Tips of Selection
It is recommended that three – valve set should be installed between the point to be measured and the transducer to make sure the medium to be measured is slowly and evenly applied on the positive and negative chambers in order to ensure running safety and reliability of the transducer. It is recommended that the pressure ports on both ends should be located above the horizontal line so as to minimize the influence of the installing position to the product when installing. Please pay attention to the static pressure to be measured shall be less than 20MPa and the over pressure applied on the positive and negative chamber shall not exceed the specified value of the product when selecting. The code E, an additional functional code for selection, and intrinsically safe explosion-proof Ex ia II CT5 must be power supplied via safety barrier. Please contact us in case of the other special requirements and clearly indicate them when placing an order.
