About HKM-Messtechnik
HKM-Messtechnik GmbH develops and manufactures force transducers, sensors and force measurement and weighing technology system solutions to customer specification in Freiburg im Breisgau. The company applies strain gauges to metallic measuring bodies, usually as bonded foil strain gauges for individual parts and small series as well as for OEM large-volume series; alternatively, thick-film strain gauges are applied by additive screen printing and thin-film strain gauges by subtractive sputtering. Products include load pins for crane overload protection, strain transducers, wheel load scales for vehicles and aircraft, pedal force gauges, pressure transducers for brake pressure, and closing force gauges. The service portfolio covers consulting, FEM calculation, development, manufacturing and signal processing including integrated or external measuring amplifiers. Around 70 % of the products are exported and used worldwide in machines and systems, including at Otto Bock in the C-Leg prosthetic sensor system. The processes are certified to DIN EN ISO 9001:2015.

Processes and Materials
Foil strain gauges (bonded)
Very precise and flexible application on almost all geometries, suitable for individual parts, small series and OEM large-volume series.
Thick-film strain gauges (screen printing)
Additive screen printing directly onto the measuring body for applications without particular accuracy requirements.
Thin-film strain gauges (sputtering)
Subtractive application of the measuring grids directly onto the measuring body, alternatively for large-volume series production.
Metallic measuring bodies
Base material of the force transducers onto which the strain gauges are applied.
