75 years of temperature measurement: print advertisements from KROHNE INOR from the 1940s and 2014

KROHNE INOR, the temperature center of excellence within KROHNE, has had major influence on the development of temperature transmitters. Founded 1939 in Malmö, Sweden, KROHNE INOR celebrates its 75th birthday this year.

The company was founded as INOR AB by Austrian Alfred Brakl who emigrated to Sweden in the 1930s. Focussing on temperature assemblies from the beginning, it started as a sales company for temperature assemblies and associated components. In the following years, Brakl expanded by setting up an assembly and matching services for temperature products. Not satisfied with what was available on the market at that time, he decided to develop his own temperature transmitter in the 1960s. From his idea derived a milestone for temperature transmitters: in 1974, INOR introduced the first temperature transmitter that could be built into the connection head. Since then, the design of the head-mounted transmitter has become an industrial standard and helped to extensively promote the name INOR as an innovator.

Progress was also made in the field of temperature assemblies: with temperature assembly starting in the 1950s, it already comprised numerous variants at that time. Since then, the company has gained wide experience in the areas of manufacturing standard and special variants, processing and machining different materials, as well as designs and process connections of industrial temperature assemblies. The quality management of INOR was accredited to EN ISO 9000 already in 1995, since 2002 it is also accredited to EN ISO 14001.

In 2006, KROHNE acquired INOR. Known as a manufacturer of flow and level measuring instruments, the company based in Duisburg, Germany, was looking for an expert company in the field of temperature measurement to offer its customers a broader portfolio from one source. INOR became KROHNE INOR and since then focusses on the extension of the temperature product portfolio and the internationalisation of its business activities. By combining both names the strong brand name INOR was accommodated.

In 2011 the company moved to its current location in Malmö where the urgently required space to enlarge production and assembly lines was available. Today, products and services of KROHNE INOR are available in more than 100 countries worldwide. Examples for the success of the efforts are major orders such as the equipment of the Solana CSP in Arizona, USA, with more than 1,100 measuring points. Among special high-temperature assemblies and accessories, the order comprises 1,148 OPTITEMP TT 51, a SIL2 HART transmitter.
