    Ordering considerations
    1. Product range selection:
    In order to achieve the best effect of product accuracy, life, stability and other functions, the range selection of the product is calculated by referring to the following formula:
    Range = x (1.2-1.5) times of the maximum system pressure;
    The actual measuring pressure range of the product should be 15% - 80% of the range;

    2. Signal output mode of the product:
    The signal output specification depends on the requirements of the back-end acquisition equipment;
    Common are: control and display instrument, PLC acquisition and input module, MCU acquisition card, PC serial port, etc
    If the back-end acquisition equipment is determined according to the output specification of the product, it is recommended to use the general two-wire system 4-20mA;

    3. The user should understand the measurement medium characteristics of the product:
    Medium specification, medium temperature, medium purity (whether containing impurities or particles, etc.);

    4. Users should understand the installation environment and installation mode of the product:
    Indoor or outdoor installation;
    Ambient temperature;
    Required sealing level;
    Vibration range of equipment;
    Installation method: thread, flange, special structure;
    Whether the installation space meets the overall dimension of the product;

    5. When the product is installed and used at a high place outside, lightning protection device shall be installed;

    6. When the product is used to measure the liquid level, please explain when ordering the product, so as to support the air conducting cable;
    Precautions for use
    Product power supply 24VDC (range: 9-30vdc);

    It is strictly prohibited to use hard objects (such as screwdriver, finger, iron nail, etc.) to make the pressure core body under pressure measurement output;

    The power and signal wires shall be correctly wired according to the specifications of the ordered products;

    When the product is installed, the stressed part is "process connection hexagon wrench position", and the wrench specification corresponds to hexagon;

    It is strictly prohibited that the medium temperature, pressure range and excitation voltage of the tested system exceed the rated use range of the transmitter;

    Pay attention to protect the outgoing cable of the transmitter. When the span is too large on site, it is recommended to use metal pipe for protection or overhead;

    The pressure transmitter is a precision measuring instrument, do not impose impact or smash to avoid damaging the core;

    When the product is applied to the liquid level measurement, pay attention to the air conduit of the air conducting cable, do a good job of protection, and do not soak or water;

    The product is installed in a ventilated and non corrosive environment, and installed in the open with protective devices to avoid direct sunlight;
