2.2  Instrument base

 

The base is chemically nickel-plated in order to make it very resistant to corrosion. Its lower 
face, which has been machined to ensure that is rigorously flat, includes three finely-machined 
support lugs (air bearings) that guarantee the stability of the height gauge. 
 

 

 
 

 

These  lugs  form  a  large  surface  so  that  any  grooves  or  other  similar 
irregularities on the granite table can be easily cleared. 
 

 
The faces (9) defined by the red zones in the schema below are specially designed to support 
the instrument against a parallel gauge block or for guiding it along such a block. 
 

 

 

 

 

 

 

 

2.3  Air cushion 

The air cushion, which is generated by an integrated electric pump, allows the height gauge to 
be easily moved on the granite table. The height gauge can then be moved effortlessly and 
any wear created by friction is avoided.
