The key raw material ZRN1151GP pressure transmitters, components and parts are derived from imported or joint venture, the whole assembly and rigorous testing. The product has advanced design principles, full of different specifications, easy installation and so on. Because the machine Appearance on the full integration of the currently the most popular, the two transmitters (Rosemount 3051 and Yokogawa EJA) and widely used structural advantage, allowing users to have a fresh feeling, and has a strong versatility and Alternative ability to fit the domestic level of automation of the continuous improvement and development, the series of products in addition to design compact, but also introduced a HART field bus protocol intelligent features.
