hazardous areas in industrial applications.

The pressure gauge has been designed and built solely for the
intended use described here, and may only be used accordingly.

The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.

2.2 Personnel qualication

Skilled personnel

Skilled personnel are understood to be personnel who, based on their
technical training, knowledge of measurement and control technology

and on their experience and knowledge of country-specic regulations,

must be observed.
Non-observance can result in serious injury and/or

damage to equipment.
Further important safety instructions can be found in the

individual chapters of these operating instructions.

WARNING!

Risk of injury should qualication be insucient!

Improper handling can result in considerable injury and
damage to equipment.

 The activities described in these operating instructions

may only be carried out by skilled personnel who have

2.3 Safety instructions for pressure gauges per ATEX

WARNING!

Non-observance of these instructions and their contents
may result in the loss of explosion protection.

WARNING!

It is imperative that the application conditions and safety

requirements of the EC-type examination certicate are

followed.

 Pressure gauges must be earthed via the process

connection!

Specications

Permissible temperatures

Ambient: Model 232/262 -40 ... +60 °C

Model 233/263 -20 ... +60 °C (glycerine lling)

-40 ... +60 °C (silicone oil lling)

Medium: The permissible medium temperature not only depends on

the instrument design, but also on the ignition temperature
of the surrounding gases, vapours or dusts. Both aspects
have to be taken into account.
For maximum permissible medium temperatures see table 1.

Attention! In the case of gaseous substances, the temperature may
increase due to compression warming. In these cases it may be neces­sary to throttle the rate of change of pressure or reduce the permissible
medium temperature.

Mechanical connection

GB

In accordance with the general technical regulations for pressure
gauges (e.g. EN 837-2 "Selection and installation recommendations for

pressure gauges").

When screwing gauges in, the force required for this must not be

applied through the case, but rather through the spanner ats (using a
suitable tool) provided for this purpose on the square shaft of standard

connections.

Installation with
spanner

Correct sealing of pressure gauge connections with parallel threads
must be made using suitable sealing rings, sealing washers or WIKA

prole seals. The sealing of tapered threads (e.g. NPT threads) is made

by providing the thread

example, PTFE tape (EN 837-2).

The torque depends on the seal used. Connecting the gauge using
a clamp socket or a union nut is recommended, so that it is easier to

orientate the gauge correctly. When a blow-out device is tted to a

pressure gauge, it must be protected against being blocked by debris
and dirt.
With safety pressure gauges (see dial symbol
space behind the blow-out back is at least 15 mm.

Requirements for the installation point

If the measuring point is not suciently stable a measuring instrument
support such as a bracket or ange should be used for fastening
(possibly via a exible capillary). If vibrations cannot be avoided by
taking suitable measures during installation, liquid-lled instruments

should be used. Instruments must be protected against coarse dirt and

wide uctuations in ambient temperature.

Installation

 Nominal position per EN 837-1 / 9.6.7 Figure 9: 90° ( ⊥ )

 Process connection lower mount (LM) or back mount (BM)

Permissible ambient and operating temperatures

When mounting the pressure gauge it must be ensured that, taking into
consideration the inuence of convection and heat radiation, no devia-

GB

tion above or below the permissible ambient and medium temperatures

can occur. The inuence of temperature on the display accuracy must

be observed.

Permissible vibration load at the installation site

The instruments should always be installed in locations free from
vibration.

If necessary, it is possible to isolate the instrument from the mounting

point by installing a exible connection line between the measuring

point and the pressure gauge and mounting the instrument on a suita­ble bracket.

If this is not possible, the following limit values must not be exceeded:

Dry gauges: Frequency range < 150 Hz

(Model 232/262) Acceleration < 0.7 g (7 m/s

2

)

Liquid-lled gauges: Frequency range < 150 Hz
(Model 233/263) Acceleration < 4 g (40 m/s2)

The liquid lling must be checked on a regular basis.
The liquid level must not drop below 75 % of the gauge diameter.

Commissioning

During the commissioning process pressure surges must be avoided at

all costs. Open the shut-o valves slowly.

7. Maintenance and cleaning

7.1 Maintenance

The instruments are maintenance-free.
The indicator and switching function should be checked once or twice
every year. The gauge must be disconnected from the process to check
with a pressure testing device.

Repairs are only to be carried out by the manufacturer or appropriately
trained skilled personnel.

7.2 Cleaning

CAUTION!

 Clean the pressure gauge with a moist cloth.
 Wash or clean the dismounted pressure gauge before

returning it, in order to protect personnel and the
environment from exposure to residual media.

8. Dismounting and disposal

WARNING!

Residual media in dismounted pressure gauges can
result in a risk to persons, the environment and equip­ment.

Take sucient precautionary measures.

8.1 Dismounting

Only disconnect the pressure gauge once the system has been
depressurised!

When dismounting, close the compensating valve (if available).

8.2 Disposal

Incorrect disposal can put the environment at risk. Dispose of instru­ment components and packaging materials in an environmentally

compatible way and in accordance with the country-specic waste

disposal regulations.
