Ceracore Technology

Our basic technology for your success

Ceracore 4.0 is based on the capacitive measuring principle. The substrate and the diaphragm serve 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 diaphragm. This leads to a change in capacitance which is converted into an electric output signal via evaluation electronics. The capacitive ceramic measuring technology offers a couple of advantages.

Advantages of the ceramic technology:

  • Patented metallic active solder connection of sensor substrate and diaphragm
  • Metallic coating of the sensor substrate for improved EMC and reduced installation sensitivity
  • Produced of ultra pure ceramics (99.9% Al2O3), highly resistant against the most varied process media and chemically neutral
  • The Ceracore dry measuring cell does not use any oil for pressure transmission and is absolutely vacuum resistant
  • Highest overload resistance
  • Linearized and temperature-compensated output signal
  • Low measuring ranges (> 50 mbar)

Safety:

  • Self-monitoring measuring cell for the highest degree of safety

  • Communication via safe protocols

  • Improved EMC (guarding)

  • Approval capability, e.g. ATEX, ...

  • FDA-listed materials

  • RoHS conformity

Application-specific configuration:

  • Sensor preconfigured at the factory (attenuation, turn-down, measuring range, ...)
  • Adjustable measuring rate for optimum resolution/power consumption
  • Option of configuration by customer
  • Output of pressure and temperature signal possible
  • Power consumption 2.5 to 10mW
  • Different design sizes (diameters: 17.5mm and 32.4mm)

Communication:

  • Analog output signal - voltage output ratiometric or 10...90% of supply voltage (2.9...5.5  supply)
  • Digital output signal - SPI or UART interface
  • Digital and analog output signal may be combined
  • Switching output
  • Temperature output
