With model A-10 of WIKA we have added a new generation of pressure transmitters for general industrial applications to our product range. The instrument is impressive not only due to its compact size, but also by its excellent quality and very competitive price.

There is choice of a non-linearity 0.25% or 0.5%. A test certificate is supplied.

The A-10 pressure transmitter is suitable for worldwide use thanks to the international authorisations. All common pressure ranges and process connections are available.
