Functional Principle, Technical Data
2.1
Short Description
The measuring system consists of a compact controller with display unit, setting keys and connection for sensors of the
CFS series.
Sensors (optical fibers) for the optoCONTROL CLS1000 measuring system can be produced to customer specifications.
In adverse environmental conditions, such as high temperatures, small installation dimensions and poor accessibility in
plants, the optical fibers can be used like an optical micrometer.
The controller consists of a compact transmitting and receiving unit for infrared light with integrated signal evaluation.
The light intensity received via a sensor (optical fiber) is always measured for internal processing.
2.2
Measuring Principle
The controller is designed for adaptable sensors in reflection and transmitted light mode. The controller serves as a
transmitting and receiving unit, as well as for analog signal processing. Digital processing is performed internally on the
software side. Settings can be made and parameters can be read via a user-friendly operation and display field.
In addition, several controllers can be connected in parallel and synchronized. In this context, one controller serves as
master and controls/clocks the other controllers (slaves).
Light is transmitted to the target and back by means of a high-quality optical fiber that works according to 3 different
functional principles, depending on the application:
Two-way system
Reflex mode
Transmission mode
One-way system

2.2.1
Transmission Mode
In transmission mode, the light beam sent out by the transmitter is interrupted by the target to be detected, or is detect-
ed by the receiver. The transmitter and receiver of the one-way light barrier are housed in physically separate fiber-optic
heads. The transmitter (S) beams directly onto the receiver (E). If an object (O) interrupts the light beam, the receiver
voltage falls and the switching function is triggered.
Characteristics:
- Detection of opaque and mirroring targets
- Large ranges and high functional reserves, since the light beam only traverses the signal path once.
- Low susceptibility to failure, therefore well suited for use under difficult conditions, e.g. outdoor applications or those
in dirty environments
- Field of application: Monitoring of production and packaging lines, fill-level measurement in transparent containers, as
well as securing doors and hazard zones.
