<p align="JUSTIFY">A long stroke displacement sensor. The D90 sensor comprises an incremental rotating encoder driven by a serrated belt and kept taut by a spiral spring. The D90 is available in two versions: 7 and 15m.</p>
<h3><img src="http://www.jeanlutzsa.fr/DNN/Portals/0/rsx/F89.png" alt="" width="120" height="120" align="left" hspace="10" />F82</h3>
<p align="JUSTIFY">A linear displacement sensor for measuring depth. The F89 uses the principle of the pulley that travels without sliding along a cable stretched between the two ends to be measured. The measurement signal is delivered by an incremental rotary encoder (C82).</p>
<h3><img src="http://www.jeanlutzsa.fr/DNN/Portals/0/rsx/P80.png" alt="" width="120" height="140" align="left" hspace="10" />P82</h3>
<p align="JUSTIFY">The P82 sensor uses the follower wheel that travels over the surface whose displacement needs to be measured. The wheel’s spindle forms an integral part of the incremental rotary encoder (C82). The wheel/encoder assembly is mounted on the end of an adjustable length rocker arm. The rocker arm spindle is mounted on a rubber ring that can be prestressed in order to develop a bearing force of several deca Newtons.</p>

<p align="JUSTIFY">The VR28 sensor is a proximity sensor specially designed for working in the adverse conditions encountered in public works.
It consists of a metal tube and a cable fed out through a gland box: The detection element creates a high frequency electromagnetic field at the tip of the sensor and its amplitude is dampened by the presence of a nearby metal mass.</p>
