2.1 Intended use

These pressure gauges are used for measuring pressure and for the switch­ing of switching currents in industrial applications.

GB

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

WARNING!

Risk of injury if qualication is 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 the

qualications described below.

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, current

standards and directives, are capable of carrying out the work described
and independently recognising potential hazards.

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.

2. Safety

■

Pressure gauges must be earthed via the process
connection!

WARNING!

The built-in reed switch does not have its own ignition
source.

It is a 'simple apparatus' in terms of intrinsic safety as dened

in EN 50020.

When powered by a tested and certied intrinsically safe circuit (associated

apparatus), these switches may be used in potentially explosive atmos­pheres up to category 2 without having to take any further measures.

Operating temperatures

Ambient: -40 ... +60 °C

Medium: The permissible medium temperature does not only depend

For permissible maximum medium temperatures see table 1.

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

Observe the information given in the applicable type

examination certicate and the relevant country­specic regulations for installation and use in potentially
explosive atmospheres (e.g. IEC 60079-14, NEC, CEC).

Non-observance can result in serious injury and/or damage
to the equipment.

For additional important safety instructions see chapter
"2.3 Safety instructions for pressure gauges per ATEX"

WARNING!

When installing, commissioning and operating these
instruments, observe the appropriate national safety

regulations (e.g. VDE 0100).

4. Design and function

Description

■

Nominal size 63 mm

■

The instruments measure the pressure by means of resilient bourdon
tube pressure elements

■

The measuring characteristics are in accordance with the EN 837-1
standard

■

In addition, the enclosing and the pressurised components also meet
the requirements of this standard, relating to safety pressure gauges

with a solid bae wall (code S3).

■

When the value exceeds or falls below the set limit, the built-in bistable
reed contact is switched.

Scope of delivery

Cross-check scope of delivery with delivery note.

5. Transport, packaging and storage

5.1 Transport

Check the pressure gauge for any damage that may have been caused by
transport. Obvious damage must be reported immediately.

5. Transport, packaging ... / 2. 6. Commissioning, operation

5.2 Packaging

Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport

(e.g. change in installation site, sending for repair).

5.3 Storage

Permissible conditions at the place of storage:

Storage temperature: -40 ... +70 °C

6. Commissioning, operation

Mechanical connection

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 or the cable terminal box, but rather through the spanner

ats (using a suitable tool) provided for this purpose on the square shaft of

standard connections.

Installation with
open-ended
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).

6. Commissioning, operation

GB

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.

Installation

■

Nominal position per EN 837-1 / 9.6.7, gure 9: 90° ( )

■

Process connection bottom or rear

■

In order to ensure that pressure can be safely and reliably vented
through the case back, a distance of at least 25 mm must be left free
behind the case!

■

In order to avoid any additional heating, the instruments must not be
exposed to direct solar irradiation while in operation!

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:

Frequency range < 150 Hz

Acceleration < 0.5 g (5 m/s

Commissioning

During the commissioning process pressure surges must be avoided at all

costs. Open the shut-o valves slowly.

Switching functions

The switching function of the switches is identied by the indices 1 or 2.

851.1 = NO - normally open, contact makes (clockwise pointer motion)

851.2 = NC - normally closed, contact breaks (clockwise pointer motion)

Electrical load

max. switching voltage: AC/DC 24 V
max. contact rating: 10 W
max. current: 0.5 A

Electrical connection

■

The electrical connection must only be made by qualied skilled

personnel.

■

Cable outlet 1 m length, conductor cross section 0.14 mm2, ying leads

■

The terminal assignment is stated on the connection label of the
pressure gauge

WARNING!

■

The instruments do not provide for incorporated
overcurrent protectors.

If overcurrent protectors are requested, these have to be

provided for externally.

■

The instruments must be connected to the equipotential
bonding of the plant.

Switch point adjustment

The set points of the switch points are freely adjustable over the full scale
range.
The switches are set via the mark pointer on the dial's circumference.
The bayonet ring must be removed in order to adjust the switch point.

Electromagnetic compatibility

Reed switches are electrically passive components, which, when used in

accordance with their intended use, do not aect their surroundings.

8. Maintenance and cleaning / 9. Disposal

8. Maintenance and cleaning

The instruments are maintenance-free.

GB

The indicator and switching function should be checked once or twice every
year. For this the instrument must be disconnected from the process to
check with a pressure testing device.

Repairs must only be carried out by the manufacturer or appropriately

qualied personnel.

Clean the instruments with a moist cloth (soap water).

Prior to cleaning, disconnect the instruments from the mains. Ensure that all
the parts are dry before the power is switched on again.

Residual media in dismounted pressure gauges can result in a risk to

persons, the environment and equipment. Take sucient precautionary

measures.

9. 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.
