T821 Weighing Instrument American Transmission T821 Industrial Weighing Terminal

1、 T821 Weighing Instrument Product Introduction

Product brand:American Transcell

Product series: T821

Product Type: Weighing Instruments, Industrial Weighing Terminals

Product Introduction

(1) Compared to the trade weighing accuracy of ordinary weighing instruments, the high-precision weighing and excellent electromagnetic compatibility performance of T821 weighing terminal make it better meet the process measurement and control requirements in demanding industrial environment applications. The T821 weighing terminal adopts a low-power design and SMT manufacturing process.

(2) From traditional analog output to industrial fieldbus, to modern communication technology's Ethernet network, T821 weighing terminal provides rich interface options for seamless connection with various PC/PLC/DCS. The digital control interface can provide high-speed, stable, and convenient direct control, including packaging/filling/dynamic weight inspection/sorting, ingredients, etc.

(3) The T821 weighing terminal, which can be configured, can be remotely set and calibrated as a transparent and barrier free weighing device in both PLC and PC based automatic control systems. The standard six wire weighing interface, with its long line compensation function, enables accurate conversion of weighing signals from a distance of up to 300 meters.
