1. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate
pressure gauge has been selected in terms of measuring range, design and
specific measuring conditions.
„ The compatibility of the materials under pressure with the medium must be checked!
„ In order to guarantee the measuring accuracy and long-term stability specified, the
corresponding load limits must be observed.
„ Serious injuries and/or damage can occur should these not be observed.
„ Only qualified persons authorised by the plant manager are permitted to install,
maintain and service the pressure gauges.
