Pressure Cells

Semiconductor Type | Model 3500

  • Model 3500 Series Semiconductor Pressure Cells.
  • Model 3500 Earth Pressure Cell installed under railroad tracks.
Model 3500

The 3500 Series is similar in design to the 4800 Series but the vibrating wire transducer is replaced by a semiconductor type transducer (to enable the measurement of dynamic pressures) which can have an output of 2 mV/V, 0-5 VDC or 4-20 mA. Typical applications are the measurement of traffic induced stresses on roadway sub grades, airport runways or under railroad tracks.
