■ Application
Milltronics BW100 integrator works with single or dual strain
gauge load cell-based belt scales. With a speed sensor, it measures flow rate and totalized weight of bulk solids. It electronically balances the weigh bridge load cells to provide exceptional accuracy. The system is unaffected by uneven lateral loading
so there is no need for load cell matching or mechanical balancing.
The large backlit display features a bar graph comparing current
rate to full scale, reducing the possibility of human error.
The unit has a four-button control pad with tactile feedback keys
used to set all parameters, or you can use Dolphin Plus software
for programming and downloading through a PC or laptop.

Interconnection
All field wiring must have insulation for at least 250 V.
DC terminals shall be supplied from an SELV source in accordance
with IEC 1010-1 Annex H.
For DC versions TB#31 is used for negative (-) and TB#32 is used for
positive (+) connection.
Non-metallic enclosure does not provide grounding between
connections.
Use grounding type bushings and jumpers.
