2. Design and function

2.1 Description

This instrument is used for the

detection of limit levels in liquids.The

measuring principle is independent

of refractive index, colour, density,

conductivity and dielectric constant.

The switches consist of an infrared LED

and a phototransistor.The light of the

LED is directed into a prism. So long as

the sensor tip of the prism is in the gas

phase, the light is reflected within the

prism to the receiver.When the liquid

in the vessel rises and wets the glass

tip, the infrared lightbeam into the liquid

is interrupted and only a small portion

reaches the receiver.

The optoelectronic sensor OLS-F1 was specifically designed for

sanitary applications and is suitable for a wide range of applications.

Autoclavable applications can be performed up to a temperature of

134 °C.

2.2 Instrument construction

The instruments are fitted with different hygienic process

connections.These contain a glass prism and the electronics

responsible for the evaluation with an O.C. PNP transistor output.

The electrical connection is made via a 4-pin M12 circular connector.

With the connector version, the sensor can be covered with the

included protection cap to enable cleaning in the autoclave at

saturated steam conditions of 134 °C.

3.1 Explanation of symbols

WARNING!

... indicates a potentially dangerous situation that can

result in serious injury or death, if not avoided.

Information

... points out useful tips, recommendations and

information for efficient and trouble-free operation.

3.2 Intended use

The optoelectronic level switches should only be used for level

control or monitoring of liquid media.Their scope of application

is defined by their technical performance limits and materials.

WIKA operating instructions model OLS-F1

Improper use is defined as any application that exceeds the technical

performance limits or is not compatible with the materials. Checking

against improper use is the responsibility of the operator.

■

The liquids must not have any large contamination or coarse

particulates and must not have a tendency to crystallise. Ensure

that the wetted materials of the switch are sufficiently resistant to

the medium being monitored. Not suitable for dispersion, abrasive

liquids, highly viscous media and colours.

■

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

Do not use in zone 1 or 2 hazardous areas.

■

The maximum power and voltage values as specified in the

operating instructions should be adhered to.

■

Do not operate the instruments in the immediate vicinity of strong

electromagnetic fields or in the immediate vicinity of equipment

that can be affected by magnetic fields (min. clearance 1 m).

■

The switches must not be exposed to heavy mechanical strain

(impact, bending, vibration).

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 modifications to the

instrument.

▶

Do not use the instrument within hazardous areas.

Any use beyond or different 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.

To ensure safe working on the instrument, the operating company

must ensure

■

that the operating personnel are regularly instructed in all topics

regarding work safety, first 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.
