Module de mesure AU

Flexures block gauge "AU" and "DU"


A simple and reliable measurement system

 

AU : With inductive probe

DU : With digital probe

 

Flexure block gauge is ideal for very high volume and high precision applications such as bearing components gauging. It is often the best solution for measuring moving materials, such as roughness testing.

There are no sliding parts to wear out or to cause friction within the frame or sensor whoch makes Metro flexures virtually free from hysteresis.

 

 

 

Flexures can be mounted such that there is little or no stress through the gauge centre line and enabling precision profiling of moving material, such as sheet material or rotating shafts, brake discs etc.

The flexure gauge has forward and reverse spring action with a pneumatically actuated version available for automatic measurements

Zonal repeatability

 

For optimal gauging performance the recommended operation is on centre. The specification is valid when using Metro standard tool holder, tip holder and tip. (Tip used is 6.35 mm TC Ball Tip)

 

- Repeatability on centre : < 0.1µm

- Repeatability off centre : < 0.5µm
