Industrial process control, as a field of endeavor, is a continuous quest for better, safer, and higher output. The road of progress is paved with new technologies that deliver higher accuracy and reliability in measurement. A recently commercialized advance is the silicon resonant sensor used to measure pressure in industrial process settings. One manufacturer, Yokogawa, applies this technology throughout their DPharp line of differential pressure transmitters, with numerous industrial applications.

Some of the positive attributes of this latest generation of digital pressure sensor include:


  • Simultaneous measurement of differential and static pressure.
  • Superior digital precision
  • No A/D conversion needed
  • High performance 
  • Temperature effects limited to 10 ppm/deg Celsius, yielding highly stable performance
  • High signal to noise ratio
  • Output level increase of more than four times over previous generation piezoresistance silicon sensor

The features all add up to a substantial improvement over previous technology, delivering an incremental step up in measurement performance and confidence.
