About Sentech AS

Sentech AS was established in 1995, with headquarters and manufacturing in Oslo, Norway.

In its early days, the company developed and patented the SeCaP Single Electrode Capacitance sensor technology, in close cooperation with the SINTEF research center in Trondheim and Norsk Hydro Research Centre in Porsgrunn (now operated by Equinor).

This SeCaP sensor now forms the core of a range of products that provide highly accurate, stable and versatile measurement solutions for the oil and gas and subsea production markets.


Our history

How it all began

In the early nineties, a small leisure boat fitted with a diesel engine crashed into a ponton because the engine stopped at the very moment the skipper put the gear in reverse. The crash caused limited but very annoying damages to the front section of the boat. When investigating the incident the skipper found that the engine had stopped because of water in the fuel system. The skipper asked his good friend and colleague Bjørn Engebretsen to come up with an alarm system to warn him if and when water was to re-enter into the fuel system.

Bjørn came back to the skipper with a single, small sensor that was mounted into the fuel filter. The sensor sounded an acoustic alarm when water was detected in the fuel.

Sentech AS backtracks its unique, patented SeCaP sensor technology to that incident, although the product portfolio today has little to do with the alarm system for the unfortunate skipper.

Cooperation with research centers

In the early years after the company was established in 1995, Sentech AS cooperated with Norwegian research center SINTEF, and throughout its history, most of our products have been developed and tested in close co-operation with Norsk Hydro Reaserch Centre in Porsgrunn, Norway (now one of Equinor’s seven global research centers).

Acquisitions and change of ownership

In June 2010, Sentech AS was acquired by Advantec Group, and the company name was changed to Advantec Sensing AS.

When GE Oil & Gas acquired Advantec AS in October 2015, Advantec Sensing AS was excluded from the transaction and the company regained its original name of Sentech AS. The majority of shares today is held by Norvestor Equity.
