The Metallux SA ME509 are piezoresitive ceramic pressure sensors specially designed for level measurement applications. The cell diameter is 32.4mm, a well known standard for low pressure range and high-performance applications. The measuring bridge is directly printed on one side of a ceramic diaphragm by means of thick film technology.The rear side of the flat diaphragm can be exposed directly to the medium without any additional protection due to the excellent chemical resistance of the ceramic.The ME509 is available  for Absolute or Gauge pressure. Typical ranges: 200 and 500 millibar full-scale. Other ranges available upon request.
