Caution
GB
The appropriate national safety regulations (i.e. VDE 0100 /
EN 60 079-14 / EN 837-2) must be observed when installing,
putting into operation and running these instruments.
T Do not work on gauge while under voltage
T Serious injuries and/or damage can occur should the appropriate
regulations not be observed
€T Only appropriately qualified persons should work on these
instruments
2. Description
T The pressure gauges measure the absolute pressure by means of resilient
diaphragm measuring elements. The reference point is absolute pressure
"zero".
T Themeasuring features follow the example of the standards EN 837-3 and
DIN 16 085
The built-in electrical alarm contacts are non-contact slot-type inductive
proximity sensors, which are supplied from control units with circuits that are
certified to be intrinsically safe. When the adjustable set points are reached,
their output circuits will be opened or closed.
T As a standard slot sensors model 831 are used according to EC-type
examination certificate PTB 99 ATEX 2219 X (see enclosure 2) and
ZELM 03 ATEX 0128 X (see enclosure 4)
T SN sensors models 831-SN and -S1N according to PTB 00 ATEX 2049 X
(see enclosure 3) and ZELM 03 ATEX 0128 X (see enclosure 4) are special
designs with safety features (that are not relevant to explosion protection)
for special applications
The connection values of the switches are in accordance with EN 60 947-5-6
("NAMUR").

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.
Installation with
open-end wrench
Temperature effect

When temperature of the pressure element deviates from reference temperature
(+20 °C): max. ±0.8 %/10 K of true scale value

Operating Temperature
Ambient: -20 ... +60 °C
Attention: Footnote 1) under table 1 must be absolutely taken into account!
GB
Medium: 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.
Table 1: Permissible medium temperature (only mechanical part)
Ignition temperature ofPermissible maximum medium temperature
the ambient atmosphere(in the pressure system)
(temperature class)
> 85 °C(T 6)+70 °C
> 100 °C (T 5)+85 °C
> 135 °C (T 4)+100 or +120 °C
> 200 °C (T 3)+100 or +185 °C
> 300 °C (T 2)+100 or +200 °C
> 450 °C (T 1)+100 or +200 °C
1) The permissible uppper ambient temperature for the electrical components is determined by the
electrical connection values and the ignition temperature of the ambient gases, vapours and dusts.
Therefore the maximum permissible ambient temperatures specified in the EC-type examination
certificates for slot-type sensors and SN sensors must be observed as well. The lower of these two
values is to be considered the maximum permissible ambient temperature!
2) The higher values apply only to special versions with higher permissible media temperatures.

Installation
T In order to ensure that with both models 53X.31 ... 34 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!
T In order to avoid any additional heating, the instruments must not be
exposed to direct solar irradiation while in operation!
T With filled versions the ventilating valve at the top of the case must be
opened prior to commissioning!

3. Technical data ... / 4. Alarm contacts
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:
Dry gauges:Frequency range < 150 Hz
(Models 532.XX)Acceleration < 0.7 g (7 m/s
2
)
Liquid-filled gauges:Frequency range < 150 Hz
(Model 533.XX)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. Alarm contacts
The permissible limits for Ui, Ii and Pi of the intrinsically safe supply circuits
depend on the sensor type. They can be taken from the corresponding EC-type
examination certificates. (The sensor type is stated on the connection plate of
the pressure gauge.)

Suitable switch amplifiers are e.g.:
CircuitSensor type Model designationEC-type exami-WIKA-
(s. Ex-certific.)Fa. Pepperl & Fuchsnation certificateModel
EMC according to EN 60 947-5-2.
The instruments are to be protected against strong electromagnetic fields.

The desired value indicators for the alarm contacts are adjustable over the full
range of the instrument. Switching points shall be set in the ranges between
10 % und 90 % of the scale, to ensure switching accuracy and long life of the
mechanical measuring system.

5. Commissioning ... 7. Repairs
5. Commissioning
During the commissioning process pressure peaks must be absolutely avoided.
Open the shut-off valves slowly.
6. Maintenance and servicing / cleaning
The instruments require no maintenance or servicing.
The indicator and switching function 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. For cleaning inside the instrument the mains power supply should be
disconnected by means of the plug box. It must be ensured that all the parts are
dry before the power is switched on again.
7. Repairs
Repairs are to be only carried out by the manufacturer or appropriately trained
personnel.
