1. Safety instructions

Caution

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").

3. Technical data and use in accordance with intended use

Working pressure

Model 43X.50/30: Steady: full scale value

Fluctuating: 0.9 x full scale value Overpressure safety: see data sheet PM 05.02

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

IP Ingress protection

3. Technical data and use in accordance with intended use

Operating Temperature

Ambient: -20 ... +60 °C

Attention: Footnote 1) under table 1 must be absolutely taken into account!

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 of Permissible 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

)

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.

T Standard version Model 831.XX

PTB 99 ATEX 2219 X (enclosure 2) and ZELM 03 ATEX 0128 X (enclosure 4) Depending on the number of switches and on the case diameter either Model SJ2-N... or Model SJ3.5-...-N... is used.

T Safety pattern version Models 831.XX - SN or - S1N

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.

For further details see WIKA data sheet AC 08.01 or PM 05.02.
