Product Details

12-32VDC differential pressure sensor with output 4-20mA,1-5V or RS485 and display

Based on piezo-resistive silicon technology, QWB300 differential pressure sensor uses silicon differential pressure sensors

with stainless steel isolated diaphragm as measuring elements. Made from 316L stainless steel and designed of rigid and robust

construction, UPB5 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.

Features:

*Reliable performance, good long term stability*Good static pressure, good ability of anti-impact and overload pressure*Strong reversed polarity protection and current limiting protection*Light weight, easy installation*Integrated stainless steel construction design, small volume
