>> HB-8218 Auto Packing Batching Weighing Controller ..................................................

　

The HB-8218 dynamic weighing controller is designed for high speed packing scale and batching seighin control systems. Its especially for hi-speed dynamic weighing control system, Such as high speed packing scale, filling machine, container bag packing, which the performance not only accurate but highj speed.

 

This product measures and controls various kinds of functions needed to design for the automatic batching specially, rigid, simple and compact size design is especially suitable for the various packer, single or multiple batching control system application, It is very easy to controls independently or links use with PLC or control with the computer systems, ItsBatching Controller is designed for auto batching weighing control systems. Its control panel includes the keypad, annunciator LED, instant weight data display and all of the setting data.

 

No doubt, Holbright has over 30 years experiences for design in industrial field to guarantee HB-8218 perfect performance.  

 

 

Standard Features:
  • A/D conversion rate up to 200 times per second, is totally suitable for the high-speed dynamic weighing control system, especially for high speed packing scale or batching system.
  • Can totally display all instant weight data and intact setting data at the same time, such as, main cut-off, dribble cut-off, free fall compensation, final weight, material code...etc.
  • Compact size, rigid construction,- the design of the industrial classification standard.(96mmL X 96mmW )
  • This instrument offers the completely auto batching control system functions.
  • Can be preset and memory up to 16 different materials code.
  • 8 digits totalizer display
  • 7 digits counter display
  • All of material data format can preset, key in and memorized from in the front of panel keypad.
  • All memorized and preset data can be protected in case of power failure.
  • It can offer 13 o/p signal for zero band, main cut-off, dribble cut-off, final weight, free fall compensation, sp1, sp2, sp3, complete, discharge, upper limit, lower limit, error message, control.
  • It can offer 131/P signal for start, emergency stop, ZERO reset, ID code---etc.
  • It can compare to preset data by near zero / lower limits / upper limit / preset tare / inhibit of time / judging of time / complete signal of time / discharge of time.
