| Process Indicators: Belt Weighers A comprehensive range of low cost, high performance, digital instruments will bright Red LED displays. They are front panel or field install mount with all configuration done from 4 front panel pushbuttons. They are self-contained, easy-to-use indicators f� digit LED display (-199999 to 199999). Inputs to the instrument include load cell input, encoder input & totalizer reset input. Included is excitation for load cells and a 18 - 24V DC supply for the shaft encoder. The stable bridge excitation output voltage includes sense feedback to compensate for line variations. The precision front end circuitry ensures high stability and accuracy for millivolt input from the load cells in the weigh belt system. Options include analog output for external feed rate control, up to four alarms, pulse output for external totalized weight, RS 232 / RS 485 communications and many others. A feature of this programmable indicator / controller is the calibration method. Pre-calibrated ranges can be allocated zero and full scale values and these can be adjusted on site to allow for deadweight / back-balance offset and single point span calibration (test weight trim). | |
