Precautions
1.When the product range is within -5~5kPa, and the product can only measure non-corrosive gases.
2.If the product will be immersed or submerged, please order liquid level outlet type products, or consult Huatian.
3.Product sealing ring material and tested media compatibility, please contact Huatian for consultation.
4.The installation interfaces on both sides ensure coaxial, free from excess external stress.
5.The maximum static pressure of the product measurement environment needs to be within the range specified by the transmitter.
6.Please install a balance valve in an easy single overvoltage measurement systems.
7.When installing, the spanner shall be used on the hexagon of the pressure joint close to the thread, and the indicator should not be used as a focal point to prevent the failure of the product from sealing.
