In pursuit of excellence, we are striding forward with robust momentum and writing the new chapter for the industry. We have established a good mechanism to shorten the time for customers to select and compare one by one when purchasing the whole batch of products.
Silicon Differential Pressure Transmitter
Description of silicon differential pressure transmitter
Based on piezo-resistive silicon technology, UPB5 silicon differential pressure transmitter uses silicon differential pressure sensor with stainless steel isolated diaphragm as measuring elements. Made from 316L stainless steel and designed of rigid and robust construction, UPB5 silicon differential pressure transmitter is suitable for application in harsh environment and measurement with corrosive pressure media.
This product has widely been used for measurement of differential pressure of pipeline fluids in
petroleum industry, chemical industry, electric power hydrology etc.
