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
