Checkpoint M-NH

The Checkpoint M-NH satisfies the need for accurate mid-range checkweighing in extreme production environments. It is designed for frequent cleaning with high-pressure water jet and is protected against the corrosive effects of steam and harsh chemicals.

Whether checking current nominal weight or sorting and classifying, the Checkpoint M-NH will reliably meet your application requirements with speed and efficiency.

The Checkpoint M-NH has a welded support structure fabricated from heavy-walled, stainless steel tubing upgraded to IP66/NEMA 4X. The entire frame is covered with polished 316 stainless steel sheet metal to form a smooth, crevice-free enclosure with sloping surfaces for easy cleaning and superior water resistance. The Weigh Cell and conveyor drive motors are fully contained within this enclosure. For additional protection, the Weigh Cell and photocell are encapsulated within their own housings, and the conveyors are equipped with chemical resistant sealed bearings. Electrical connections are also designed to ensure the water-tight integrity of the entire structure.

Individually modified solutions for varying product shapes are easily accommodated. Spring-loaded rollers allow easy belt exchange without tools.

Standard configuration

  • Welded stainless steel (AISI 316) tubular frame with stainless steel control cabinet and operating column (IP66/NEMA 4X)
  • Integrated display/control system with 5.7" graphical touch screen
  • 2 transport conveyors (infeed and weighing)
  • 1 set - operator/maintenance manual, electrical and pneumatic drawings, spare parts catalog

The Checkpoint M-NH is available with a built-in printer or data storage system, sorting devices and a wide range of additional options for enhanced performance.

Operational Features

  • 100% production monitoring of products to ensure they meet the minimum weight or average weight requirements with production documentation
  • Rejection of out-of-tolerance products via optional flap conveyor or diverter gate
  • Production documentation shown by means of graphic screens for statistics histogram, trend and average value curves by pieces, hours or minutes. 2 different weighing ranges
  • 5 weight classes for under, accept and over classification
  • 50 PLUs (incorporates all relevant information required for the assigned product)
  • Touch screen simple, menu-guided operation
  • Multi-level password protection
  • 3 different working height ranges
  • Right to left or left to right working directions
  • Simple belt and conveyor change, no tools required
  • Maintenance-free servo drive includes motor and electronics
  • Compact design for easy integration into production lines
  • Line synchronization with isolated relay contacts
    • Remote start (input)
    • Weighing mode (output)
    • Error (output)
  • 20 automation channels available: eight input and 12 output channels
  • Main power switch located on electrical cabinet
  • Photo cell for product recognition (fully enclosed in a waterproof housing for complete protection)
  • Simple menu-driven calibration
  • AutoZero tracking capabilities
  • Tare weight input for checking net weights
  • Standard statistics including totals, over/under weights, standard deviation, average, etc.
  • Bubble level on frame for accurate machine leveling
  • Emergency by-pass for "worst-case scenario" resets the checkweigher to "product transport with the last selected speed" - Production can continue uninterrupted and the weight check can be performed at a later time
  • Add-on capabilities for even greater application flexibility
  • The basic model of the Checkpoint M-NH covers an extraordinarily wide and versatile spectrum of applications. This versatility is supplemented by many selectable options.
  • The Checkpoint M-NH can be equipped with a mean value control (MVR-1). This feature allows the control of automated filling machines. It is a valuable tool to reduce and/or eliminate inefficient overfilling. The
