Thick Film Ceramic Pressure Sensor

Magnetostrictive liquid level sensor.

Thick film ceramic pressure sensor.

Ess501i ceramic thick film pressure sensor module. Sensors thick film ceramic pressure sensor. Common is that high reliability is required often extended temperature range also along massive thermocycling of circuits without. Mixture of fuel air pressure sensors engine and gearbox controls sensor for releasing airbags ignitors to airbags.

Thick film sensors like thin film sensors use four resistors grouped to form a wheatstone bridge. The resistance change here is also due to the deformation of the diaphragm. Thick film circuits modules are widely used in the automotive industry both in sensors e g. A new type of pressure sensor has been developed by taking advantage of the piezoresistive effect in thick film resistors screened and fired on ceramic diaphragms.

The piezoresistive bridge sensor is made with thick film technology on a face of the diaphragm. Lng vehicle pressure sensor. Ps series ceramic sensor chip has been widely applied in the process control environment control hydraulic pressure and pneumatic equipment servo valve and drive chemical products chemical industry medical instrument and other fields. For use with open semiconductors they are contacted on the ceramic or pcb by wire bonding.

This in turn means a longer service life in particular for high thermal requirements and thermal cycling. Silicon and thick film ceramics follow similar thermal expansion cte patterns. Syz series strain core. The resistance structures are printed onto a base element e g.

The pressure sensors with front membrane are made of a ceramic membrane bonded on a ceramic body and exploit the piezoresistive effect. Hydraulic machinery pressure sensor. Magnetostrictive liquid level sensor. Thick film ceramic pressure sensor.

The wheatstone bridge is screen printed on one side of the flush ceramic diaphragm which is in turn glued to the sensor s body. Syz series strain core. The sensors with front membrane are available for absolute or relative pressure measurement. Ceramic base using thick film technology and afterwards they are burnt in at high temperature.
