Process conditions

Process temperature

Depending on maximum permissible temperature of filling
liquid of diaphragm seal and diameter of diaphragm
(see also page 12)
For instruments approved for use in hazardous areas, see
Safety Instructions (XA…), Installation Drawing (CSA) or
Control Drawing (FM).

Pressure specifications
The MWP (maximum working pressure) is specified on the nameplate. The value refers to a reference temperature of
20°C (68°F) or 100°F for ANSI flanges.
– Test pressure (over pressure limit OPL) = MWP (nameplate) x 1.5
– The pressure values permitted at higher temperatures can be found in the following standards:

EN 1092-1: 2001 Tab. 18; ASME B 16.5a – 1998 Tab. 2-2.2 F316; ASME B 16.5a – 1998 Tab. 2.3.8 N10276;
JIS B2201

The maximum pressure for the measuring device is dependent on the lowest-rated element with respect to pressure,
see following sections for this:
– permitted overload of the sensor, page 15, table "Measuring range"
– for process connections "Product structure" and "Dimensions", from page 19 onwards
