F850 is a Bessel type low-pass filter that has high-speed A / S conversion and powerful digital processing capabilities of 100 times/sec and a strong attenuation characteristics. SI/FII interface allows easy construction of a network system to communicate with peripherals. F850 is a mid-class loadcell indicator that can be used for wide-ranging applications from weighing scales requiring a high-level sequence such as hopper scales and packing scales to simple applications such as general platform scales. F850X1 is a series controller equipped with a checker function.
