2. Design and function
2.1 Description
The switch contacts permanently installed in the pressure gauge close or open
at set limit values, depending on the switching function. Switching functions are:
Normally closed, normally open, change-over contact.
Instruments with switch contact model 821
Model 821 magnetic snap-action contacts are auxiliary current switches which
open or close connected electric circuits via a contact arm which is moved by the
instrument pointer.
Instruments with switch contact model 851
Model 851 reed contacts are auxiliary current switches which open or close con-
nected electric circuits at the set limit values via a permanent magnet which is
moved by the instrument pointer.The reed contacts used are bistable switches,
which keep their condition after a signal change up to the next actuation.
Instruments with switch contact model 830 E
Theinductivecontactwithintegratedmodel830Eswitchingampliercanswitch
small loads directly. This is, for example, the case with applications with program-
mable logic controllers (PLCs).
The advantages of inductive contacts are the particularly fail-safe contact opera-
tion,nowearduetoproximitycontactoperationaswellasvirtuallynoeectonthe
measuring system.
No additional control unit is required.
The electronic contact is a 2- or 3-wire design with PNP output.

3.1 Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can result in seri-
ous injury or death, if not avoided.
WARNING!
... indicates a potentially dangerous situation that can result in burns,
caused by hot surfaces or liquids, if not avoided.
Information
... points out useful tips, recommendations and information for ef-
cientandtrouble-freeoperation.
3.2 Intended use
Wherever the process pressure has to be indicated locally and, at the same time,
circuitsneedtobeswitched,theswitchGAUGEndsitsuse.
These instruments are used to control process values, to monitor plants and to
switch circuits in industrial applications.
This instrument is not permitted to be used in hazardous areas!
Only use the instrument in applications that lie within its technical performance
limits (e.g. max. ambient temperature, material compatibility, ...).
→Forperformancelimitsseechapter9“Specications”.
The instrument 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.

described below.
3.5 Skilled personnel
Skilled personnel, authorised by the operator, 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regula-
tions, current standards and directives, are capable of carrying out the work
described and independently recognising potential hazards.
3.6 Special hazards
WARNING!
Forhazardousmediasuchasoxygen,acetylene,ammableortoxic
gases or liquids, and refrigeration plants, compressors, etc., in ad-
dition to all standard regulations, the appropriate existing codes or
regulations must also be followed.
WARNING!
Residual media in dismounted measuring instruments can result in a
risk to persons, the environment and equipment.
Takesucientprecautionarymeasures.

4. Transport, packaging and storage
4. Transport, packaging and storage
4.1 Transport
Check the instrument for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to property can
occur.
▶ When unloading packed goods upon delivery as well as during
internal transport, proceed carefully and observe the symbols on
the packaging.
▶ With internal transport, observe the instructions in chapter 4.2
“Packagingandstorage”.
4.2 Packaging and storage
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).
4.3 Storage
Permissible conditions at the place of storage
Storage temperature: -20 ... +70 °C
Humidity:≤80%relativehumidity(nocondensation)
Avoid exposure to the following factors:
■
Direct sunlight or proximity to hot objects
■

5. Commissioning, operation
5.1 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 the instruments in, the force required for sealing must not be
appliedthroughthecase,butonlythroughthespanneratsprovidedforthis
purpose, and using a suitable tool.
Forparallelthreads,useatgaskets,lens-typesealingringsorWIKAprole
sealings at the sealing face .With tapered threads (e.g. NPT threads), sealing is
made in the threads , using a suitable sealing material (EN 837-2).
The torque depends on the sealing used. In order to orientate the measuring
instrument so that it can be read as well as possible, a connection with clamp
socketorunionnutshouldbeused.Whenablow-outdeviceisttedtoaninstru-
ment, it must be protected against being blocked by debris and dirt.
