Uncompensated Low-Pressure Core (RS PC070)

RS PC070 oil-filled low-pressure cores support a minimum range of 1psi as a custom option. Selected high-quality piezoresistive dies, advanced packaging processes and a proprietary patented oil-filled structure deliver high accuracy and reliability, with excellent pressure hysteresis and repeatability. The series is suited to replacing high-end imported oil-filled pressure products.

The core is uncompensated. Two configurations are available:

  • MEMS oil-filled core — the customer designs the pressure connection
  • MEMS oil-filled core — supplied with a pressure fitting or sealed enclosure

Applications

  • Fluid control
  • Process control
  • Pressure transmitters
  • Robotics
  • Level measurement
  • Replacement of imported products

Features

  • High accuracy and high stability.
  • Overload design of ≥3×FS across the series.
  • Repeatability ≤±0.05%FS, typical.
  • Hysteresis ≤±0.02%FS, typical.
  • 500G mechanical shock capability — IEC 60068-2-27:2008.
  • Pressure response as fast as 1.4μs.
