Quick delivery
Based on piezoresistive silicon technology, UPB1 silicon pressure transmitter uses isolated stainless steel diaphragm as sensing element. This product is fully tested by computer automatically, and trimmed by laser for zero and sensitivity in a wider temperature range. Its amplifier circuit is built in stainless steel housing, to transform sensor signal into standard output signal. This transmitter features integrated construction, rigid and robust, high measuring accuracy, good long term stability, and is suitable for pressure measurement in general industry applications.
This product is widely used for pressure measurement and control of petroleum, chemical-industry, metallurgy, power station and hydrology, etc.
Features:
*Full stainless steel construction
*Suitable for the measurement of low pressure and vacuum pressure
*Automatic testing, laser trimming compensating zero & sensitivity
*Against thunder stroke, against radio-frequency interference
*Anti-corrosion, anti-attrition, anti-impact
*Reversed-polarity, transient current & voltage protection
