CCD Array Sensor TSP

Typical applications 

Edge position control	Centreline measurement	Loop control

 General Description

The sensor TSP consists of a lens, a silicon photodiode array and a processing electronics.

The image of the scanned area is projected onto the diode array by the lens. The information from the diode array is processed by a microprocessor which converts the position or size of different dark or luminous areas to an analogue output 0-10 V.

Features

The diode array sensor TSP has been designed for heavy industry, with:

• Adjustable mounting stand (2 axis). In case the sensor must be replaced, it can be easily dismounted from the stand, without disturbing the alignment.
• Protective hood
• Control panel behind a hinged cover, including :
  • Control LED (P.P.); On when a product is detected.
  • Saturation LED (Sat); On when the diode array is saturated.
  • Exposure-time switch (tm, t, at); sets the exposure time. The exposure time is chosen to avoid saturation of the array. The position "at" (automatic) of the switch allows on some models an automatic control of the exposure time in relation to the level of illumination on the array.
  • Sensitivity potentiometer (sens).
  • Jack socket carrying the diode array signal for display on an oscilloscope (Vid).
  • Test push button allowing simulation of a presence of light (Test).
