摘要： System and methods for determining a concentration of urea in an aqueous solution disposed in a container are provided. The system includes an infrared light source and an infrared light detector. The system further includes a window disposed proximate to an aperture of the container, such that the infrared light at a first light intensity level from the infrared light source passes through a first portion of the window toward the aqueous solution. A portion of the infrared light is absorbed by the aqueous solution, and a second portion of the infrared light is reflected from the aqueous solution and through a second portion of the window. The infrared light detector system generates a first signal indicative of a second light intensity level based on the second portion of infrared light. The system further includes a microprocessor that determines the second light intensity level based on the first signal, and further determines a urea concentration based on the first and second light intensity levels.

摘要： A transmission clutch position sensor includes two Hall sensors located at opposite ends of a flux concentrator outside the casing of the transmission to sense a magnetic field generated by a magnet attached to the clutch piston. To reduce sensitivity to magnet-to-sensor gap tolerances, a ratio of the voltage of one Hall sensor to the sum of the voltages from both Hall sensors is used to correlate to the piston and, hence, clutch position.

摘要： A fuel sensor includes a cylindrical, one-piece plastic body that has an inlet, an outlet and a fuel passage in between. The body further includes three sensing, thin-walled plate holders that extend from the cylindrical body into and across the fuel passage. Three parallel sensing plates are disposed in the holders for use in forming a pair of parallel plate devices. The thin-walled plate holders surrounding the plates provide isolation of the plates from contact with the fuel. The body also includes a cavity to house a printed circuit board (PCB), which includes signal processing circuitry. The PCB is also isolated from exposure to the fuel. The sensing plates have leads that extend into the cavity for connection to the PCB. An interface connector for connection to an engine controller is also provided. The sensor achieves isolation from exposure to fuel without the use of any coatings.

摘要： A capacitive pressure sensor includes a electrically conductive, generally piston shaped diaphragm with a flexible base wall configured to deflect under pressure. The diaphragm is generally U-shaped in cross section. The base wall includes an upper, flat sensing surface which acts as a capacitive electrode. The diaphragm further includes a step around a radially-outermost perimeter which is elevated from the flat sensing surface. A sensing electrode body is located on top of the step and creates a capacitive sensing cavity between the sensing surface and the bottom surface of the electrode body. On the bottom surface of the electrode body is formed a center, circular electrode and a ring electrode that surrounds the center electrode. The center electrode and the sensing surface form a variable capacitor which changes with pressure and the ring electrode and the sensing surface form a reference capacitor. A circuit determines a differential capacitance between the variable capacitor and the reference capacitor and generates a pressure signal indicative of the fluid pressure applied to the diaphragm. A spring ring holds the sensing electrode body against the diaphragm when assembled. The diaphragm can be a machined metal part or a sheet metal cup. The sensing electrodes and signal generating circuit can take the form of a hybrid circuit.

摘要： MOSFETs are provided to connect the sensor input terminals of a ratiometric output sensor to a pair of power terminals, and the gate of each MOSFET is coupled to the opposite power terminal so that both MOSFETs are rendered conducting to power the sensor when a supply voltage of a predetermined polarity is connected across the power terminals but one of the MOSFETs is rendered non-conducting when a voltage of the opposite polarity is so applied. The MOSFET that is rendered non-conducting is oriented so that any internal source-drain diode does not bypass current around the MOSFET when voltage of the opposite polarity is applied. Optionally, over-voltage protection is provided by an input voltage sensor controlling the other MOSFET through a third MOSFET.

The viscometer may also include a thermally insulating jacket disposed around the heating element and the fluid flow channel. A method of measuring viscosity with the viscometer includes immersing a fluid flow channel in the fluid, heating a portion of the fluid in the fluid flow channel near the inlet end of the fluid flow channel, and measuring a temperature of the fluid in the fluid flow channel at a position downstream from the inlet end of the fluid flow channel. The method further includes recording temperature changes of the fluid for a time period and comparing recorded temperature change characteristics to known fluid viscosities to determine viscosity.

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).
