Investigation of low-temperature cofired ceramics packages for high-temperature SAW sensors
Surface acoustic wave (SAW) temperature sensor devices have been developed for operating temperatures up to and above 1000 C. A challenging task to make these devices available on the market is to develop an appropriate housing concept. A concept based on low-temperature cofired ceramics (LTCC) has been investigated and tested under elevated temperatures up to 600 C. The devices showed promisin...
متن کاملIon Plating Can Improve Coating Adhesion
1. Easy to plate: steel, copper and brass. These can be coat* with adherent deposits that will riot fail at the deposit-substrate interface. 2. Special treatment: stainless steels, aluminum, beryllium, magnesium and plastics. These can also be coated with adherent deposits that will not fail at the deposit-substrate interface. 3. Very difsicult: titanium, molybdenum, tungsten, niobium, tantalum...
متن کاملHigh Temperature SAW Gas Sensor on Langasite
Novel Surface Acoustic Wave (SAW) devices using the new langasite (LGS) family of crystals have been designed, fabricated, and tested for high temperature (up to 750°C) gas sensor applications. The devices were fabricated using platinum (Pt) and palladium (Pd) thin film technology and were mounted in a high temperature sealed stainless steel chamber for gas testing. The high temperature SAW sen...
متن کاملHigh temperature LGS SAW gas sensor
Novel surface acoustic wave (SAW) devices using the recent langasite (LGS) family of crystals have been designed, fabricated, and tested for high temperature (up to 750 ◦C) gas sensor applications. The devices were fabricated using platinum (Pt) and palladium (Pd) thin film technology as electrodes and sensing films to withstand temperatures in excess of 1000 ◦C. Combinations of platinum and pl...
متن کاملMaterials issues of SAW sensors for high-temperature applications
The technology of surface acoustic wave (SAW) devices allows the integration of signal processing and sensor functions within one product. In the past, SAW sensors have been operated at room temperature or 100 C–200 C at most. Material-related problems become obvious if one attempts to increase this operating temperature to a value as high as 1000 C. First experimental results will be presented...
