The YH1151/3351LT flange pressure/level transmitter adopts a differential capacitive pressure sensor, which can accurately measure the pressure of various containers. There are flat flanges and plug-in flanges. The flange has 3 inches or 4 Inches, the specifications have flanges of 1501b and 3001b, and flanges can also be customized according to users, and flange diaphragm materials are optional.
The key raw materials of YH1151/3351LT flange pressure/level transmitter. The components and parts are all imported or joint ventures. The whole machine has been rigorously assembled and tested. The product has advanced design principles, complete varieties and specifications, and installation and use. Convenience and other features. 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 it is in line with the traditional series. The product can be directly replaced in installation, and has 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.
This product is widely used in petroleum, chemical, sewage treatment, urban water supply, machinery, metallurgy, electric power, scientific research and other enterprises and institutions to realize the measurement of liquid, gas or steam pressure, and is suitable for all-weather environments and various corrosion in various occasions Measurement and control of the pressure of sexual liquids, gases, and vapors.
