The dimensions in brackets apply to housings with a raised cover (for optional display). Dimensions written in
italics apply to devices with an aluminum housing.
Oxygen applications Oxygen and other gases can react explosively to oils, grease and plastics, such that, among other things, the
following precautions must be taken:
– All components of the system, such as measuring devices, must be cleaned in accordance with BAM
requirements (DIN 19247). (BAM = Federal Institute for Materials Research and Testing).
– Depending on the materials used, a certain maximum temperature and a maximum pressure must not be
exceeded in oxygen applications. The maximum temperature T
max
for oxygen applications is 60°C (+140°F).
The devices suitable for gaseous oxygen applications are listed in the following table, indicated by p
max
.
PWIS-free applications Special cleaning of transmitter to remove paint-wetting impairment substances e.g. for use in paint shops

see Page 67 ff "Ordering information", feature 80 "Sensor seal".
Ultrapure gas applications Hauser also provides devices which have been cleaned of oil and grease for special applications, such
as ultrapure gas. No special restrictions regarding the process conditions apply to these devices.
