    Ordering considerations
    Precautions for ordering PT500-561 RS485 Low power digital pressure transmitter
    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:
    Power supply range 3.1-6.1vdc:
    Low power RS485-rtu output;
    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;
    Pressure seal: taper seal, face seal, arc seal, spherical seal;
    Whether the installation space meets the overall dimension of the product;

    Precautions for use
    Precautions for using PT500-561 RS485 low power digital pressure transmitter
    Product power supply 3.6vdc (range: 3.1-6.1vdc);
    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, the stress part is "process connection hexagonal wrench", and the wrench size is corresponding to the hexagonal wrench;
    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;
    Pressure transmitter is a kind of precision measuring instrument. Do not force impact and fall to avoid damaging the core
    The product is installed in a ventilated, dry and non corrosive environment. It is installed in the open air with protective devices to avoid direct sunlight;
