Ceracore technology

Our basic technology for your success

The Ceracore 4.0 is based on a capacitive measuring principle. In this case, the main body and membrane act as components of a capacitor. If pressure is applied to the sensor, the distance between the two electrodes changes due to the deflection of the membrane. This leads to a change in capacity, which is converted via the transmitter into an electrical output signal. Capacitive ceramic sensing technology offers a number of advantages.

Design and function of the capacitive ceramic measuring cell

Advantages of ceramic technology:
  • Patented metallic active solder connection of sensor base element and membrane
  • Metallic coating of the sensor base element for improved EMC compatibility and reduced installation sensitivity
  • Made of high-purity ceramic (99.9% Al2O3), highly resistant and chemically neutral to a wide range of process media
  • As a dry measuring cell without the use of oils for pressure transmission, the Ceracore is absolutely vacuum-resistant
  • Highest overload resistance
  • High reference accuracy of 0.1%

Security:

  • Self-monitored measuring cell for maximum safety
  • Communication via secure protocols
  • Improved EMC resistance (guarding)
  • Approved z. Eg ATEX, …
  • RoHS
  • FDA listed materials

Application-specific configuration:

  • Sensor pre-configured at the factory (damping, turn-down, measuring range, …)
  • Adjustable measuring rate for optimal resolution / power consumption
  • Customer-side configuration possible
  • Output of the pressure and temperature signal possible
  • Power consumption 2.5 to 10 mW
  • Various sizes (diameter: 17.5 mm and 32.4 mm)

Communication:

  • Analog output signal – voltage output ratiometric or voltage output absolut
  • Digital output signal – SPI or UART interface
  • Digital and analog output signal combinable
  • switching output
  • temperature output
