| 不銹鋼膜盒電接點壓力表概述 不銹鋼膜盒電接點壓力表是根據(jù)不銹鋼膜盒壓力表的結(jié)構(gòu)原理而研制的具有耐腐蝕的微壓測量儀表。導(dǎo)致系統(tǒng)及外殼均采用不銹鋼材料制成，儀表經(jīng)與相應(yīng)的電氣器件配套使用，可達到對被測壓力系統(tǒng)實現(xiàn)預(yù)先設(shè)定和最大或最小壓力值的雙位自動控制和發(fā)信（報警）的目的。 無錫市希爾特壓力表廠專業(yè)生產(chǎn)銷售不銹鋼壓力表、黃銅管、煉膠機、液位計、耐震壓力表。 結(jié)構(gòu)原理 儀表由測量系統(tǒng)（包括接頭、膜盒）、傳動機構(gòu)、指示裝置、磁助電接點裝置、外殼、調(diào)節(jié)裝置及航空扦等組成。 當被測介質(zhì)的壓力作用于膜盒時，其自由端產(chǎn)生相應(yīng)彈性變形一位移，經(jīng)拔桿帶動傳動機構(gòu)放大，由指示裝置將被測壓力在儀表度盤上指示出來。同時指針帶動電接點裝置的活動觸點與設(shè)定指針上的觸點（上限或下限）相接觸的瞬時，致使控制系統(tǒng)接通或斷開電路，以達到自動控制和發(fā)信報警的目的。 (圖/文www.milkteethmovie.com) 英文版： The stainless steel film electric contact pressure gauge overview The stainless steel film electric contact pressure gauge is based on the structure and principle of the stainless steel film pressure meter is designed with micro pressure measuring instrument for corrosion resistance. Cause system and shell are made of stainless steel material, instrument with the corresponding supporting the use of electric devices, can be achieved on the measured pressure system to achieve pre-set and minimum or maximum pressure value of the double position automatic control and signalling (alarm) purpose. Wuxi xierte pressure gauge factory specializing in the production and sales of stainless steel pressure gauges, brass, mixer, liquid level meter, vibration proof pressure gauge. The structure principle This instrument consists of measuring system (including joint, the membrane box), gear, indicating device, magnet electric contact device, housing, adjusting device and aviation skewer etc.. When the pressure of the measured medium to the film box, the free end of the elastic deformation and displacement, the transmission mechanism is driven by the pull rod amplifier, by indicating device indicates the pressure will be on meter dial. At the same time the pointer to the movable contact of electric contact device contacts on setting the pointer (upper or lower) of instantaneous contact, the control system is switched on or off circuit, in order to achieve the purpose of automatic control and alarm. |
