    Ordering considerations
    Precautions for ordering PT500-704 pressure transmitter

    1. Product range selection:
    In order to achieve the best effect of product accuracy, service life, stability and other functions, the range selection of the product
    Select the following formula for calculation:
    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;
    Low power rs485-rtu output, DC 3.1-6.1vdc;
    When output rs485-rtu, please understand the communication protocol first;

    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;
    Whether the installation space meets the overall dimension of the product;

    Precautions for use

    Precautions for PT500-704 pressure transmitter
    Please refer to the product certificate and instructions for power supply. Different output modes and different power supply voltages are required;
    It is strictly forbidden to use hard objects (such as: screwdrivers, fingers, nails, etc.) to make the pressure measurement output of the pressure core body;
    The power supply and signal lines shall be correctly connected according to the product specifications;
    When the product is installed and used, protect the cable air duct, which is strictly prohibited from water entering or blocking;
    It is strictly prohibited that the medium temperature, pressure range and excitation voltage of the measured system exceed the rated range of the transmitter;
    Pay attention to protect the outgoing cable of transmitter. When the span is too large, it is recommended to use metal tube for protection or overhead;
    When measuring the water level of wells, groundwater, rivers and reservoirs, pay attention to the input position of sensors to avoid the height of sludge;
    For a large range of water level products, when the cable length is more than 30 meters, the liquid level transformer can not be directly pulled by the cable;
    When measuring the water level with rapid water flow, the liquid level transmitter is installed along with the limit pipe to ensure that the product does not float;
    In order to reduce the information interference and ensure the measurement accuracy, the installation position of the transmitter should avoid the equipment with large magnetic field change and radiation as far as possible, such as motor, submersible pump, high-voltage cable, etc;
    Field installation transmitter, add lightning rod and other protective devices;
