Static pressure and
overpressure limits
NOTE: The maximum static
pressure and overpressure for
transmitters with tantalum dia-
phragms (3, C, or G in
nomenclature position 7) is
14,000 kPa (2,000 psi).
The minimum static pressure for all types is 3.4 kPa absolute (14.0 in. H
2
O abso-
lute or 0.5 psia). The maximum static pressure is listed in the following table.
Static pressure effect
on zero and span
These values are for
transmitters with zero
based spans, silicone
oil fill, and Hastelloy
C-276 isolating dia-
phragms at a reference
temperature of 25°C
(77°F).
NOTE: Zero effect can be cal-
ibrated out at line pressure.
The values listed for Type PTSDDA pressure transmitters are for a variation of
1,000 kPa (150 psi) for line pressures between 0 and 2,000 kPa (0 and 300 psi).
The values listed for all other types are for a variation of 7,000 kPa (1,000 psi) for
line pressures between 0 and 14,000 kPa (0 and 2,000 psi).
Ambient temperature
effect on zero and span
These values are for
transmitters with zero
based spans, silicone
oil fill, and Hastelloy
C-276 isolating
diaphragms.
The effects listed are for a variation of ±25°C (±45°F) from a calibration done at a
temperature between -30° and +80°C (-22° and +176°F), as long as the variation
does not take the transmitter out of the temperature specifications listed in
Table
.
