Despription 
The TRILAS TL is an autonomous sensor mounted in a cast aluminum housing containing a visible laser emitter with its power supply and a diode array with focalization optics and a signal processing electronic circuit.

The output of the laser beam as well as the input of the focalization optics are each protected by a protective hood with an air connection. This avoids dust deposit or steam interference. The electrical connection is made via a connector. The sensor is delivered already equipped with the corresponding plug on silicone armored cable (2 m standard length).

Different models of TL are available depending on laser power and measuring range required.
   

Operating principle
The TRILAS TL sensor uses the principle of optical triangulation. A diode array R observes through an optics L the image of the impact A of the emitted laser beam on the measured surface. The distance OA is related to the address N of the lighted diode of the array. The relation, depending only on the geometry of the system, is determined by a factory calibration.
