The BY-CEC-DR micro differential pressure transmitter is a new type of transmitter produced by our company through the introduction of foreign technology and equipment. The key raw materials, components, and parts are all imported, and the whole machine has undergone strict assembly and testing. This product has the characteristics of design principles, complete varieties and specifications, and easy installation and use. Due to the complete integration of the structural advantages of two popular and widely used transmitters (Rosemount 3051 and Yokogawa EJA) in the appearance of this model, users have a refreshing feeling. At the same time, it can be directly replaced with traditional 1151, CECC and other series products in installation, with strong versatility and substitution ability. 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.
