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.
■ Check the compatibility with the medium of the materials subjected to pressure!
■ In order to guarantee the measuring accuracy and long-term stability specified, the
corresponding load limits must be observed.
■ Non-observance can result in serious injury and/or damage to the equipment.
■ Only qualified persons authorised by the plant manager are permitted to install, maintain
and service the pressure gauges.

Mechanical connection
In accordance with the general technical regulations for pressure gauges (e.g. EN 837-2
"Selection and installation recommendations for pressure gauges").
When screwing gauges in, the force
required for this must not be applied through
the case, but rather through the spanner
flats (using a suitable tool) provided for this
purpose on the square shaft of standard
connections.
