2 Basic safety instructions

2.1 Requirements of the personnel

• Installation, commissioning, operation and maintenance of the measuring system may be

carried out only by specially trained technical personnel.

• The technical personnel must be authorized by the plant operator to carry out the specified

activities.

• The electrical connection may be performed only by an electrical technician.

• The technical personnel must have read and understood these Operating Instructions and

must follow the instructions contained therein.

• Faults at the measuring point may only be rectified by authorized and specially trained

personnel.

Repairs not described in the Operating Instructions provided must be carried out only

directly at the manufacturer's site or by the service organization.

2.2 Intended use

The scattered light turbidity sensor is used to measure undissolved solids, emulsions and

immiscible media in process liquids. The sensor is suitable for use in a wide range of

applicationsin a variety of industrial sectors , such as:

• Outgoing goods inspection/purity monitoring

• Filter control

• Condensate regulation

• Turbidity measurement in

• Breweries

• Drinking water

• Brine

• Leak detection in heat exchanger

Any use other than that intended puts the safety of people and the measuring system at risk.

Therefore, any other use is not permitted.

The manufacturer is not liable for harm caused by improper or unintended use.

2.3 Workplace safety

As the user, you are responsible for complying with the following safety conditions:

• Installation guidelines

• Local standards and regulations

• Regulations for explosion protection

Electromagnetic compatibility

• The product has been tested for electromagnetic compatibility in accordance with the

applicable international standards for industrial applications.

• The electromagnetic compatibility indicated applies only to a product that has been

connected in accordance with these Operating Instructions.

2.4 Operational safety

Before commissioning the entire measuring point:

1. Verify that all connections are correct.

2. Ensure that electrical cables and hose connections are undamaged.

3. Do not operate damaged products, and protect them against unintentional operation.

4. Label damaged products as defective.

During operation:

‣If faults cannot be rectified,

take products out of service and protect them against unintentional operation.

2.5 Product security

2.5.1 State of the art

The product is designed to meet state-of-the-art safety requirements, has been tested, and

left the factory in a condition in which it is safe to operate. The relevant regulations and

international standards have been observed.

3.2 Measuring principle

Turbidity

Turbidity refers to the appearance of a liquid that contains suspended particles. The presence

of these particles causes the light to be scattered and absorbed, giving the liquid a turbid, or

cloudy, appearance. The amount of light scattered or absorbed in a liquid can be used in a

measuring system to determine the degree of turbidity.

Scattered light method

A focused parallel beam of light is passed through the medium. This beam is known as the

transmitted light and is measured by a transmitted light detector. If the medium does not

contain any particles, the transmitted light detector detects all the light transmitted by the

light source.

If there are particles in the medium, the light is scattered in all directions, but primarily in a

forward direction. The optical system is designed such that the scattered light is measured at

an angle of 11°. This angle of measurement ensures that the maximum scattering signal

present is detected at the scattered light detector.
