Heidenhain announced the latest expansion of its gaging line, the Zero-Force Metro Length Gauge. With the uncompromising accuracy that Heidenhain customers have come to expect, extremely sensitive materials can now be measured without fear of product deformation. It is especially suitable for measuring malleable materials in several industries, including medical device, chemical, and precision mechanics.
Two new variants of the established 1Vpp Metro gage are available immediately in 12mm stroke lengths; one with gaging forces of 0.25N in any mounting orientation with a weak spring and one with a gaging force of ~0.0N mounted vertically downward with a Zero-Force spring mechanism. Even with the improvement to the force spec, the Metro still maintains its high accuracy of ±0.2µm and thermal stability due to the optical encoder technology inside.
