Thick Film Ceramic Pressure Sensor

This in turn means a longer service life in particular for high thermal requirements and thermal cycling.

Thick film ceramic pressure sensor.

Magnetostrictive liquid level sensor. Common is that high reliability is required often extended temperature range also along massive thermocycling of circuits without. Magnetostrictive liquid level sensor. The pressure sensors with front membrane are made of a ceramic membrane bonded on a ceramic body and exploit the piezoresistive effect.

Ceramic base using thick film technology and afterwards they are burnt in at high temperature. Thick film sensors like thin film sensors use four resistors grouped to form a wheatstone bridge. The sensors with front membrane are available for absolute or relative pressure measurement. 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.

Silicon and thick film ceramics follow similar thermal expansion cte patterns. The piezoresistive bridge sensor is made with thick film technology on a face of the diaphragm. For use with open semiconductors they are contacted on the ceramic or pcb by wire bonding. Syz series strain core.

Thick film circuits modules are widely used in the automotive industry both in sensors e g. Lng vehicle pressure sensor. The resistance structures are printed onto a base element e g. 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. 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. Based on metallux me501 505 ess501i pressure sensor module is made with a ceramic base cell and a flush diaphragm and work following the piezoresistive principle. Ess501i ceramic thick film pressure sensor module.

With the characteristic of small dimension 18 mm diameter 6 35 mm thickness 2 200bar range high performance price ratio it has been widely used in. Syz series strain core. Mixture of fuel air pressure sensors engine and gearbox controls sensor for releasing airbags ignitors to airbags. Sensors thick film ceramic pressure sensor.
