    Compensating for Span line pressure effects (range 4 and range 5) Rosemount 2051 Range 4 and 5 pressure transmitters require a special calibration procedure when used in differential pressure applications. The purpose of this procedure is to optimize transmitter performance by reducing the effect of static line pressure in these applications. The Rosemount 2051 differential pressure transmitters (ranges 0 through 3) do not require this procedure because optimization occurs at the sensor.
