5WIKA Operating instructions pressure gauges Model 700.0X with 851 per ATEX

11025867 02/2005 GB/D/F

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
