5 Product Description
The intrinsically safe pressure transmitter UniTrans can be used in level control
applications as well as for pressure measurement applications in process industry.
A variety of process connections, measurement ranges, main boards and display
options result in a product for a wide range of applications.
5.1 Construction
The UniTrans consists of a pressure sensor, a control interface unit and a housing
cover with optional display. Due to this modular design, different transmitter versions
can be mounted (see “Model Key” on page 151).
5.1.1 Pressure Transducer
The pressure transducer has a piezo-resistive or thinfilm measurement cell depend-
ing on the pressure range. The sensors are temperature compensated, and have a
hermetically welded membrane which is "helium" leak-tested. The pressure transduc-
ers do not have internal sealing elements.
Pressure transducers further distinguish themselves from one another based on their
pressure ranges and the different materials of wetted parts. Different process connec-
tions can be selected to serve a wide range of applications.
Never exceed the overpressure limit of the respective pressure transducer.
