RK300-12 Differential Pressure Transmitter
PRODUCT DESCRIPTION
Based on piezo-resistive silicon technology,differential pressure transmitter uses silicon differential pressure sensors with stainless steel isolated diaphragm as measuring elements. Made of 316L stainless steel and designed of rigid and robust construction, which has a feature of that zero point and full range can be adjusted. It 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.
