Ceramic Differential Pressure Sensor Flush Diaphragm ME800

ME800 Ceramic Differential Pressure Sensor Flush Diaphragm

Properties
Pressure Medium: Air/Gas, Harsh & Liquid Environments
Sensor Type: Differential
Supply Voltage: Under 5V, 5V
Output Signal: Millivolt
Pressure Range: 3-300 psi
Kind: Ceramic

A ceramic base plate working as a flush diaphragm using the piezoresistive principle composes the Metallux differential pressure sensors. The Wheatstone bridge is screen-printed on one side of the base plate, which is then glued to a ceramic ring to allow proper diaphragm flexing. A special coating protects the bridge, which can therefore be exposed directly to the medium being measured.
