Silicon Differential Pressure Transmitter
Brand: Xi'an UTOP Measurement Instrument Co, Ltd
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.
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
