Tips for Type Selection
* In order to guarantee safe and reliable operation of the transducer, it is recommended that the three-valve manifold should be installed between the point to be measured and the transducer to ensure that the medium to be measured is slowly and evenly applied on the positive and negative chambers.
* During installation, it is recommended that pressure connections on both ends should be located above the horizontal line so as to minimize the influence of the installation position on the product.
* During type selection, please note that the static pressure to be measured shall be less than 20MPa and the overpressure to be applied on the positive and negative chambers shall not exceed the specified value of the product.
* As an additional function code for type selection, the code “E” for intrinsically safe explosion-proof type Ex iaIICT6 denotes that power source must be supplied via safety barrier.
* For other special requirements, please discuss with us and clearly indicate them in the order.
