Sartorius EWM 609 Weighing Electronic Unit


The EWM 609 weighing electronics unit, serving in combination with a Sartorius weigh-bridge, constitutes a belt weigher that is used in its standard application for high-precision monitoring of conveyed quantities and flow rates. The weighing electronics unit is user-oriented. Production data, including their absolute and proportional (%) dimensional units, appear at the touch of a button. Function keys are provided for such operations as zeroing and measuring accuracy checks (by means of calibrating weights), and an array of menu keys and plaintext displays guide the user self-explanatorily through the various modes of operation and dialogues. The setup procedure can easily be executed by the user, as it involves nothing more than automatic calibration via interactive dialogue between the weigher and its operator. All weighing-process interferences are logged in the fault memory, along with their dates and times of occurrence, optically signaled via status LED and at the error signal output, indicated in plain text at the touch of a key, and documented in a fault report (optional).
