Analog meters with comparator
Applying |
One of the latest meter model produced by the Company is the electromeasuring meter with
the internal comparator.The meters are designed for the technological control and they are
used in the information boards.
Three types of meters are designed:
1. Single channel meter with one
operation threshold
2. Double channel meter with one
operation threshold per a channel.
3. Single channel meter with two
operation threshold for operation zone controlling.
Divider zone allows to set the operation threshold with the
accuracy of 2% in the range of 1-98% |
