The ST3351 (3051/1151) miniaturization series intelligent capacitive transmitter is an advanced technology and equipment introduced by our company from abroad. The key raw materials, components, and parts are all imported, and the whole machine has undergone strict assembly and testing. It has the characteristics of advanced design principles, complete varieties and specifications, and easy installation and use. Due to the complete integration of two popular and widely used transmitters (Rosemount 3051/1151 and Yokogawa EJA) in the appearance of this model, it gives users a refreshing feeling. At the same time, it is easily compatible with traditional 1151, CECC and other series products in installation and can be directly replaced, so it is a replacement and update product for some old models. In order to adapt to the continuous improvement and development of domestic automation level, this series of products not only has a compact and exquisite design, but also introduces intelligent functions with HART fieldbus protocol.
