The RectiRail DL straight edge, developed for checking the geometry of rails, can be used to measure and store the deviations of any mechanical section with respect to a perfect straight line 1 meter long, with an accuracy of +/-50 microns

RectilRail DL consists of 100 dimensional sensors placed on a reference shape. This gauge bears upon the part to be checked, on two skids positioned at its ends.
During the measurement, the electronic circuit reads the output voltage of each sensor and converts this voltage into a distance measurement. Calculated values are then transferred using Bluetooth link to a PDA which display the corresponding curve.
The dimensional sensors used are of the capacitive type (without contact). This efficient technology, which offers great precision, linearity and rapidity, requires that the materials of which the distance from sensor is to be measured be sufficiently conductive: metals, carbon fibre compsites, loaded rubbers, etc.
RectiRail DL functions on oxidised metals and on certain paints, provided that at least one of the steel skids is in good contact with part to be measured.
It also comprises the following elements:
Side stops with indexing
Magnets to hold it on the part to be measured
Navigation in the software via a joystick and 2 buttons
Power supply by six LR6 type 1.5V batteries (or accumulators)
Through its very principle, the capacitive sensor gives an average measurement over and area. Measurement accuracy is guaranteed only for circle with a diameter of 12mm facing the sensor. For measurements on narrow parts, for example 10mm wide, make sure the rule is perfectly centred laterally on the part to be measured and carry out a clibragtion on a reference part.
