B&C Electronics BC 6587 Universal controller – transmitter
The BC 6587 and BC 7687 controllers are used when it
is necessary to add to any transmitter the display, control,
alarm and the automatic sensor cleaning functions.
The 0-20 mA or 4-20 mA signal from the transmitter is sent
to the instruments who perform the above functions.
In some cases, it is necessary to measure the value before
and after the process. BC 6587 and BC 7687 are able to
display and control the difference of the measurements of
the two transmitters operating with the same full scale.
