Description
With its maximal 1 : 20 turndown ratio the UniTrans can be used in many different applications. This turndown ratio eliminates the necessity of keeping several transmitters in stock; it is much easier to turn down the transmitter instead of changing transmitters (e.g. a 100 bar transmitter can be turned down to 5 bar). As IS - pressure transmitter the
UniTrans can perfectly meet the hardest requirements of industrial pressure measurement. It is approved by the high grade CENELEC certificate complying with the ATEX and CSA approval.
High measuring accuracy
The internal, digital signal processing allows for high measuring accuracy at fast measuring rates and pressure ranges from 20 mbar to 4000 bar.
Multifunctional display
The optional display can be adjusted mechanically and electronically, thus guaranteeing many display variations and an optimal reading from different directions. Bargraph and trend are permanently displayed.
Only a minor modification of the case is required in order to be able to read the display from above. All standard units can be displayed. Two further lines are available for entering additional text (e.g. min./max. values or temperature at the
sensor).
Configuration
With the easy-to-use menu, the user can set parameters such as language, unit, zero poin, span or inverted signal.
The displayed language for transmitters with HART®-
Communication is always English (other languages through configuration software).
The UniTrans also offers the possibility of a tank linearisation with up to 32 holding points.
Power Supply
The UniTrans is fed via intrinsically safe line transformers (e.g WIKA Model KFD2-STC4-Ex1) or via standard barriers with an input power of 12 ... 30 V. The output signal is 4 ... 20 mA, 2-wire system.
