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 ...
At 0% level, the pressure at the transmitter is 1.10*(500 +200 mm), or 770 mmWC. At 100% level, the pressure at the transmitter is 1.10*(500+1000 mm) or 1650 mmWC. Therefore, the transmitter should be calibrated 770 to 1650 mmWC to measure liquid levels of 200 mm to 1000 mm above the nozzle.
