Silicon - sapphire semiconductor sensitive element manufacturing pressure sensors and transmitters

Silicon - sapphire semiconductor sensitive element manufacturing pressure sensors and transmitters, can work in the harshest working conditions andhighreliability, good accuracy, the temperature error is extremely small, cost-effective.Gauge pressure Engine Temperature Sensors and transmitters by a double diaphragm components: titanium and titanium alloys measuring diaphragm receiving diaphragm. Heteroepitaxial printed bridge circuit of strain sensitive foil sapphire, titanium is welded to the measuring diaphragm. Measured pressure on the diaphragm to the receiver (receiver between the diaphragm and the measuring diaphragm connected together with sturdy rod). Under the action of pressure, the diaphragm is deformed alloy receiver, the deformation by silicon - sapphire perception sensitive element, its output will change the bridge, the magnitude of change is proportional to the measured pressure.
