Special features Explosion protection EEx ia IIC T6 acc. to ATEX and CSA For the use in hazardous environments: gases and mists: zone 1, zone 2 and connection to zone 0 dust: zone 21, zone 22 and connection to zone 20 High measuring accuracy Scaleable measuring ranges via Turn down of up to 1:20 Configuration via DTM (Device Type Manager) according to the FDT (Field Device Tool) - concept (e.g. PACTware) oder SIMATIC PDM Fully welded, stainless steel diaphragm
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.
