The checkweighing scale is designed for applications in many processes and delivery businesses, since the checkweighing scale supports many interfaces. Furthermore the checkweighing scale features a standard RS-232 interface. In addition the checkweighing scale can be equipped with further interfaces which enable control of the checkweighing scale. For example, the checkweighing scale can be extended with an analogue output 4-10 mA or 0-10 V, or even potential-free contacts. The checkweighing scale is calibrated and thus can be used for tasks in areas of custody transfer. The checkweighing scale can be also integrated into larger rollers, and hence can be used as an extension module.
