5 WIKA Operating instructions pressure gauges Model 700.0X with 851 per ATEX
11025867 02/2005 GB/D/F
GB
3. Technical data and intended use
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
3. Technical data and intended use
Static pressure / Overpressure safety maximum
Model Working pressure Overpressure safe
Pressure ranges max. either side
(static pressure)
Model 700.01:
0 ... 400 mbar to 0 ... 10 bar optionally 100, 250 to maximum
or 400 bar working pressure
Typ 700.02:
0 ... 160 mbar and 0 ... 250 mbar 50 bar 50 bar
0 ... 400 mbar and 0 ... 2.5 bar 100 bar 50 bar
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 2 )
