       Double path Piezoresistance Vacuum Gauge   


  The measured atmosphere which normally consists of hydrogen, hydrocarbons, rare gases inside the rough and low vacuum equipment are complex, but the common relative vacuum gauges such as thermal conductivity, thermocouple vacuum gauge, resistance vacuum gauge (Pirani) cannot meet the needs of the complex atmosphere measurement and control because measured value by these gauges is related to the gas composition. Therefore, the piezoresistance vacuum gauge should be chosen to measure and control complex atmosphere.

  The gauge adopts piezoresistance transmitter, and its measured value has nothing to do with the composition of the gas.
  The piezoresistance absolute pressure (vacuum) transmitter is a resistance -strain sensor. The diaphragm of the force deformation is made of 316 stainless steel diaphragm with high stability, small zero drift and super anti-corrosive properties.

  With so many years dedicated research, our company matched precise drive electronics circuits and signal conditional circuits with adopting piezoresistive sensor from international famous company and launched a delicate and high-performance piezoresistance transmitter. Furthermore, in order to adapt to vacuum equipment automation technology,we collect some extensive features such as relay contact control, serial communications, vacuum analog quantity and so on. So the gauge is specially suitable for rough and low vacuum measurement and control.      

  The pressure resistance vacuum gauge realizes two- path measurements. There are two ways to display the measurements. First, a window shows the first measurement and switch to the second by hand(96×96 case). Second, two windows shows the measurements independently.
