Silicon Pressure Transmitter
Brand: Xi'an UTOP Measurement Instrument Co, Ltd
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 1 bar~0, 0~0.1 till 1000 bar, 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.
Features- Wide measuring pressure range: -1...0~0.1...1000 bar
- Against thunder stroke, against radio-frequency interference
- Full stainless steel construction
- Reversed-polarity, transient current & voltage protection
- Suitable for the measurement of low pressure and vacuum pressure
- Anti-corrosion, anti-attrition, anti-impact
