HF Jensen has developed and manufactured sensors since 1972

HF Jensen was founded by Hans Frederik Jensen more than 100 years ago as a machine-tool shop, and is still owned and governed by the same family. Growing out of this mechanical experience, the sensor technology division was started more than 50 years ago by the third generation.

With our 2,000 square meter facility located just north of Copenhagen, HF Jensen develops and manufactures transducers and transmitters for displacement, pressure, differential pressure and level measurements.


Every year, HF Jensen presents its products at trade fairs for sensor systems and measurement technology all over the world. Whether you are looking to find out about new products or seeking advice on ideas and suggestions, our representatives will be there to help.
