PULCOM Σ-D System In-Process measuring heads

» Digital measuring heads

Features

Enhanced waterproofness

Waterproofness was enhanced by unifying the measuring head and the analog cable. Moreover, the analog cable was extended to 3 m, giving it more freedom to decide where to place the relay box.

High precision measuring

The high precision, rigidity and durability proven in the PULCOM Σ -V Series are maintained to make a wide range of high precision measurements possible.

High measuring force

Measurements less affected by the coolant.

Superior linearity throughout measuring range

By applying the best fit method as a correction function, problems such as misalignment or dimensional errors due to changes in the diameter, known to be inherent to measurements with lever type gauges, are automatically corrected, delivering an outstanding linearity.
