Typ 700.02:
0 ... 160 mbar and 0 ... 250 mbar
0 ... 400 mbar and 0 ... 2.5 bar
Pressure connection
T
According to the general technical regulations for pressure gauges,
respectively (i.e. EN 837-2 "Selection and installation recommendations for
pressure gauges").
When screw-fitting the gauges the force required for sealing must not be
applied through the case or terminal box but, using a suitable tool, only through
the spanner flats provided for this purpose at the square of the connector.
IP Ingress protection
IP 54 per EN 60 529 / IEC 60 529
Permissible vibratory stress at the mounting location
T
As a matter of principle the instruments should only be mounted at locations
without vibratory stresses
T
Where required, a decoupling from the mounting location can be achieved
e.g. by a flexible connecting line from the measuring point to the pressure
gauge and mounting via a measuring instrument bracket.
T
If this is not possible, the following limits must not be exceeded:
Frequency range < 150 Hz
Acceleration < 0.7 g (7 m/s
