12. Control unit BE2
12.1 Introduction
The CT transmitter can be operated using control unit BE2, a desktop or laptop computer in conjunction
with SensorPort software, or via HART
®
Communicator.
In the following, transmitter operation and parameterization using control unit BE2 (normally integrated
into the terminal compartment) are described. The control unit can also be connected to the transmitter
using an intrinsically safe cable that is up to 200 m in length. This allows a point-of-use display to be in-
stalled in a control room so that readings, counter status and settings can be accessed ergonomically.
12.2 Display
Control unit BE2 in the CT has an integrated alphanumeric display with two 16-character lines (format 16
x 60 mm). Measurement data and settings can be read directly from this display.
The LCD display is designed be operated at temperatures ranging from − 20 °C to + 60 °C (-4° F to
140 °F) without incurring any damage. However, at freezing or near-freezing temperatures, the display
becomes slow and readability of the measured values is reduced. At temperatures below − 10 C° (14 °F),
only static values (parameter settings) can be displayed. At temperatures exceeding 60 C° (140 °F), con-
trast decreases substantially on the LCD and the liquid crystals can dry out.
