September 2000
The Unitrans marks the start of a new era in Wika's pressure measurement instrumentation. The transmitter has a maximum turn down of 1:20, a feature which makes it universally applicable. Its multi-variable display can be rotated 360° with both bargraph and trend permanently displayed.
The case may be adjusted in an upward or lateral direction and is ratatable around its own axis.
Optional extras, such as HART protocol, Profibus PA and IS approval in accordance with ATEX 100a are also available.
