Silicon Pressure Transmitter
Description
Based on piezo-resistive silicon technology, UPB1 silicon pressure transmitter uses isolated stainless steel diaphragm pressure sensor as sensing element. By adopting high performance IC, its amplifier circuit is built in stainless steel housing, to transform sensor mV signal into standard output signal.
The pressure range of UPB1 silicon pressure transmitter is very wide from 1bar~0, 0~0.1 till 1000bar, and the pressure types include vented gauge pressure, absolute pressure and sealed gauge pressure. This silicon pressure transmitter features integrated construction, high measuring accuracy, good long term stability, and it is suitable for pressure measurement in general industry applications.
