摘要： A sensing assembly (10) senses a level (24) of a liquid (22) in a reservoir (12). The sensing assembly (10) includes a first input port (32) for receiving a first input voltage signal. The sensing assembly (10) also includes a second (32) input port (36) for receiving a second input voltage signal. An excitation circuit (40) is electrically (36) connected to the first (32) and second (34) input ports for receiving the first (34) and second (38) input voltage signals and for generating a first excitation signal and a second excitation signal. A receiving circuit (50) is disposed adjacent the excitation circuit (40) and defines a variable capacitance with the excitation circuit (40). The receiving circuit (50) produces an output voltage variable with the level (24) of the liquid (22) in the reservoir (12) due to capacitance changes between the excitation circuit (40) and the receiving circuit (50). The receiving circuit (50) includes a first receiving electrode (54) extending through a sine wave form and a second receiving electrode (56) extending through a cosine wave form. The capacitance changes are due to dielectric changes created by the presence of the liquid (22) adjacent at least a portion of the sensing assembly (10).

摘要： An oil level sensor for a vehicle includes a receiver tube oriented upright in the oil pan of the vehicle. A level tube is disposed in the receiver tube and below the level tube is a reference tube. A circuit is electrically connected to the tubes for outputting a signal representative of oil level in the oil pan. As the engine oil level decreases within the level tube, the output of the sensor drops. When the engine oil level is below the bottom of the level tube but higher than the top of the reference tube, the output reaches the lowest value. As the engine oil level continuous decreasing (below the top of the reference tube), the output increases for a first circuit configuration (i.e., level with reference tube), and will stay constant for the second configuration level.

摘要： A viscosity sensor for, e.g., outputting a signal representing the viscosity of engine oil has one or more piezoelectric diaphragms disposed in a fluid chamber of a housing. An elongated amplification channel is formed in the housing and extends away from the chamber. The diaphragm can be excited to induce fluid movement that in turn induces the diaphragm to output a sensor signal representative of the viscosity of the fluid.

摘要： A sensor circuit is coupled to a sensing element for determining a property, such as a dielectric constant, of a fuel suitable where the dielectric constant is used in determining a concentration of ethanol in the gasoline/ethanol blended fuel. The circuit includes an excitation voltage signal generator, a synchronization trigger and a processing circuit configured to generate an output signal indicative of the fuel property (dielectric constant). The excitation voltage signal is applied to the sensing element to produce an induced current signal therethrough. The synchronization trigger is configured to generate a trigger signal when the excitation voltage signal crosses zero volts, at which time the real (resistive) component of the induced current signal is zero. The induced signal is therefore wholly representative of the imaginary component attributable to a capacitance of the sensing element in sensing relation with the fuel, which in turn is dependent on the dielectric constant (and thus ethanol concentration) of the fuel blend itself. The processing circuit is configured to sample the induced signal in response to the trigger signal and produce the output signal. The synchronization scheme provides for a simplified circuit arrangement since there is o need to decompose a signal combining real and imaginary components.

摘要： Soot content in Diesel engine lubrication oil is determined using electrical resistance measurements of the oil at high frequency. A sensor in the form of a capacitor is immersed in the oil, wherein the oil serves as a dielectric between the plates. The capacitance and resistance between the plates change as a function of engine oil condition. An inductor is placed in series with the sensor, and high frequencies are sweeped over a range to find resonance where the capacitive and inductive reactances cancel. At this frequency, the resistance of the oil is measured and the condition of the oil thereby determined.
