Described herein is the sensor assembly and method for rapidly obtaining accurate readings of a variable. The sensor assembly comprises a plurality of sensors which are connected to a microcontroller that processes the signals of the individual transducers to the microcontroller. The microcontroller contains software that maximizes the refresh rate and/or minimizes the time it takes to process the outputs of each of the transducers. The microcontroller that is coupled to the sensor assembly selectively measures the outputs of each transducer so as to speed up the refresh rate of the sensor.

Sensor assembly and method

Described herein is the sense element assembly for a capacitive pressure sensor and method for creating same that has increased sensitivity without additional size. The sense element assembly and method includes fabricating an off-centered elliptically shaped center electrode, at least one elliptical annular-like electrode around the center electrode, a ground electrode and a method for fusing the layers together to optimize sensitivity.

Sensor element assembly and method

An assembly for sensing the dielectric constant of liquids, and for detecting contamination, includes a central ceramic chip with a sensing capacitor formed on one end thereof and a signal processing circuit on the other end thereof. The capacitor is formed of two sets of closely spaced conductive lines or pathways with one set being grounded and the other set providing the variable output from the capacitor to the signal processing circuit.

Precise dielectric constant sensor

A high-sensitivity capacitive oil deterioration and level sensor includes a conductive housing member with an inner surface defining a ground electrode and conductive inner member with an outer surface defining a measuring electrode. The housing member is adapted to provide a fluidic connection between an oil container and a gap between the ground electrode and the measuring electrode. The sensor also includes electronics adapted to employ this capacitor geometry to generate signals indicative of a degree of deterioration and a level of the oil within the gap.

High-sensitivity capacitive oil deterioration and level sensor

A sensor assembly for measuring characteristics of motor oil in a vehicle includes a housing adapted to be mechanically coupled to a vehicle for receiving motor oil of the vehicle and at least one capacitive sensor including sensing electrodes positioned relative to the housing to measure characteristics of motor oil between the sensing electrodes. The sensing electrodes are coated with a soot build-up inhibiting coating which, in a preferred embodiment, is a silicone coating. The at least one capacitive sensor include an oil level sensor and an oil deterioration sensor in a preferred embodiment.
