), product overview) series of intelligent pressure transmitters use a piezoresistive sensor with a stainless steel isolation diaphragm as the signal measurement element, which has been automatically tested by a computer and compensated for zero point and sensitivity in a wide temperature range using a laser resistance trimming process. After passing through the signal processing circuit, it is converted into a standard signal output. The product has been strictly screened through processes such as long-term aging and stability assessment, and its performance is stable and reliable. It is used in open-air sites with relatively harsh environments and requires on-site observation of pressure display, zero point migration and range adjustment. It is suitable for process control and pressure measurement in petroleum, chemical industry, metallurgy, electric power, light industry, textile, building materials, hydrogeology, food, medicine, environmental control and other industries.
