- This is a very popular choice of indicator for single ingredient batching or proportioning process. Its built in process weighing procedure provides complete single ingredient weighing from two speed feeder control, free fall correction, to discharge of material. This keep PLC programming to minimal and, in simpler applications, completely avoid the need of a PLC. It also vastly reduces the cost and time for system development. The indicator provides 'Gain in weight' and 'Lose in weight' procedures for different needs. User can enter the target weight via the front panel, an external thumbwheels or even through the serial interface (optional RS-232 or RS-485). The process can then be started by triggering a switch and the system will run complete the whole process.
