Uncompensated Medium-Pressure Core (RS PC160)

RS PC160 oil-filled medium-pressure cores support ranges up to 160bar, with 160bar available for absolute pressure only. 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

Applications

  • Fluid control
  • Process control
  • Pressure transmitters
  • Robotics
  • Refrigeration equipment
  • Air compressors
  • Level measurement
  • Replacement of imported products

Features

  • Miniature all-welded design without sealing rings; designed for more than 20 million pressure cycles.
  • Overload design of ≥3×FS across the series.
  • Repeatability ≤±0.02%FS, typical.
  • Hysteresis ≤±0.01%FS, typical.
  • 500G mechanical shock capability — IEC 60068-2-27:2008.
  • Pressure response as fast as 1.4μs.
