Values you trust

The company Vision

Cewe to be the leader in precision metering of electricity.

Business idea

“Values you trust” By manufacturing quality products for metering, connected with communicating, processing and presentation of data, we enable our customers to make sensible decisions. This will facilitate energy saving and contribute to a better environment.

Our history

The company founder, Charles Westerberg, began working with electrical equipment back in 1919. His visionary spirit and sensitivity to the needs of the market are still guiding ideals for product development. The company name still reflects the founder’s initials.

Our new products

Electronic products that have their own intelligence and communication features form the corner stones of today’s energy management systems. Our R&D department focuses mainly on electronics and software development. We make it possible for you to gain effective control over your system by using our powerful products for collecting, processing, communicating and presenting measurements.

Our traditional products

Panel meters and transducers are in demand all over the world and are still an important part of our business. Our attention to quality and high degree of customisation mean that we are still one of the most reputed suppliers of these products.
