In an extremely tight race, Filner defeated Republican Carl DeMaio, who, if successful, would have become the first openly gay Republican mayor of a major US city. Other Democratic wins were in Baton Rouge, LA; Honululu, HI and Portland, OR. Mesa, Arizona, re-elected its Republican mayor, while the Republican mayor of Virginia Beach will serve for another four years. The Tea Party suffered a notable setback in Troy, Michigan.
For example if the maximum supply voltage limit of the pressure transmitter is 28Vdc and the power supply produces 30 Vdc to the series loop circuit you would need to add a load resistance of at least 500 ohms in order to prevent the voltage across the pressure transmitter exceeding 28 Vdc at the minimum current of 4mA (i.e. 30 Volts â (500 ohms x 4 ...
Below shows the voltage drop across a load resistor in a series current loop circuit at the minimum current of 4 mA and the maximum current of 20 mA. These values can be used to specify the power supply needed to ensure the pressure transmitter is powered by a supply voltage that is within its operational limits.
