The isolator film may be used to protect the sensor from corrosive and high temperature fluids, for example to protect the sensor from long term exposure to hot water between 85° C. and 100° C. | 04-14-2016 |
| 20160138992 | METHODS OF FORMING A CONDITIONED ISOLATION ELEMENT FOR A SENSOR ASSEMBLY, AND RELATED CONDITIONED ISOLATION ELEMENTS AND SENSOR ASSEMBLIES - A method of forming a conditioned isolation element for a sensor assembly comprises subjecting a preformed isolation element structure to at least one thermal annealing process to form a conditioned isolation element structure substantially less susceptible to at least one of hydrogen permeation, hydrogen-based embrittlement, and hydrogen-based stress-cracking. Conditioned isolation elements and sensor assemblies are also described. | 05-19-2016 |
| 20160146688 | Iodine-Resistant Pressure Sensor Assemblage - A pressure sensor assemblage includes a housing and a pressure sensor received in an interior space of the housing. The housing has at least one gas inlet that is connected in gas-permeable fashion at least to a sub-region of the interior space of the housing. In addition, a sacrificial element is provided at the gas inlet, which element is disposed and implemented in such a way that gas flowing through the gas inlet comes into contact with a surface of the sacrificial element, which surface of the sacrificial element is provided with a silver layer. The sacrificial element has a carrier element made of an iodine- or iodide-resistant material. | 05-26-2016 |
