Weighing indicator

Weighing indicator BST100-B11 is mainly used for weighing, feeding&batching systems of belt scale. It adopts A/D conversion technology and broad-range speed pulse input circuit. Max. 8 loadcells are connectable. The functions of segmenting calibration, zero auto- tracking, key-locking & auto-locking, full digital setting & calibration, system start&stop control, feeding closed-loop control and so on are available. It can support industry configuration software.
