Robustness.
New industry design to be used for applications even under the harshest
of ambient conditions: Stratos® Pro. Fully encapsulated and protected in
shatterproof and corrosion-resistant plastic enclosure with outdoor
approval rating.
Tough
The reinforced and UV-resistant plastic enclosure of the Stratos® Pro
supports the product functionality. There are neither prominent control
elements nor those with a high mechanical load to be found on the
vrtually plane, dirtproof front panel. Injection molded, directly sealed
keys are made from high-quality EPDM so that it is no longer necessary to
stick films, which had to perform a sealing function, onto the front of
the device. The high IP 67 rating is maintained under all conditions
reliable and safe operation is guaranteed in the range from 20 °C to
+65°C, even for operation in hazardous locations.
All-round resilience
The display window of the Stratos® Pro is connected directly to the
plastic enclosure during the innovative molding process. It is made from
reinforced safety glass, is scratch-resistant and UV resistant. All the
device's electronics are completely encapsulated in the door module:
there are no exposed PCBs. The large rear unit can be mounted separately.
All electrical connections are made by means of screw terminals in the
door unit, so that if the door module is replaced, the complete cable
guide can be retained in the rear unit.
All the electronics in a Stratos® Pro are encapsulated in the door module
of the device. Exchangeable modules for different process parameters.

FieldComm Group (FCG) makes available to its members and to the public certain device driver (DD) files, in various forms, that have passed certain tests conducted by or through FCG. The DD files are, or are created from, submissions to FCG by FCG members and are provided by FCG AS IS. FCG disclaims all liability for the accuracy, suitability or use of the DD files. Each member creating DD files has its own policies regarding supporting use of those files, and may, for instance support use of DD object code files, but not DeviceInfo or other files. While FCG is under no obligation to provide support for use of any DD files, FCG welcomes all inquiries on the subject and will often be able to assist.
