TECHNICAL DATA

2.1 Pressure Ranges

The transmitter is supplied in one of the standard (zero based) ranges or it can
be calibrated to any acceptable intermediate span. Refer to Table 1-1.
The transmitter label shows the factory calibrated range and the maximum
working pressure (MWP). The upper range limit (URL) = MWP.

Figure 2-1 shows the limits for range adjustment. For example:
Span: The minimum span available for a 2 bar device is 0.02 bar (100:1
down-ranging).
Zero offset: A 2 bar (MWP) gauge device can give 4 to 20 mA in the range
-1 bar to 2 bar. For example: If the span is 0.02 bar, 4 to 20 mA is available
anywhere in the range up to a maximum zero offset of 1.98 bar (calibrated
range = 1.98 to 2 bar).
Minimum span
Lower range value (LRV) = 4 mA pressure value
Upper range value (URV) = 20 mA pressure value
