Pressure Measurement Specification Standard Ranges
The transmitter is available in the
following standard (zero based) ranges or
calibrated to any acceptable intermediate
span specified:-
0-3.75mbar to 0-60mbar differential
(static pressure limit: 32 bar)
0-20mbar to 0-320mbar differential
0-81.25mbar to 0-1.3 bar differential
0-312.5mbar to 0-5 bar differential
0-1.25 bar to 0-20 bar differential
(static pressure limit: 140 bar)

Range Adjustment Span setting:-
The transmitter output can be adjusted to
give a full 4-20mA output change for any
span down to 6.25% of the Upper Range
Limit (URL) e.g. a 320mbar device can be
adjusted down to a minimum span of
20mbar (16:1 down-ranging).

Zero offset:-
The zero (4mA) output of the transmitter
can be set anywhere within the range
-100% to +93.75% of the URL e.g. a
320mbar device can be adjusted to give
4-20mA for -320 to Ombar. At the minimum
span of 20mbar, the same device could also
be calibrated to give 4-20mA for 300 to
320mbar.

Overpressure
The device can withstand overpressure to
the static pressure limit as stated above on
either side without damage to the sensor.

Pressure Containment
Application of pressure beyond the static
pressure limit and up to 350 bar (150 bar for
60mbar unit) may damage the sensor but
process media leakage will not occur.
