The LJI33 series pressure transmitter adopts an internationally advanced alumina ceramic sensor as the "dry measurement unit", combined with high-precision electronic components, and assembled through strict process. Due to the use of dry pressure measurement technology without intermediate fluid, it has excellent characteristics such as high overload and impact resistance, high stability, and high measurement accuracy. It is particularly suitable for various occasions and media in industrial measurement and is an ideal upgrade product for traditional pressure gauges and pressure transmitters.
