摘要: The invention relates to a method for testing a temperature-compensated, pressure-gradient-controlled pressure switch (1), which is pneumatically associated with a primary pressure chamber (2) and has a secondary pressure chamber (3) for temperature compensation, wherein a temperature gradient is set between the primary pressure chamber (2) and the secondary pressure chamber (3) by using at least one temperature control device (4, 5), which temperature gradient is sufficiently large to produce a pressure gradient, which corresponds at least to the triggering pressure gradient of the pressure switch (1), between the primary pressure chamber (2) and the secondary pressure chamber (3).

摘要: A respiratory apparatus (100) for providing therapy for a patient with disordered breathing comprises a flow generator having a blower (130) to generate a flow of breathable gas for a patient interface at a pressure above atmospheric pressure, and one or more sensors (104, 106, 108, 110). The one or more sensors (104, 106, 108, 110) are configured to respectively output measurement of one or more of:
a pressure of the flow of breathable gas;
a temperature of the flow of breathable gas;
a speed of a motor of the blower (130); and
a flow rate of the flow of breathable gas.
The respiratory apparatus (100) further comprises a processor (116) configured to determine an estimate of an altitude of the respiratory apparatus (100) based on the output measurement from the one or more sensors(104, 106, 108, 110). The processor (116) is configured to control the blower (130) based on the estimate of the altitude.-

摘要: A method of determining a faulty sensor of a sensor array of a gas turbine engine (10), the sensor array comprising at least first, second and third sensors (A, B, C), the method comprising the steps of:
a. measuring a first set of sensor outputs (S1 A , S1 B , S1 C ) prior to engine startup from each sensor (A, B, C), and calculating a first difference (S1 A -S1 B , S1 A -S1 C , S1 B -S1 C ) in the measured value for each sensor pair (A;B, A;C, B;C);
b. after a period of time, measuring a second set of sensor outputs (S2 A , S2 B , S2c) prior to engine startup from each sensor (A, B, C), and calculating a second difference (S2 A -S2 B , S2 A -S2 C , S2 B -S2 C ) in measured value for each sensor pair (A;B, A;C, B;C);
c. calculating a further difference ((S1 A - S1 B ) - (S2 A - S2 B ), (S1 A - S1 C ) - (S2 A - S2 C ), (S1 B - S1 C ) - (S2 B - S2 C )) between the calculated first and second differences for each sensor pair (A;B, A;C, B;C); and
d. identifying a failed sensor (A, B, C) where two or more sensor pairs (A;B, A;C, B;C) comprising a common sensor (A, B, C) have a further difference above a predetermined threshold.摘要翻译: 一种确定燃气涡轮发动机(10)的传感器阵列的故障传感器的方法,所述传感器阵列包括至少第一,第二和第三传感器(A,B,C),所述方法包括以下步骤:a。 在来自每个传感器(A,B,C)的发动机启动之前测量第一组传感器输出(S1A,S1B,S1C),并且计算测量的第一差值(S1A-S1B,S1A- S1C,S1B- 每个传感器对的值(A; B,A; C,B; C); 湾 在一段时间之后,在发动机起动之前从每个传感器(A,B,C)测量第二组传感器输出(S2A,S2B,S2c),并且计算第二差值(S2A-S2B,S2A-S2C,S2B (A; B,A; C,B; C)的测量值中的传感器对(-S2C)。 C。 计算所计算的第一和第二差值之间的另一差值((S1A-S1B) - (S2A-S2B),(S1A-S1C) - (S2A-S2C),(S1B-S1C) - (S2B-S2C)) 传感器对(A; B,A; C,B; C); 和d。 识别其中包括公共传感器(A,B,C)的两个或更多个传感器对(A; B,A; C,B; C)具有高于预定阈值的进一步差异的故障传感器(A,B,C)。
