    Ordering considerations
    Precautions for ordering PT500-590 products

    1. Product range selection:
    In order to achieve the best effect of product accuracy, service life, stability and other functions, the range of the product is calculated according to the following formula:
    Range = x (1.2-1.5) times the maximum pressure of the system;
    The actual measuring pressure range of the product should be 15% - 80% of the measuring range;
    Temperature range: distinguish between measuring temperature and medium. The required product is measuring medium temperature or testing ambient temperature. Explain the situation with the salesperson when ordering;

    2. Product power supply and output:
    The selection of power supply range is determined according to the output specifications of the product:
    A. Built in battery 3.6v1200mah;
    B. External 5VDC power supply;
    C. External 9-24vdc power supply;
    Conventional Modbus rs485-rtu low-power digital output;
    5-digit LCD display meter; The default acquisition time is 1s / time;

    3. Users need to understand the characteristics of the measuring medium of the product:
    Medium specification, medium temperature, medium purity (whether it contains 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 grade;
    Vibration range of equipment;
    Installation method: thread, flange and special structure;
    Whether the installation space meets the overall dimension of the product;

    Precautions for use

    Product power supply range, internal battery power supply: 3.6vdc, external power supply 5VDC or 24VDC;

    It is forbidden to use hard objects (such as screwdriver, finger, iron nail, etc.) to make the pressure diaphragm subject to pressure measurement output;

    The battery installation, external power supply and signal line shall be wired correctly according to the specifications of the ordered products;

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

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

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

    The pressure transmitter is a precision measuring instrument. Do not impose impact and beating to avoid damaging the core

    The product is installed in a ventilated, dry and non corrosive environment. Protective devices are installed in the open air to avoid direct sunlight;

    Water / water leakage / soaking is strictly prohibited for product instruments. Protective devices shall be installed in the open air to avoid direct sunlight;
