8 Precautions
8.1 Please pay attention to the compatibility of the tested medium and the shell when selecting the model. If you are not sure, please refer to the medium compatibility table on the back cover of the manual or consult our company.
8.2 Please indicate the appropriate temperature range and accuracy requirements when ordering.
8.3 When ordering a transmitter product with a meter, the power supply of the transmitter should not be less than 15VDC.
8.4 When selecting digital display products, the working environment temperature range of the display head is -30℃～60℃.
8.5 Sealing measures are taken at the interface connection to prevent leakage of pressurized liquid and cause pollution or accidents.
8.6 When using in a dangerous environment such as flammable and explosive, please install a safety isolation barrier as required, and the cable connection must be sealed and reliable. Tighten the junction box cover before energizing work to ensure that the inner cavity of the junction box is isolated from the environment. When cleaning, repairing or modifying parameters, you must completely power off, remove the transmitter, and move to a safe environment for disposal. Live operation on site is strictly prohibited.
