    Ordering considerations
    Precautions for ordering PT500-2088 products
    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. Product power supply and output:
    The selection of power supply range is determined according to the output specifications of the product:
    Conventional 4-20mA / 0-20mA, 0-5V / 10V output, DC 12-30vdc power supply;
    General rs485-rtu output, DC 12-30vdc power supply;
    0.5-4.5vdc output, DC 5VDC;

    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 method 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;

    Precautions for use
    Product power supply range, 9-30vdc ;
    It is strictly prohibited to use hard objects (such as screwdriver, finger, iron nail, etc.) to make the pressure diaphragm output under pressure measurement;
    The power and signal wires shall be correctly wired according to the specifications of the ordered products;
    During product installation, 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
    The product is installed in a ventilated, dry and non corrosive environment, and installed in the open with protective devices to avoid direct sunlight;
    It is strictly prohibited to enter / leak / soak water in the product instrument, and protective devices shall be installed in the open to avoid direct sunlight;
