摘要： A measuring device (1) for at least indirectly determining the quantity of fuel delivered during the operation of a fuel injection valve (2) comprises a measuring plunger (42) and a detection device (65). The measuring plunger (42) can be placed in a fuel duct section (12) and displaced therein. The detection device (65) serves to detect a displacement of the measuring plunger (42) inside the fuel duct section (12) during the operation of the fuel injection valve (2) and determines a fuel quantity value according to the detected displacement of the measuring plunger (42). The fuel quantity value indicates, at least approximately, a quantity of fuel conveyed through the fuel duct section (12) by the displacement of the measuring plunger (42). The measuring plunger (42) is subjected to the action of a pressure spring (55) with a restoring force whereby being displaced up to a starting position, and comprises a through-opening (67, 68), which acts like a throttle and which permits a restoring movement of the measuring plunger (42) when fuel is flowing through.

摘要： A novel flow rate sensor high in pressure resistance, which has such a structure as to facilitate the measurement of a minuscule differential pressure for measurement of a very small flow rate, is disclosed. A chamber (20) is defined into a primary chamber (21) and a secondary chamber (25) by two diaphragms (31, 32) arranged in an opposed relation to each other. A fluid is passed from the primary chamber to the secondary chamber through a bypass (35) having an orifice portion (40) thereby to generate a differential pressure. The load generated by the fluid pressure fluctuations received by the first and second diaphragms is detected as a difference of displacement by a load difference sensor (50) arranged between the first and second diaphragms thereby to detect the flow rate of the fluid. Displacement limiting members (61, 62) are provided for the diaphragms or the load difference sensor so that the displacement due to the fluid pressure fluctuations received by the first and second diaphragms may not exceed a predetermined amount.

摘要： A miniaturized, inexpensive instrument for measuring the mass flow rate of powder, which is capable of directly outputting the mass flow rate of powder and whose characteristics are not influenced by the kind and physical properties of the powder. The instrument can be easily manufactured, installed, operated, and maintained, and the color can be easily changed. An apparatus for dispensing powder, which is constructed based on this mass flow rate measuring instrument and an electrostatic powder coating system utilizing this supply apparatus and having a high performance and a high effective operation factor are also provided. A gas to be measured, the flow rate of which is regulated, is turned into a thin-layer high-speed gas stream by a dispersion means, powder is cross-dispersed and introduced into a measuring conduit, the differential pressure occurring is measured, and a supply means is subjected to feedback control so that the output of the differential pressure agrees with a set level.

摘要： A pressure transducer (10) having a redundant fluid pressure sensor can be used to determine if the pressure transducer needs to be recalibrated. The pressure transducer comprises a fluid pressure sensor (210) for measuring differential pressure. The fluid pressure sensor includes a pair of substantially identical pressure sensors (212,214) for providing a variable electrical output as a function of a differential fluid pressure and a reference sensor (C R ) for providing an electrical output independent of the differential fluid pressure. A conditioning circuit is provided for generating a frequency-based signal whose frequency is a function of the electrical output for each fluid pressure sensor. The electrical output of the first and second pressure sensors can be compared to determine whether the pressure transducer needs to be calibrated. In one embodiment, the pressure sensors comprise variable capacitors (CS 1 , CS 2 ). The first and second capacitors each have one fixed plate (130,134) and one movable plate (124,126) responsive to differential fluid pressure across the movable plate. The reference capacitor has two fixed plates (132,135). The first variable, second variable, and reference capacitors are all located in proximity to one another and in communication with the differential fluid pressure. The pressure transducer also includes a switching network (174) connected to the capacitors for selectably connecting at least one of the capacitors to an electronic circuit.
