Detection of errors (holes, breaks) in metal and art off transparencies, broad strips and paper webs, wood veneers etc..
Holes detection ≥1mm
Monitoring width to 2,8
High scanning speed
The GLSL system consists of the two components light transmitters and light receiver. The light-transmitter emitts ray an invisible, modulated infra-red light screen out. The receiver consists of a lining up of receiver modules.
Sensitivity is so adjustable that also smallest holes (≥1mm Ø) can be entered. With the occurrence of a hole the output transistors conduct the relay and the LED " hole detected " light up.
The hole size which can be adjusted with the potentiometer " hole size " to values from ≥ 1mm to approx. ≤ 15mm. With increasing light permeability of the used material the range of adjustment removes the hole size.
non transparent materials: The operating mode " statically " is preferably applied with non transparent materials. The output switches when occurring holes > = the adjusted hole size. An analysis takes place also with deadlock of the material.
Translucent materials: The use of translucent materials in the static operating mode, required for each modification of the light permeability another adjustment of the sensibility, in order to enter same hole sizes.
dynamic material adaption:
Translucent materials: This operating mode is suitable only for translucent materials. The device fits itself translucent materials automatically on thereby can equal large holes with different-translucent Materials (e.g. different types of paper) with the same hole size adjustment to be entered. The permeability of the passing material is measured and stored. This value serves as reference for the adjustment of the sensibility.
With this operating mode it is important that the material which can be tested is in motion. With deadlock takes place no analysis!
Tape rate of
Those max. tape rate depends on the hole size which can be entered. With increasing tape rate sensitivity removes. There is tape rates to approx. 30m/s attainable.
Transmitter: 230V AC (15mA-35mA) Receiver 24V DC (50-200mA)
Source of light:
GaAlAs, infrared, 36 kHz
-10 °C to 50 °C
NPN/PNP max. 100mA short circuit proof, delay time approx. 1ms optionally: Relay, 5A / 250V, ind. free, 0,2s switch-off delay, delay time approx. 10ms
IP 54; (optionally IP65)
The standard execution is equipped with transistor outputs (PNP and NPN). When desired a relay output is available. Delay time at the transistor outputs is approx. 1ms. With the relay output is built in a switch-off delay of approx. 200ms.
Adjustable mounting options and t-slot grooves on the rear side of the device enable a flexible mounting. The housings are flat mounted in the distance from approx. 50-100mm. The material tape which can be tested should be for instance in the center between transmitter and receivers. The tape must cover the total width of the controllfield. An overlap of approx. 15mm is to be observed. With narrower tapes the free sections of the receiver are to be covered.
The connection is made by 6pol. Plug-in connections. When mounting the GLSL take care, that both housing pups are not torresed
