2.2 Description

These thermometers with inductive contact(s) have been designed

specically for applications in hazardous areas. WIKA manufactures

and qualies these instruments in accordance with the EN 13190 and

DIN 16196 standards.

WIKA operating instructions models TGS55, TGS73 with 831 (Ex)

14327097.02 09/2019 EN/DE/FR/ES

Switch contact model 831

The built-in electrical inductive contacts are non-contact slot-type

inductive proximity sensors, which are powered from isolating ampliers

with certied intrinsically safe circuits. On exceeding the adjustable limit

values, their output circuits are either opened or closed.

2.3 Scope of delivery

Cross-check scope of delivery with delivery note.

Information

... points out useful tips, recommendations and information for

ecient and trouble-free operation.

3.2 Intended use

The instruments serve for temperature measurement in the chemical

and petrochemical industries, oil and gas industries and also for the

energy and shipbuilding industries.Through the high ingress protection

of the thermometer (IP65) and its liquid dampening, operation under

high vibration conditions is possible. In addition they full the high

requirements for resistance against aggressive media.The contact

thermometer, with up to 3 integrated model 831 inductive contacts,

displays the process temperature on-site and opens/closes circuits at

dened temperature values.

The instrument oers many application possibilities for gaseous and

liquid aggressive media that are not highly viscous or crystallising.

Only use the instrument in applications that lie within its technical

performance limits (e.g. temperature limits, 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.

3.3 Improper use

WARNING!

Injuries through improper use

Improper use of the instrument can lead to hazardous

situations and injuries.

▶Refrain from unauthorised modications to the instrument.

▶Do not use the instrument with abrasive or viscous media.

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

improper use.

Do not use this instrument in safety or emergency stop devices.

3.4 Responsibility of the operator

The instrument is used in the industrial sector.The operator is therefore

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 regulations 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 suitable rst-aid equipment is available and aid is provided

whenever required.

■

that the operating personnel are regularly instructed in all topics

regarding work safety, rst aid and environmental protection

and know the operating instructions and, in particular, the safety

instructions contained therein.

■

that the instrument is suitable for the particular application in

accordance with its intended use.

■

that personal protective equipment is available.

3.5 Personnel qualication

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 the

qualications described below.

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 regulations, current standards

and directives, are capable of carrying out the work described and

independently recognising potential hazards.

Special operating conditions require further appropriate knowledge, e.g.

of aggressive media.

3.6 Personal protective equipment

The personal protective equipment is designed to protect the skilled

personnel from hazards that could impair their safety or health during
