Pressure ranges
Model 700.01:
0 ... 400 mbar to 0 ... 10 bar
Model 700.02:
0 ... 160 mbar and 0 ... 250 mbar 50 bar
0 ... 400 mbar to 0 ... 10 bar
Pressure connection
In accordance with the general technical regulations for pressure gauges
n
(i.e. 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 or terminal box, but rather through the spanner flats (using a suitable
tool) provided for this purpose on the square shaft of standard connections.
IP Ingress protection
IP 54 per EN 60 529 / IEC 60 529
Permissible vibratory stress at the mounting location
Permissible vibration load at the mounting point
n
The instruments should always be installed in locations free from vibration.
n
If necessary, it is possible to isolate the instrument from the mounting point
n
by installing a flexible connection line between the measuring point and the
pressure gauge and mounting the instrument on a suitable bracket.
If this is not possible, the following limit values must not be exceeded:
