜式圧力計Diaphragm-Sealed Type Pressure Gaugesこの圧力計は測定しようとする流体とブルドン管圧力計との間を波状ダイアフラムで仕切り、この間に圧力伝達用の特殊な液体を封入した構造のものをいいます。このため測定流体が直接圧力計内部(株及びブルドン管)へ入りません。ダイアフラム及び接液部はブルドン管のように優れた弾性特性を要求されることがないので、測定流体に応じた材質を選定できます。従って強腐食性流体の計測に適し、さらに接続口径を大きくできる特長を利用して、高粘度流体、固形物を含んだ流体の計測にも使用可能です。特長 ●腐食性、高粘度の流体圧測定に最適である。●零調指針を用いておりますので温度誤差、エレベーションエラー(高位差)等の補正が容易にできます。●一部材質を除き、ダイアフラムは溶接式ですので締付ボルトをゆるめることによりダイアフラム面の洗浄が容易にできます。また、溶接式ですので封入液の漏れの心配もありません。This gauge is structurally partitioned off between themeasuring fluid and a Bourdon tube pressure gauge by awavelike shape diaphragm and the special liquid forpressure transmission is filled into its space.Consequently, the measuring fluid does not directly enterinto the socket and the Bourdon tube of the inside ofpressure gauge. In other words, the wetted parts of socketand Bourdon tube keep away measuring fluid. Asdiaphragm and wetted parts are not required superiorelasticity as if Bourdon tube has it, they are able to bechosen as to materials responded to measuring fluid.Accordingly,it is suitable for measurement of very strongcorrosive fluid and also it is available to measure highviscous fluid and solid matter including it by the way ofutilizing a special merit that is makes connecting bore larger.Advantages●It is the most suitable use of pressuremeasurement for corrosive and high viscousfluid.●The correction for temperature, elevationerror etc. is easily possible because ofadapting zero-point adjusting pointer.●Cleaning of diaphragm face is easilypossible because of welding type as todiaphragm after loosening the setting boltsexpect any diaphragm materials. It is noproblem not to leak the filled liquid due towelding type, still more.
