Air Preparation Unit - Air Pipes - sylvac D70A Manuel D'utilisation

3. Air preparation unit - Air Pipes

3.1 Air preparation unit
Air gaging is a measurement of pressure variation.
The variation of pressure must be due to the variation of distance between the gage
and the part being measured. Therefore it is mandatory to have a high stability air
input, in order not to have variation of pressure due to air input variation.
Sylvac can supply the air preparation set REF : 804.2203
The air supply set delivered from Sylvac for the D70A display
consists of :
- 1 push in connector for 8mm ext. tubes
- 1 shut off valve
- 1 regulator adjusted at 3 BAR (0.3 MPa) with a 5μm filter
- 1 precision regulator adjusted at 2 BAR (0.2MPa)
- 1 push in connector for 8mm ext. tubes
3.2 Air pipes
The D70A are fitted with air connectors adapted to connected pipes with 6mm external diameter
and 4mm internal diameter.
In the case of the D70A with 2 inputs (804.2075), it is however recommend to use a 8mm ext.
tube from the output of the air preparation unit to a Y connection/reduction to 6mm to the display.
We recommend to use flexible pipes that prevent risk of fall or tilt over of the display due to the
orientation of the pipes. See the following picture.
