3.1 Intended use
The instruments described here are suitable:
Models 312.20, 311.11, 342.11: For gaseous and liquid media
„
that are not highly viscous or crystallising and will not attack
copper alloy or NiFe alloy parts
Models 331.11, 332.1, 33x.30, 33x.50: For gaseous and liquid
„
aggressive media that are not highly viscous or crystallising, also
in aggressive environments
Models 333.30, 333.50: For high dynamic pressure loads and
„
vibrations (with case liquid filling)
For pressure measurement with high accuracy
„
As pressure reference for checking industrial type pressure
„
gauges
For precision measurement in laboratories
„
Model 332.11: For mobile precision measurement under particular
„
safety
Regulations for pressure equipment
Instrument type: Pressure accessory without safety function
„
Media: Liquid or gaseous, group 1 (hazardous)
„
Maximum allowable pressure PS, see chapter 3.6 "Labelling,
„
safety marks"
Volume of wetted parts: < 0.1 L
„
The conformity marking CE, UKCA is carried out in accordance
„
with fluid group 1 in accordance with Annex II, Diagram 1 from a
permissible operating pressure > 200 bar
The instrument must only be used with media which are not harmful
to the wetted parts over the entire range of use of the instrument.
A change in the aggregate state or the decomposition of unstable
media is not permitted.
Only use the instrument in applications that lie within its technical
performance limits (e.g. max. ambient temperature, material
compatibility, ...).
