2. Design and function

2.1 Overview

2.2 Description

With the model 3 test gauge described below, the wetted parts

(process connection and pressure element) are made of stainless steel,

copper alloy or Ni-Fe alloy.The nominal size (NS) of 160 mm [6"] or

250 mm [10"] stated is a rounded value referred to the case diameter.

Case designs in accordance with EN 837

Version “S1”, not shown here, is equipped with a blow-out device in

the case back.

Safety version “S3”, shown above, is equipped with a solid bae

wall between the measuring system and the dial and with a blow-out

back. In the event of a failure, the operator is protected at the front

side, as media or components can only be ejected via the back of

the case.

3. Safety

3.1 Intended use

The instruments described here are suitable:

Models 312.20, 311.11, 342.11: For gaseous and liquid media

that are not highly viscous or crystallising and will not attack

copper alloy or NiFe alloy parts

Models 331.11, 332.1, 33x.30, 33x.50: For gaseous and liquid

aggressive media that are not highly viscous or crystallising, also

in aggressive environments

Models 333.30, 333.50: For high dynamic pressure loads and

vibrations (with case liquid lling)

For pressure measurement with high accuracy

As pressure reference for checking industrial type pressure

gauges

For precision measurement in laboratories

Model 332.11: For mobile precision measurement under particular

safety

Regulations for pressure equipment

Instrument type: Pressure accessory without safety function

Media: Liquid or gaseous, group 1 (hazardous)

Maximum allowable pressure PS, see chapter 3.5 “Labelling /

Safety marking”

Volume of wetted parts: < 0.1 L

The conformity marking CE, UKCA is carried out in accordance

with uid group 1 in accordance with Annex II, Diagram 1 from a

permissible operating pressure > 200 bar

The instrument must only be used with media which are not harmful

to the wetted parts over the entire range of use of the instrument.

A change in the aggregate state or the decomposition of unstable

media is not permitted.

Only use the instrument in applications that lie within its technical

performance limits (e.g. max. ambient temperature, material

compatibility, ...).

3. Safety

14569112.01 08/2023 EN/DE

WIKA operating instructions, test gauge model 3

→ For performance limits, see chapter 9 “Specications”.

In order to achieve an optimal service life of the instru-

ment, it is recommended to load the instrument between

1/3 x PS and 2/3 x PS. See technical information

IN 00.05.

This instrument is not permitted to be used in hazardous areas!

The instrument has been designed and built solely for the intended

use described here, and may only be used accordingly.

The technical specications contained in these operating instructions

and the limit values in accordance with EN 837-1 must be observed.

Improper handling or operation of the instrument outside of its techni-

cal specications and the limit values in accordance with EN 837-1

requires the instrument to be taken out of service immediately and

inspected by an authorised WIKA service engineer.

With instruments which do not correspond to the safety version “S3”,

highly pressurised media might leak out through the possibly burst-

ing window in case of a component failure.

The manufacturer shall not be liable for claims of any type based on

operation contrary to the intended use.

3.2 Improper use

Do not use the instrument within hazardous areas.

Do not use this instrument with abrasive, corrosive and highly

viscous media.

Any use beyond or dierent to the intended use is considered as

improper use.

Unauthorised modications to the instrument are not permissible.

Do not use this instrument in safety or emergency shutdown

devices.

3.3 Responsibility of the operator

The instrument is used in the industrial sector. The operator is there-

fore responsible for legal obligations regarding safety at work.

The safety instructions within these operating instructions, as well as

the safety, accident prevention and environmental protection regula-

tions for the application area must be maintained.

The operator is obliged to maintain the product label in a legible

condition.

To ensure safe working on the instrument, the operating company

must ensure

that the instrument is suitable for the particular application in

accordance with its intended use.

that the requisite personal protective equipment is provided.

On the wetted parts of the instrument, small residual

amounts of the adjustment medium (e.g. compressed

air, water, oil) can adhere from production. With

increased requirements for technical cleanliness, suita-

bility for the application must be checked by the operator

before commissioning.

Liquid media with the property of changing the volume

during solidication can damage the measuring system

(e.g. B. water if the freezing point falls below).
