    摘要: Provided are: a vacuum gauge that, with a simple configuration, can accurately diagnose the degree of contamination of the vacuum gauge; and a contamination diagnosis method that, with a simple process, can accurately diagnose the degree of contamination of a vacuum gauge. Provided is a cold cathode ionization vacuum gauge that has a normal operation mode and a contamination diagnosis mode, the cold cathode ionization vacuum gauge comprising: an anode 1 and a cathode 3 that are for measuring vacuum pressure in the normal operation mode; an anode 7 and the cathode 3 that are for measuring the vacuum pressure in the contamination diagnosis mode; and a controller 10 that compares the size of a current measured between the anode 7 and the cathode 3 and the size of a current measured between the anode 1 and the cathode 3.

    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: A capacitor (100) for use in sensors includes opposed first and second capacitor plates (102, 104), wherein the second capacitor plate (104) is mounted to the first capacitor plate (102) by a flexible attachment (108). The flexible attachment (108) is configured and adapted so that flexure of the attachment (108) causes a change in the spacing between the first and second capacitor plates (102, 104) to cause a change in the capacitance thereacross.
