WARNING
The maximum pressure for the device depends on the lowest-rated component with
regard to pressure (components are: process connection, optional mounted parts or
accessories).
‣
Only operate the device within the specified limits for the components!
‣
MWP (maximum working pressure): The MWP is specified on the nameplate. This
value is based on a reference temperature of +20 °C (+68 °F) and may be applied to the
device for an unlimited period of time. Note temperature dependence of MWP. For
flanges, refer to the following standards for the permitted pressure values at higher
temperatures: EN 1092-1 (with regard to their stability/temperature property, the
materials 1.4435 and 1.4404 are grouped together under EN 1092-1; the chemical
composition of the two materials can be identical.), ASME B 16.5a, JIS B 2220 (the
latest version of the standard applies in each case). MWP data that deviate from this
are provided in the relevant sections of the Technical Information.
‣
The overpressure limit corresponds to the overpressure limit OPL of the entire device.
This value refers to a reference temperature of +20 °C (+68 °F).
‣
The Pressure Equipment Directive (2014/68/EU) uses the abbreviation "PS". The
abbreviation "PS" corresponds to the MWP (maximum working pressure) of the device.
‣
In the case of sensor range and process connection combinations where the
overpressure limit (OPL) of the process connection is smaller than the nominal value of
the sensor, the device is set at the factory, at the very maximum, to the OPL value of
the process connection. If the entire sensor range must be used, select a process
connection with a higher OPL value (1.5 x PN; MWP = PN).
‣
Oxygen applications: do not exceed values for P
max
and T
max
.

Ultrapure gas applications
Hauser also offers devices for special applications, such as for ultrapure gas, that
are cleaned of oil and grease. No special restrictions regarding the process conditions apply
to these devices.
Steam applications and
saturated steam
applications
For steam and saturated steam applications: Use a device with a metal process membrane
or provide a water pocket pipe for temperature decoupling when installing.
Thermal insulation
Thermal insulation with diaphragm seal directly mounted
The device may only be insulated up to a certain height. The maximum permitted
insulation height is indicated on the device and applies to an insulation material with a
heat conductivity ≤ 0.04 W/(m x K) and to the maximum permitted ambient and process
