Figure 4-7. Rosemount 1151
Transmitter Data Flow with
Calibration Options.
This data flow can be summarized in four major steps:
1. Pressure is applied to the sensor.
2. A change in pressure is measured by a change in the sensor output.
3. The sensor signal is conditioned for various parameters.
4. The conditioned signal is converted to an appropriate analog output.
Span Adjustment Range The span on a Rosemount 1151 Analog with E and G output options is
continuously adjustable to allow calibration anywhere between maximum
span and one-sixth of maximum span. For example, the span on a Range 4
transmitter can be adjusted between 25 and 150 inH
2
O (6.2 and 37.2 kPa).
