摘要： An engine exhaust emission control device determines a differential pressure across a diesel particulate filter (DPF) to enable regeneration of the DPF at optimal timing. An ECU estimates the temperature of a differential pressure sensor provided for the DPF from the output of an intake air temperature sensor when the engine is not running, and determines an offset correction factor for correcting the sensor's offset error. The factor is set using the sensor output at this time as sensor's offset error, and stored in a memory. When detecting the differential pressure across the DPF, the temperature of the sensor at this time is estimated, and an offset correction factor that corresponds to this estimated temperature is selected. The sensor outputs are adjusted with this offset correction factor.

摘要： The full bridge circuit in a pressure sensor including semiconductor piezoelectric resistive elements in a pressure detection structure is connected to a filter. That is, first and second output terminals of the full bridge circuit is connected to a capacitor. One end of the capacitor is connected to the first output terminal through a first resistor. The other end of the capacitor is connected to the second output terminal through a second resistor. In an exhaust system of an engine, the pressure of the exhaust gas is detected to detect clogging in the black smoke removing unit. The filter removes the pulsate component in the detection signal derived from the pulsate component in the exhaust gas.

摘要： A semiconductor sensor chip includes a thin diaphragm and an electrical circuit formed on a front surface of the diaphragm. The diaphragm distorts according to a pressure difference between pressures applied on both surfaces of the diaphragm, and the diaphragm distortion is converted into an electrical signal. Both surfaces of the diaphragm are covered with protecting members to protect the sensor chip from dusts and moisture contained in the gas. Since the gas is introduced to the rear surface of the diaphragm through a small passage while the front surface receives pressure with a relatively large area, the protecting member covering the rear surface is made softer than that covering the front surface. Thus, the sensor chip is properly protected against dusts and moisture.

摘要： A pressure detecting apparatus includes a sensing body with a diaphragm to which pressure is applied and a strain gauge plate having a {100} silicon substrate and a glass base, which is bonded on the sensing body. A thin portion and through holes are formed in the silicon substrate so that the thin portion has a beam structure on which strain gauges are formed. When the pressure is applied, the resistances of the strain gauges change in a positive direction, while the resistances of the strain gauges change in a negative direction. Accordingly, the linearity of the output from the pressure detecting apparatus can be improved.

摘要： A pressure sensor has a housing (1). The housing accommodates a pressure sensing element (2) and a wiring board (3). The wiring board incorporates a lead irame (14). The lead frame connects output terminals (21) of the sensing element with ends of connector pins (12). A pressure guide (4) has a pressure path (41) and a flange (44). The flange is inserted in an opening of the housing with the pressure path being airtightly connected to a pressure intake (22) extending from the sensing element and with an end face (4a) of the flange being spaced apart from the wiring board. Potting material (5) coats the sensing element, the wiring board, and the flange of the pressure guide in the housing. If the potting material peels off the flange, water may penetrate the peeled part and reach the end face of the flange. The water, however, never reaches the wiring board because the end face of the flange is spaced apart from the wiring board. Accordingly, the lead frame in the wiring board is free from water and no migration is caused.
