摘要： A capacitive pressure sensor of substantially ceramic material comprises a thick base plate (100), a front plate (140) having the same thickness as the base plate and a movable diaphragm (120) located between the front plate and the base plate. Capacitor electrodes (121b, 121a) are provided at the surface of the diaphragm facing the base plate and form a measurement capacitor. The diaphragm (120) is extremely thin and is produced by sintering a ceramic material such aluminium oxide. Owing to a pressing process used during the sintering a strong, very thin diaphragm is obtained having no mechanical stresses and fracture indications. It can be produced to have a very small thickness in order to provide pressure sensors having a high sensitivity, which can also for high-vacuum applications tolerate to be subjected to the atmospheric pressure. A shielding plate (110) can be inserted between the base plate (100) and the diaphragm (120) in order to provide both electrical shielding and to form a reference capacitor having a reference pressure for compensating the measurement capacitor. The shielding plate (110) can also be extremely thin, having a thickness down to a thickness corresponding to the thickness of the diaphragm (120).
摘要翻译：基本上陶瓷材料的电容式压力传感器包括厚基板（100），具有与基板相同厚度的前板（140）和位于前板与基板之间的可动隔膜（120）。电容器电极（121b，121a）设置在面对基板的隔膜的表面，并形成测量电容器。隔膜（120）非常薄，并且通过烧结陶瓷材料来制造这种氧化铝。由于在烧结期间使用的压制方法，获得了不具有机械应力和断裂指示的强而非常薄的隔膜。为了提供具有高灵敏度的压力传感器，可以制造具有非常小的厚度，这也可以耐受大气压力的高真空应用。屏蔽板（110）可以插入在基板（100）和隔膜（120）之间，以便提供电屏蔽并形成具有用于补偿测量电容器的参考压力的参考电容器。屏蔽板（110）也可以是非常薄的，具有厚度对应于膜片（120）的厚度的厚度。

摘要： A capacitive sensor element (1') for pressure sensors comprises a house part (3') based on electrically isolating materials such as glass ceramic material and the house part (3') has on an interior surface one capacitor plate (9). An opposite capacitor plate (11) is attached to one side of a diaphragm (7) of an electrically isolating material, which on its other side has an electrically conductive shielding layer (21) that is intended to be connected to ground. The capacitor plates (9, 11) form an electrical capacitor, the capacitance of which is changed when the distance between the plates vary. A second electrically conductive shielding layer (17) is surrounded by the material in the house part (3'), between a shielding plate (15) and a thick support plate (13) at some distance from the one capacitor plate and it has a significantly larger extension laterally than this plate. Also this layer (17) is intended to be connected to ground. By arranging this interior ground plane (17) near the capacitor plates (9, 11) they are ensured a uniform electrical surrounding for reduction of the influence of stray capacitances. Further, the thick support plate (13) gives the house part a good mechanical stability.

摘要： According to the invention a pressure gauge is provided comprising a sensor housing (1) closed by a cover (7). The sensor housing (1) is connected to a tube (3) containing the pressure to be measured. The space defined by the sensor housing (1) and the cover (7) is hermetically divided by a sensor housing cover (9) in such a way that inside a front measurement volume (11) a pressure sensor means (15) is placed. This pressure sensor means has a substantially flat shape. It is connected to the interior walls of the front volume by means of tubes (23) which are slender or slim, that is have a small section in relation to the area of the pressure sensor means (15). The carrying means (23) are preferably realized as metal tubes and in their interior the electrical connections (31) for the pressure sensor means pass. By this construction the exterior surface of the whole of the pressure sensor means (15) will be subjected to the measuring pressure. Further an attachment to the pressure sensor housing is provided only allowing a slight convection of heat and in addition the measuring volume does not contain any chemically unstable materials. The electrical connections are also well protected against corrosion by the measurement medium and obtain an electrical shielding.

摘要： In a chemical heat pump a substance is used which within the temperature range for which the heat pump is intended has a transition between a solid phase and a solution phase. The substance can for a solar driven chemical heat pump comprise magnesium chloride hexahydrate. In an accumulator part of the heat pump a heat exchanger (21) is provided enclosed by a net (23). The solid phase is primarily located inside the net in contact with the heat exchanger while the solution phase flows out of the net and is collected in a space (24') below the heat exchanger. From this space the solution phase is pumped and sprayed over the heat exchanger from a spray bar (25). Thereby, all the time the equilibrium between the solution phase and the solid phase is maintained. The advantage including the constant temperature step ( DELTA T) and the relatively large energy content of solid substances is thereby combined with the high power of liquid substances. Such a chemical heat pump is among other things suitable for converting low grade heat energy such as solar energy to cooling and in some cases also for a simultaneous production of heat.

摘要： A capacity pressure sensor having a housing (101) and a diaphragm (103). The housing (101) and the diaphragm (103) are substantially flat and are connected to each other at an upstanding border (106) at the periphery of the housing (101). In the hermetically closed space (7) between the housing (101) and said diaphragm (103) a reference pressure is applied. In a pressure measurement the diaphragm (103) is bent inwards relative to said housing (101) depending on the pressure acting on the surface of said diaphragm (103). This bending inwards is a primary output signal which capacitively can be converted to an electrical signal. Inside the pressure on the inner surfaces of said housing (101) and said diaphragm (103) there are arranged, for the detection of the position of said diaphragm (103) relative to said housing (101), capacitor plates (109, 111) connected to an electrical measuring circuit for detection of the capacity of the capacitor formed thereby. To enhance the linearity of the measuring capacitor the outer flat surfaces of the pressure sensor are coated with conducting layers (121, 123) connected to earth. Furthermore, in the house (101) a recess (123) is arranged which when given suitable dimensions further reduces the deviation of the pressure sensor from the desired linear characteristic.
