    Reference Manual 00809-0100-4235, Rev BA Rosemount 1152 April 2007 NOTE On Range Codes 6, 7, 8, 9, and 10, the span adjustment has a significant effect on zero. This effect becomes increasingly more pronounced as span is decreased. The span effect on zero is great enough in some instances to cause a decrease in full-scale output with an increase in span.

    Reference Manual 00809-0100-4235, Rev BA Rosemount 1152 April 2007 Zero Zero shift with static pressure is not systematic. However, if the calibrated range includes zero differential pressure, the effect can be trimmed out after installation and with the unit at operating pressure. Equalize pressure to both process connections and turn the zero adjustment until the ideal output at zero differential input is observed.

    The block diagram in Figure 4-1 on page 4-3 illustrates the operation of the transmitter. Rosemount 1152 Alphaline Pressure Transmitters have a variable capacitance sensing element, the -Cell (see Figure 4-2 on page 4-4). Differential capacitance between the sensing diaphragm and the capacitor plates is converted electronically to a 2-wire, 4–20 or 10–50 mA dc signal.
