Precautions for PT500-602 level 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;
