Spot™ CDS500D


The Spot CDS500D suspended ceramic capacitance diaphragm sensor is designed for integration into the limited space in your specific vacuum instruments and systems. The miniature sensor is highly corrosion resistant as the alumina ceramic cell, the suspension and a weldable stainless steel feedthrough are all alumina coated. The sensor electronics provide a digital SPI interface for easy integration. The sensor features a fast data cycle time for instant response to pressure changes, outstanding repeatability and long-term stability. The sensor is provided in two versions, either factory calibrated with customer flange or preadjusted with custom flange.


  • Miniature Alumina (Al2O3) ceramic coated capacitance diaphragm sensor is highly corrosion resistant with UHP compliant wetted surface
  • Excellent repeatability and long-term stability
  • Weldable feedthrough for custom integration and calibration, or welded custom flange for integration of factory calibrated sensor
  • Sensor electronics with SPI interface for easy integration
  • Fast response time
  • High overpressure capability

Typical Applications

  • For integration into custom vacuum instrumentation and systems
