摘要： Metal face inductive proximity sensors and methods are presented for sensing the presence or absence of a target object in a target sensing area in which a coil system is operated to generate a magnetic field extending outward from the sensing face at a frequency in a range that maximizes a relative target effect for the sensing face area, material, and thickness, and a target material from which the target object is made to allow the protective advantages of metal sensing face materials while enhancing sensing distance by optimizing the ratio of the target energy loss to the energy loss in the metal face.

摘要： Systems and methods are provided for sensing or measuring capacitive or inductive reactance or changes in reactance in which the sensed reactance is coupled with a known resistance in a sensor circuit and a start signal is provided to the sensor circuit, and a programmable delay line is used to generate a programmable delay signal. The outputs of the programmable delay and the sensor circuits are compared to ascertain which transitions first, and the programmable delay value is adjusted in successive approximation fashion to identify a programmable delay that best represents the delay time of the sensor circuit from which the sensed reactance value can be determined.

摘要： An inductive proximity sensor oscillator having a differential comparator in combination with a negative feedback network and a positive feedback network connected to the comparator. The positive feedback network determines the frequency and amplitude of the generated oscillations. An LC resonant tank circuit is connected between a non-inverting input and a fixed reference voltage, and a current limiting resistor connected between the non-inverting input and the output of the comparator. The negative feedback network provides a simple, fast and reliable start-up mechanism. It comprises a capacitor connected between the inverting input of the comparator and the circuit ground and a resistor connected between the non-inverting input and output of the comparator.

摘要： Low voltage logic circuitry is used to permit an entire subsystem of an industrial controller to be placed within a hazardous environment to receive a high speed serial link and undertake the control of multiple control points without expensive and awkward long cable runs and electrically isolating circuits for each cable run. Energy and bandwidth limiting on the high speed link allows power levels commensurate with high data rates yet intrinsic safety of the media allowing it to freely pass in and out of the hazardous area. A mixture of intrinsically safe and non-intrinsically safe equipment on the same logical rack is allowed through a bus isolator providing isolated data communication in backplane fashion between modules while wholly isolating power transmission along the backplane.
