Description of the modules

The data structure is described from the perspective of the automation system:• Input data: are sent from the device to the automation system• Output data: are sent from the automation system to the device
Analog Input module
Transmission of input variables from the device to the automation system:
Analog Input modules cyclically transmit the selected input variables, including the status,
from the device to the automation system. The input variable is depicted in the first four
bytes in the form of a floating point number as per the IEEE 754 standard. The fifth byte
contains status information pertaining to the input variable. The "Pressure" Analog Input
module in Slot 1 is contained in the pressure PA PROFILE GSD. The other Analog Input
modules can only be used with the manufacturer GSD.

Technical data

Standard device (without diaphragm seal)
Oxygen applications (gaseous)
Oxygen and other gases can react explosively to oils, grease and plastics. The following
precautions must be taken:• All components of the system, such as devices, must be cleaned in accordance with thenational requirements.
• Depending on the materials used, a certain maximum temperature and a maximum
pressure must not be exceeded for oxygen applications.
The cleaning of the device (not accessories) is offered as an optional service.
Devices with measuring cells, nominal value < 10 bar (150 psi)
• pmax: overpressure limit (OPL) of the measuring cell and depending on the processconnection used
• Devices with PVDF threads:• Only mount with the enclosed mounting bracket!
• pmax: 15 bar (225 psi)
• Tmax: 60 °C (140 °F)
Devices with measuring cells, nominal value ≥ 10 bar (150 psi)
• pmax: 40 bar (600 psi)
• Tmax: 60 °C (140 °F)
Thermal shock

Applications with jumps in temperature
Extreme jumps in temperature can result in temporary measuring errors. Temperaturecompensation takes place after a few minutes. Internal temperature compensation isfaster the smaller the jump in temperature and the longer the time interval involved.
For more information: contact the Endress+Hauser sales office.

Process pressure range

Pressure specifications

LWARNING
The maximum pressure for the device depends on the lowest-rated component withregard to pressure (components are: process connection, optional mounted parts oraccessories).
‣ Only operate the device within the specified limits for the components!
‣ MWP (maximum working pressure): The MWP is specified on the nameplate. Thisvalue refers to a reference temperature of +20 °C (+68 °F) and may be applied to thedevice for an unlimited time. Note temperature dependence of MWP. For flanges, referto 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 thetwo materials can be identical.), ASME B 16.5a, JIS B 2220 (the latest version of thestandard applies in each case). MWP data that deviate from this are provided in therelevant sections of the Technical Information.
‣ The overpressure limit is the maximum pressure a device may be subjected to during atest. It is greater than the maximum working pressure by a certain factor. This valuerefers 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 measuring cell range and process connection combinations where theoverpressure limit (OPL) of the process connection is smaller than the nominal value ofthe measuring cell, the device is set at the factory, at the very maximum, to the OPL
value of the process connection. If the entire measuring cell range must be used, selecta process connection with a higher OPL value (1.5 x PN; MWP = PN).
‣ Oxygen applications: do not exceed values for Pmax and Tmax.

Burst pressure
As of the specified burst pressure, the complete destruction of the pressure-bearing parts
and/or a device leak must be expected. It is therefore imperative to avoid such operating
conditions by carefully planning and sizing your facility.
Ultrapure gas applications

Endress+Hauser also offers devices for special applications, such as for ultrapure gas, thatare cleaned of oil and grease. No special restrictions regarding the process conditions apply
to these devices.

Steam applications andsaturated steam
applications

For steam and saturated steam applications: Use a device with a metallic membrane orprovide a water pocket pipe for temperature decoupling when installing.
