ME504 - Piezoresistive Flush Membrane

Metallux ME504 pressure sensors are made with a ceramic base plate 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 solvents and acids, etc.), no additional protection is usually required. On the sensor body, the layout is optimized to allow easy mounting of signal conditioning PCB when requested.

Laser-adjustable PTC resistors thermally compensate Metallux ME504 sensors, and ceramic ensures high linearity across the entire range of measurement, reducing the effects of hysteresis to a minimum.
