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 process spectrometer is used for the in-line analysis of liquids. It is used to detect color

using VIS spectroscopy (VIS = visible). The device can measure and determine color, color

variations or the accuracy of the color in liquids.

Use of the device for any purpose other than that described, poses a threat to the safety of

people and of the entire measuring system and is therefore not permitted.

The manufacturer is not liable for damage caused by improper or non-designated use.

2.3 Occupational 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:

products must be taken out of service and protected against unintentional operation.

LCAUTION

Programs not switched off during maintenance activities.

Risk of injury due to medium or cleaning agent!

‣Quit any programs that are active.

‣Switch to the service mode.

‣If testing the cleaning function while cleaning is in progress, wear protective clothing,

goggles and gloves or take other suitable measures to protect yourself.

2.5 Product safety

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.

 1 Process spectrometer CKI50

1 Measurement gap

2 Process connection

3 Electronics unit

4 Cooling connections for water cooling

5 Measuring head

The process spectrometer can be operated directly in-line without any additional sampling.

All the necessary modules are contained in the electronics unit:

• Power supply

• Light sources

• Spectrometer

Receives the measurement signals, digitalizes them and converts them to a

measurement value.

• Microcontroller

Responsible for controlling internal processes and transmitting data.

• Processor unit

The process spectrometer contains the following light source:

Halogen bulb: 380 to 830 nm

3.2 Measuring principle

The process spectrometer uses optical signals to analyze the medium. Information about

the medium is then output as measurement parameters. The transmitter displays the

measurement parameters. These are used to monitor or directly control a process.

The process spectrometer measures the portion of the sample that is located in the

measurement gap of the measuring head. The sample is illuminated with light and an

interaction takes place between the sample and the introduced light. The transmitted light

is collected again via the observation window and analyzed in the electronics unit. The

spectrum of the collected light is then analyzed and the corresponding measurement

parameter is calculated.

 2 Absorption measurement

1 Light source

2 Optical windows

3 Detector

4 Direction of medium flow

A light source sends a beam of light through the medium via the optical windows. The

incident light beam is measured on the detector side →  2,  9.

3.2.1 Light absorption

The measuring principle is based on the Lambert-Beer law.

There is a linear dependency between the absorption of light and the concentration of the

absorbing substance:

A = -log10 (I/I0) = ε . c . OPL

A Absorption

I Intensity of received light at detector

I0Intensity of transmitted light of light source
