About HAEHNE
Since 1977, HAEHNE Elektronische Messgeräte GmbH has been developing, producing and distributing force sensors and evaluation electronics for industrial force and web tension measurement. The family-owned company, headquartered in Erkrath near Düsseldorf, manufactures based on strain gauge (SG) technology products including web tension sensors, tension measuring rollers, measuring rollers, force measuring pins, force measuring bearings, ring force sensors and compression force sensors as well as digital measuring amplifiers. The measuring systems cover force ranges from 10 N to 10 MN and are used in steel and metal processing, plastics and converting, paper and printing, cable and wire manufacturing, textiles, tires, logistics as well as mechanical and plant engineering. In addition to the standard program, HAEHNE offers customer-specific special solutions such as custom dimensions, sensing machine elements, vacuum force sensors (high vacuum down to 10-7 mbar) and explosion-proof sensors according to ATEX. All products are developed, manufactured and distributed entirely in-house at the Erkrath location; sales are conducted through direct sales in the German-speaking region as well as via a global sales network in over 30 countries.
