Kaidi KD Pressure/Differential Pressure Transmitter Protection level dⅡBT4, iaⅡCT5 for liquid, gas or steam

The key raw materials, components and parts of the YH1151/3351 differential pressure/pressure transmitter are all imported or produced by joint ventures, and the whole machine has been strictly assembled and tested. The product has the characteristics of advanced design principles, complete varieties and specifications, and easy installation and use. Because the appearance of this model completely integrates the structural advantages of the two most popular and widely used transmitters (Rosemount 3051 and Yokogawa EJA), it gives users a refreshing feeling and has a strong Versatility and substitution capabilities. In order to be suitable for the continuous improvement and development of the domestic automation level, this series of products not only has a small and exquisite design, but also has an intelligent function with HART fieldbus protocol.
