    工作原理Working Principle

    壓力傳感器是利用硅的壓阻效應和良好的機械特性，應用擴散和離子注入技術將壓敏電阻元件光刻在硅膜上。當被測壓力作用于芯體的敏感元件時，傳感器輸出端會有相應的電壓信號輸出，其大小與所加壓力成正比。
    Pressure sensor utilizes piezoresistance effect and superior mechanical characteristic of silicon, pressure sensitive resistance is photoetched on silicon diaphragm using diffusion and ion-implantation technologies. When measured pressure forced on core s sensitive element, transmitter s output end produces corresponding voltage signal output, in proportion to pressure forced on.

    壓力信號轉換器向壓力傳感器提供恒流源，并把壓力傳感器輸出的微弱電壓信號放大，再經V/I 轉換，輸出4～20mA 恒流信號。

    Pressure signal converter provides constant current supply to pressure sensor, and amplify the electric signal that pressure sensor outputs, via V/I conversion, output 4～20mA constant current signal.

    外型結構及安裝方式Dimensional construction and mounting type
    壓力變送器應盡量安裝在溫度梯度和溫度波動小的測壓點上，同時避免強振動和沖擊。高于溫度使用范圍的介質不應與變送器直接接觸，需安裝散熱器或冷卻裝置連接，測量強腐蝕的介質時變送器應配裝布萊迪公司的化學密封產品使用。
    It is suggested the pressure transmitter be mounted on measuring point with lower temperature gradient and temperature fluctuation, meanwhile avoid vibration and impact. It shall not be directly mounted where temperature limit is exceeded, a cooler or cooling device should be used in the way, Brighty Instruments chemical seal product shall be used for extremely corrosive media.

    負載特性Load Characteristic

   系統連接及調試System connection and adjustment
    變送器在測量系統中的連接見圖，建議電源電壓Us 選用24V。
    Refer to scheme for wiring of the transmitter in measuring system, suggest power supply Us uses 24V.
    二次儀表中采樣電阻（負載電阻）RL 的阻值選用250 Ω。如果Us 和RL 選用別的數值，那么RL 值不能超過由公式計算得到的數值。
    Sampling resistance in secondary instrumen（t load resistance）RL uses 250Ω. If resistance deviates for Us and RL, RL value shall not exceed the value from formula .
    電源通過信號線接到變送器，變送器頂部兩側面的連接孔用電纜密封或信號線裝配，信號電纜通過緊固螺母鎖緊，不用的那個連接口必須密封。
    Power supply is connected to transmitter via signal cable, connections holes at both sides of top of transmitter is sealed with cable or assembled with signal cable, signal cable is fastened by lock nuts, idle connection hole must be sealed.

    出廠前壓力變送器已按訂貨要求調試合格，用戶無需再做調整。長時間使用后如需重新標定，可分別調整“調零電位器”和“調量程電位器”。壓力量程的下限值對應于4mA，上限值對應20mA. （ Z- 調零電位器 S-調量程電位器）
    Before delivery pressure transmitters has been calibrated as per ordering requirement, user doesn’t need adjustment. After long time service, it needs to be recalibrated, which can be done by adjus“t zero potentiometer” and“span potentiometer”. Lower limit represents 4mA, upper limit represents 20mA. （ Z- zero potentiometer S- span potentiometer）

   安裝Mounting
    1. 直接安裝在測量點上（任意角度）。
       directly mount on measuring point（any angle）
    2. 盡量安裝在溫度梯度與溫度波動小的測壓點上，同時避免強振動和沖擊。
       suggest mount on measuring point with lower temperature gradient and temperature fluctuation, meanwhile
avoid vibration and impact
    3. 室外安裝時，盡可能放置于保護盒內，避免陽光直射和雨淋，以保持變送器性能穩定和延長使用壽命。
       in case of outdoor mounting, preferred mounting in protection case, avoid direct exposure to sunlight and rainfall, to maintain transmitter’s functional stability and longer service life.
    4. 測量蒸汽或其它高溫介質時，注意不要使變送器的工作溫度超限。必要時請安裝散熱器或其它冷卻裝置連接。
       when measuring steam or other high temperature media, make sure transmitter’s working temperature limit is observed. Fit cooler or other cooling device if necessary
    5. 安裝時應在變送器和介質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精度。在壓力波動范圍大的場合還應加裝阻尼器或壓力緩沖裝置。
       when mounting, shut valve should be used between transmitter and medium, for easy maintenance and to prevent pressure taking port from blocking that influences measuring accuracy. Damper or pressure buffer should be used where big pressure fluctuation exists
