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.

 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.

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
