Caution
1. Safety instructions
The appropriate national safety regulations (i.e. EN 837-2 Selection
and installation recommendations for pressure gauges) must be
observed when installing, putting into operation and running these
instruments.
TSerious injuries and/or damage can occur should the appropriate
regulations not be observed
TOnly appropriately qualified persons should work on these
instruments
TThe actual maximum surface temperature is not generated by
the instruments themselves, but primarily by the respective
medium temperature! For permissible maximum medium
temperatures see table 1.
1. Safety instructions / 2. Description
2. Description
TNominal size 100
TThe pressure gauges measure the pressure by means of resilient diaphragm
measuring elements. Via the subtracting movement the difference in pressure
is directly indicated as pressure differential (optionally also available as
"duplex pressure gauge" with 2 pointers).
TThe measuring features are in accordance with the standards EN 837-1

3. Technical data and use in accordance with intended use
Working pressure
Steady: full scale value
Fluctuating: 0.9 x full scale value
Short time: 1.3 x full scale value
Pressure connection
TAccording 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.

Materials
Wetted parts: Stainless steel 1.4571 / 1.4404
Movement: Stainless steel
Dial and pointer: Aluminium
Case, bezel ring : Stainless steel
Window: Laminated safety glass
Installation
TNominal position per EN 837-1 / 9.6.7 Figure 7: 90° ( )
TPressure connections: lower mount (LM) parallel in-line (with special versions
back mount)
TIn order to ensure that pressure can be safely and reliably vented through the
case back, a distance of at least 25 mm has to remain free behind the case!
TIn order to avoid any additional heating, the instruments must not be
exposed to direct solar irradiation while in operation!
TWith filled versions the ventilating valve at the top of the case must be
opened prior to commissioning!

Permissible vibratory stress at the mounting location
TAs a matter of principle the instruments should only be mounted at locations
without vibratory stresses
TWhere 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.
TIf this is not possible, the following limits must not be exceeded:
Dry gauges: Frequency range < 150 Hz
(Model 732) Acceleration < 0.7 g (7 m/s2)
Liquid-filled gauges: Frequency range < 150 Hz
(Model 733) Acceleration < 4 g (40 m/s2)
The liquid filling has to be checked on a regular basis.
The liquid level must not drop below 75% of the gauge diameter.
4. Commissioning
During the commissioning process pressure peaks must be absolutely avoided.
Open the shut-off valves slowly.
5. Maintenance and servicing / cleaning
The instruments require no maintenance or servicing.
The indicator should be checked once or twice every 12 months.
The instrument must be disconnected from the process to check with a
pressure testing device.
The instruments should be cleaned with a damp cloth moistened with soap
solution.
6. Repairs
Repairs are to be only carried out by the manufacturer or appropriately trained
personnel.
