The integrated silicon measuring cell was developed at the Honeywell research centre in Minneapolis/USA at the end of the 1960s.

Hannes W. Keller, a graduate in physics from the Swiss Federal Institute of Technology (ETH) and named by Honeywell as the inventor, brought the technology to Switzerland in 1971, to the company Kistler, which launched the first piezoresistive pressure transducers with isolated measuring cell on the market in 1973. This was followed in 1974 by the establishment of KELLER AG, a company specialising in pressure measuring technology.

In 2008, more than 1,1 million isolated measuring cells were produced. Of these, 250'000 were delivered to OEMs, 750'000 were used in the production of industrial pressure transmitters, and the rest were distributed among the 500 or so other standard products.
