Metro Block Gauges makes precision measurements of bores and cavities a simple and reliable process. More
generally, the use of these devices is recommended in applications where space is limited and where the use of axial probes is
not possible.
The family of universal gauges includes 2 mm, 5 mm and 10 mm measurement ranges, the 5 mm unit is used
in most gauging applications and the 10 mm unit is designed for applications requiring a longer range. The 2 mm unit is a
miniaturised version in length, height and thickness and is recommended for applications where space is very restricted.
The block gauges are available in half bridge or digital variants, and offer unrivalled ruggedness, accuracy and
repeatability. All three units are extremely versatile and provide datum surfaces and all the adjustments required for precision
gauging applications.
The Block Gauge pneumatic kit enables automatic
loading of components. Pneumatic actuation
coupled with a spring to control the tip force
ensures repeatable measurement results (fig.1)
The 5 mm and 10 mm block gauges are equipped with an
industry standard tool holder. This ensures that the gauge
is rigid yet easy to adjust. The tip carriers have an M2.5
fitting that accepts all standard tips. Due to its size, the 2
mm gauge has a modified adjustment system that provides
equal rigidity and ease of adjustment (fig.2)
As many Block Gauges as required can
be banked close together. The compact
configuration and the ability to gauge
off the centreline is useful when tightly
packed points need to be measured
(fig.3)
Measurements with offset tip are
possible with all the units, so to
reduce the footprint of the gauge,
adjustment along the frame is
provided (fig.4)
A range of springs is available to
ensure that the Block Gauge can be
used in any attitude. IP65 protection
helps to extend the life of the gauge in
dirty environments (fig.5)

All gauges are supplied configured as spring push. A customer fit pneumatic actuator (code 804570-SX) is required to convert spring
push to pneumatic operation. The Block Gauge is inclusive of integral sensor and additional springs but does not include the pneumatic
actuator, tool holder (4 mm and 6 mm bore), tip carrier (4 mm and 6 mm diameter) or tips.
These must be ordered separately.
