The DF3500 Conveyor Scale & Rate Feeder Indicator weighs a continuous load on a running belt to display flow rate and total delivered weight. Scale weight and belt speed readouts may also be selected. A pulse encoder is utilized for variable speed belts. Fixed speed belts use a centrifugal force switch or a pulsed idler switch. The display update rate is automatically determined from the encoder input rate. The flow rate is averaged for a steady display. Two setpoints are provided for each rate and total. Pulse outputs for a mechanical counter with "clear" feature and 4-20mA analog output for flow rate are also available.  ** This product is E.O.L.  Limited quantities and parts available. **
