Technology The «LC» line of miniature pressure transmitters leverages KELLER’s extensive background in high-stability piezoresistive pressure sensors and innovative digital signal processing. Now, both pressure sensor and signal processor are integrated into a miniature, hermetically-sealed housing no larger than was once required for the sensor only! The name given to this new technology is Chip-In-Oil (CIO). CIO means not only that the entire pressure transmitter is embedded within a hermetically-sealed, oil-filled housing, but that this transmitter can then be seamlessly integrated into the OEM product, achieving cost savings and system performance not possible with other, conventional technologies. Interfaces The ratiometric analog output simplifies the integrators task by providing a signal output wherein the output is ratiometric to the supply, thereby eliminating the need to incorporate an expensive, absolute reference. Providing an 0,5…4,5 VDC output from a 5 VDC supply, the LC-transmitter is inherently protected against overvoltage and reverse polarity up to ±33 VDC and provides noise immunity by a factor of 10X relative to the latest standards regarding emitted and conducted EMI. Performance features

  • Hermetically protected sensor electronics - extremely resistant to environmental influences
  • Operating temperature up to 150 °C
  • Ultra-compact, robust housing made from stainless steel (optionally Hastelloy C-276)
  • No external electronics for compensation or signal processing
  • Extremely accurate, outstanding long-term stability, no hysteresis
  • Pressure ranges of 1 bar to 1000 bar
  • Extremely easy to integrate in overall systems
  • Two-chip solution with pressure sensor and signal processing separation provides a high degree of flexibility. 4LC 8LC 9FLC 7LC 9LC 6LHPC / 7LHPC (High Pressure) Connection 4LC / ø 11 4,2 5 8 8 GNDOUT Supply 9 9 571 0,5 0,5 0,5 7LC / ø 15 8LC / ø 17 9LC / ø 19 ø 5,08 9FLC / ø 17 / ø 21 6LHPC / ø 13 7LHPC / ø 15 Generally applies: No force must be applied to the pins! 3 3
