ME504
Metallux
ME504 pressure sensors are made with a ceramic base cell and a flush 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. Because of the Al2O3 ceramic excellent chemical
resistance (aggressive gases, most of solvents and acids, etc.), no additional
protection is normally required. On the sensor body, layout is optimized to
allow easy mounting of signal conditioning PCB when requested. Metallux ME504
sensors are thermally compensated by laser-adjustable PTC resistors and the use
of ceramic ensures a high linearity across the entire range of measurement,
reducing effects of hysteresis to a minimum.
