The key raw materials, components, and parts of the PTH1151/3351DP differential pressure transmitter are all imported or jointly produced, and the entire machine has undergone strict assembly and testing. This product features advanced design principles, complete variety and specifications, and easy installation and use. Due to the complete integration of the structural advantages of the two most popular and widely used transmitters in China (Rosemount 3051 and Yokogawa EJA) in terms of appearance, this model provides users with a refreshing feeling and has strong versatility and substitutability. 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.
