KELLER is Europe's largest manufacturer of isolated piezoresistive
pressure sensors and pressure transmitters. KELLER are a world leader
in pressure sensing technology continually developing new materials and
manufacturing processes, that is why this company remain successful.
This Company introduces a comprehensive range of products, from
simple Pressure Capsules, to fully compensated digital pressure
transmitters, also low-cost industrial pressure transmitters, digital
pressure gauges, recording digital manometers. Modern advanced
production techniques enable KELLER to offer competitive pricing for
medium and high volume production orders. Customer engineered special
products are easily accommodated.
KELLER supply Pressure Sensors to all industries and applications
and are specialist in the following areas: Refrigeration, Oil & Gas
'down-hole', Water Depth, Hydraulics, Autoclave Sterilisers,
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.
