Precautions for ordering PT500-706P 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; Low power output power supply range: 3.6vdc (3-5vdc)
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: Whether the flameproof protection level can meet the requirements of field conditions; 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;
Different product signal output specifications correspond to different power supply range requirements; 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;
