       Easy to install, reasonable and compact structure, small weight.

    工作原理Working Principle
    被測介質(zhì)的壓力直接作用于傳感器的陶瓷膜片上，使膜片產(chǎn)生與介質(zhì)壓力成正比的微小位移，正常工作狀態(tài)下，膜片位移不大于0.025毫米，電子線路檢測這一位移量后，即把這一位移量轉(zhuǎn)換成對應(yīng)于這一壓力的標(biāo)準(zhǔn)工業(yè)測量信號。超壓時膜片直接貼到堅(jiān)固的陶瓷基體上，由于膜片與基體間隙只有0.1 毫米，因此過載時膜 片的位移只能是0.1 毫米，所以從結(jié)構(gòu)上保證了膜片不會產(chǎn)生過大變型，由于膜片采用高性能的工業(yè)陶瓷，因而使傳感器具有很強(qiáng)的抗沖擊及抗過載能力。

    The pressure of the medium direct effects the ceramic film of the transmitter and makes the film gets a little displacement. In the common condition, the displacement is less than 0.025mm and the electron wires can get the information of the displacement and transform it to be a standard industry measuring digital. Because the distance between the film and the ceramic body only is 0.1mm, the biggest displacement for the over pressure is 0.1mm. And the transmitter has the ability to resist the strong concussion and over loading.

   安 裝Installation notes
    1. 直接安裝在測量點(diǎn)上（任意角度）。
       Direct install to the measuring point（any angles）.
    2. 盡量安裝在溫度梯度與溫度波動小的場合，同時避免強(qiáng)振動和沖擊。
       It is better to be with less temperature fluctuation and avoid the strong vibration.
    3. 測量蒸汽或其它高溫介質(zhì)時，注意不要使變送器的工作溫度超限。必要時，請安裝散熱裝置或其它冷卻裝置連接。
       While measuring the high temperature mediums, please do not exceed the temperature limitation. If necessary, fit it with cooling devices.
    4. 安裝時應(yīng)在變送器和介質(zhì)之間加裝壓力截止閥，以便檢修和防止取壓口堵塞而影響測量。在壓力波動范圍大的場合還應(yīng)加裝阻尼器或壓力緩沖裝置。

       Add pressure cut-off valve between the transmitter and the medium and add the dampers if the pressure changes a lot.
