Working pressure
Steady: full scale value
Fluctuating: 0.9 x full scale value
Short time: 1.3 x full scale value
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.
Temperature effect
When temperature of the pressure element deviates from reference temperature
(+20 °C): max. ±0.4 %/10 K of true scale value
IP Ingress protection
Enveloping case IP 54 per EN 60 529 / IEC 60 529
(with liquid filling IP 65)
Operating Temperature
Ambient (in Ex-operation):
Model 732.02: -40 ... +60 °C
Model 733.02: -20 ... +60 °C
Medium: The permissible medium temperature does not only depend on the
instrument design, but also on the ignition temperature of the
surrounding gases, vapours or dust. Both aspects have to be
taken into account. For permissible maximum medium
temperatures see table 1.
Attention! With gaseous substances the temperature may increase as a result
of the compression temperature. In such cases the pressure change rate has to
be slowed down resp. the permissible medium temperature has to be reduced.
