ESS501 Ceramic Thick Film Pressure Sensor
ESS501 Ceramic Thick Film Pressure Sensor Cell (both Monolithic and Flush Diaphragm) are made with a ceramic base plate and diaphragm and work following the piezoresistive principle.
The Wheatstone bridge is screen printed on one side of the flush ceramic diaphragm which is, in turn, glued to the sensor’s body. The bridge faces the inside where a cavity is made and the diaphragm’s opposite side can therefore be exposed directly to the medium to be measured.
