2. Safety

WARNING!

Before installation, commis-

sioning and operation,

ensure that the appropriate

instrument has been selected in terms

of measuring range, design and specic

measuring conditions.

Non-observance

can result in serious injury and/or

damage to equipment.

2.1 Intended use

The Model 52 bimetal thermometer is

mainly used in the process industry

to monitor process temperatures. It is

suitable for installation in pipes and

tanks. The thermometer oers many

application possibilities for temperature

measurement in liquid and gaseous

media.

The instrument has been designed

and built solely for the intended use

described here and may only be used

accordingly.

WARNING!

For hazardous media such

as oxygen, acetylene,

ammable or toxic gases

or liquids, and refrigeration plants,

compressors, etc., in addition to all

standard regulations, the appropriate

existing codes or regulations must also

be followed.

3. Specications

For specications see WIKA data sheet

TM 52.01 and the order documentation.

4. Transport, packaging, storage

4.1 Transport

Check instrument for any damage that

may have been caused by transport.

Obvious damage must be reported

immediately.

4.2 Packaging

Do not remove packaging until just

before mounting. Keep the packaging

as it will provide optimum protection

during transport (e.g. change in instal-

lation site, sending for repair).

4.3 Storage

Permissible conditions at the place

of storage:

Storage temperature: -20 ... 60 °C

Avoid exposure to the following

factors:

■

Direct sunlight or proximity to hot

objects

■

Mechanical vibration, mechanical

shock (shocks during abrupt

positioning)

■

Soot, vapour, dust, corrosive gases

5. Commissioning, operation

When screwing the gauges in, the force

required for this must not be applied

through the case or terminal box, rather

only through the spanner ats provided

for this purpose (using a suitable tool).

Installation with

spanner

Observe the following advice during

sensor installation:

■

If possible, the entire length of the

sensor should be exposed to the

temperature being measured.

■

In pipelines or other measuring

points, the temperature probe must

be positioned as far towards the ow

as possible.

■

When using thermowells, they must

be lled with a thermal contact

medium, in order to reduce the

heat transfer resistance between

the outer wall of the sensor and the

inner wall of the thermowell.

■

The working temperature of the

thermal compound is -40 ... +200 °C.

Before installing the probe, check

whether the probe material used

(specied in the delivery note) is

chemically resistant/neutral to the

medium being measured. This also

applies to thermowells.

6. Maintenance and cleaning

The instrument is maitenance-free.

The indicator should be checked

once or twice every year. For this the

instrument must be disconnected

from the process and checked using a

temperature calibrator.

Clean the instrument with a moist cloth

(soap water).

7. Dismounting, return, disposal

WARNING!

Residual media in

dismounted instruments can

result in a risk to persons,

the environment and equipment. Take

sucient precautionary measures.

7.1 Dismounting

WARNING!

VRisk of burns!

Let the instrument cool

down suciently before

dismounting it! When dismounting it,

there is a risk that dangerously hot

pressure media may escape.

7.2 Return

WARNING!

Absolutely observe when

shipping the instrument:

All instruments delivered

to WIKA must be free from any kind of

hazardous substances (acids, bases,

solutions, etc.).

When returning the instrument, use

the original packaging or a suitable

transport package.

Enclose the completed return form with

the instrument.

The return form is available on the

internet:

www.wika.de / Service / Return

7.3 Disposal

Incorrect disposal can put the environ-

ment 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.
