    摘要： A wireless field device for use in an industrial process control system includes a power source having a power source output. Field device is circuitry powered by the power source output. A protection circuit is configured to protect the field device circuitry. The protection circuit include reverse polarity protection circuit coupled to the power source output that electrically isolates the power source output from the field device circuitry in response to a reverse polarity connection between the power source output and the field device circuitry. An overvoltage protection circuit disconnects the power source output from the field device circuitry is a voltage of the power source output exceeds a threshold.

    摘要： An electronic circuit for converting higher-frequency output signals from a sensor into lower-frequency input signals for a discrete input wireless transmitter. The circuit includes a differential amplifier, a digital comparator, a digital frequency divider, and a transistor switch. The differential amplifier amplifies the sensor signals as a function of a frequency of the sensor signals. The digital comparator generates a square wave signal by comparing the amplified sensor signals to a fixed reference voltage. The digital frequency divider generates a lower-frequency signal by dividing the square wave signal. The transistor switch generates the lower-frequency input signals for the discrete input wireless transmitter by switching as a function of the lower-frequency signal from the digital frequency divider.

    摘要： Embodiments of methods and apparatuses for producing styrene are provided. The method comprises the steps of introducing ethylbenzene to a first dehydrogenation reactor containing a first high activity dehydrogenation catalyst at a first predetermined inlet temperature to form a first intermediate effluent stream that comprises styrene, ethylbenzene, and hydrogen. Oxygen is added to the first intermediate effluent stream to form a first oxygenated intermediate effluent stream. The first oxygenated intermediate effluent stream is introduced to a first oxidation-reheat dehydrogenation reactor at a second predetermined inlet temperature of about 530° C. or less to form styrene. The first oxidation-reheat dehydrogenation reactor contains a first oxidation catalyst and a second high activity dehydrogenation catalyst.
