    它是如何運作的？

    Bronkhorst EL-PRESS壓力感測器是一個位於矽芯片表面的壓阻橋。該芯片在其反面鑽出，使芯片內部形成壓力膜片的形式，其厚度決定了壓力範圍。當壓力作用在這個芯片上時，膜片會彎曲，壓阻橋的電阻值會與壓力成比例地變化。測量單元通過一個薄且靈敏的不銹鋼隔膜與外部壓力隔開，且隔膜和單元之間的密封腔也填滿了注油。
    也可提供其他型號/規格。

    請注意：

    壓力感測器的測量單元通過一個薄而靈敏的不銹鋼隔膜與外部壓力隔開，且隔膜和單元之間的密封腔內填滿了注油。由於標準注油是易燃的，因此 Bronkhorst 建議在使用氧氣或任何其他易爆液體時採取預防措施。

  • EL-PRESS series are equipped with a digital pc-board, offering high accuracy, excellent temperature stability and fast response. The main digital pc-board contains all of the general functions needed for measurement and control. In addition to the standard RS232 output the instruments also offer analog I/O. As an option, an on-board interface can be mounted to provide CANopen®, DeviceNet™, EtherCAT®, PROFIBUS DP, PROFINET, Modbus RTU, ASCII or TCP/IP, EtherNet/IP, POWERLINK or FLOW-BUS protocols.

    Key features of the digital electronic pressure meter include:

    • For absolute or gauge pressure
    • High accuracy and repeatability
    • Well proven, compact thru-flow design
    • On-board PID controller for pressure control
    • Analog, RS232 and fieldbus communication

    How does it work?

    The Bronkhorst EL-PRESS pressure sensor is a piezoresistive bridge on the surface of a silicon chip. This chip is drilled out on its reverse side, giving the inside of the chip the form of a pressure diaphragm, whose thickness determines the pressure range. When a pressure acts on this chip, the diaphragm flexes, and the resistor values of the bridge alter in proportion to the pressure. The measuring cell is separated from the external pressure by a thin, sensitive stainless steel diaphragm, and the sealed off cavity between diaphragm and cell is filled with oil.

    Other models/specifications are also available.

    Please Note:

    The measuring cell of the pressure sensor is separated from the external pressure by a thin, sensitive stainless steel diaphragm, and the sealed off cavity between diaphragm and cell is filled with oil. Since the standard oil filling is flammable, Bronkhorst advises to take precautions when oxygen or any other explosive fluid is used.
