Air preparation unit

NB. Air gauging is a measurement of pressure variation.
The variation of pressure must be due to the variation of distance between the gauge
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.
Bowers can supply the air preparation set 55-MBV001
The air supply set delivered from Bowers for the M1/M3 display consist of:
- 1 push in connector for 6mm ext. tubes
- 1 shut off valve
- 1 regulator adjusted at 3 BAR (0.3 MPa) with a 5µm filter
- 1 precision regulator adjusted at 3 BAR (0.3MPa)
- 1 push in connector for 6mm ext. tubes
3.2.

Air pipes

The M1/M3 are fitted with air connectors adapted to connected pipes with 6mm
external diameter and 4mm internal diameter.
In the case of the M3, it is however recommended to use an 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 as an example.
