Precautions for use
Please refer to the product qualification certificate and instructions for product power supply. Different output methods may result in different power supply voltages;
It is strictly prohibited to use hard objects (such as screwdrivers, fingers, nails, etc.) to measure the output of the pressure core body under pressure;
The power and signal cables are correctly wired according to the specifications of the ordered product;
When installing and using the product, protect the cable air duct, and strictly prohibit water ingress or blockage of the cable air duct;
It is strictly prohibited for the medium temperature, pressure range, and excitation voltage of the tested system to exceed the rated range of use of the transmitter;
Pay attention to protecting the outgoing cables of the transmitter. When the span is too large for on-site use, it is recommended to use metal pipes for protection or overhead;
When measuring the water level of wells, groundwater, rivers, reservoirs, etc., pay attention to the placement of sensors to avoid the height of silt;
When the length of the cable exceeds 30 meters for a large range of water level products, the liquid level transformer cannot be directly pulled by the cable;
When measuring the water level with high water flow, the liquid level transmitter is installed with a limit pipe to ensure that the product does not float;
The installation position of the transmitter is to minimize information interference and ensure measurement accuracy, and to avoid equipment with large magnetic field changes and radiation as much as possible, such as motors, submersible pumps, high-voltage cables, etc;
Install transmitters in the field, and add protective devices such as lightning rod;
