1. The transmitter must be used in a medium that is not corrosive to the sealing material and housing material. 2. When the pressure-guiding hole of the transmitter is blocked, it is strictly forbidden to use a sharp tool to clear the pressure-guiding hole. The transmitter should be removed and the pressure-guiding hole should be immersed in a liquid that can dissolve the blockage. After the blockage is dissolved, remove it fall out. 3. It is strictly forbidden to open the transmitter for calibration or maintenance by yourself. 4. If you are not sure whether the transmitter is suitable for the...
