Product Description

The UniTrans pressure transmitter can be used in level control applications as well as
for pressure measurement applications in process industry. A variety of process con-
nections, measurement ranges, main boards and display options result in a product
for a wide range of applications.

2.1

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 79).

2.1.1

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 trans-
ducers 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
connections can be selected to serve a wide range of applications.

Never exceed the overpressure limit of the respective pressure transducer.
