Silicon Pressure Transmitter
Description
UPB1 silicon pressure transmitter, based on piezo-resistive silicon technology, 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 this 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 pressure transmitter features integrated construction, high measuring accuracy, good long term stability, and it is suitable for pressure measurement in general industry applications.
