The AND Weighing AD-4323 is a compact, high performance digital weighing indicator which offers sophisticated and flexible functions at an exceptional value. It boasts an extensive range of standard and user selctable features for a wide variety of industrial weighing applications.
High speed A/D converter- up to 70 times per second
1/10,000 Division Display Resolution - a high 1/96,000 count internal resolution and a 1/10,000 display resolution delivers precision for the most demanding appplications
Multi-Function Comparator - the built in comparator turns the AD-4323 indicator into a self-contained weighing controller. Five different comparator modes are available ensuring complete flexibility in custom weighing system configuration
Drives up to 8 Load Cells - load cell excitation voltage of 12VDC with the capability of driving up to 8 load cells (350 ohms) in parallel
Batch Weighing Mode - The high 70 times/second sampling speed makes the AD-4323's two batch operating modes, Normal or Loss-in-Weight batching, perfect for demanding batch weighing applications
Standard Interface Connector and Current Loop - The standard I/O connector allows control of front panel keys and output of comparator/batching controls. Standard serial current loop for connection to remote printer, display or scoreboard.
