High Volume, Low Cost OEM Scale Designs and Weighing Systems

RL Scales weighing systems for automatic self-checkout, in-store and similar applications These scale designs, use Mini-Mount load cell mounts

Whether it’s for a commercial application such as self-checkout, commercial and industrial light capacity or conveyor scale, we have the knowledge and capability to design high-accuracy and high-speed weighing systems.  Furthermore, we manufacture them in high volume.  Our RL Scales design team consults with the client to provide confidential conceptual scale designs.  These include new, innovative methods of weighing to meet unique new demands or to meet critical cost goals.

RL Scales Self-Checkout scale components

Scale-Tron's 1410 analog transmitter handles up to 8 load cells and gives 0-20 mA, 4-20 mA, 0-5 V or 0-10 V output

Scale-Tron's RL Scales division is one of the leading manufacturers of bag scales for the self-checkout industry. We supply extreme accuracy, high speed scales to the world's leading producers of automatic checkout point of sale (POS) terminals. These 'S.C.O. scales' sit under the bag-racks and carousels of many self-checkout counters worldwide. They measure the change in weight for each product scanned, checking the weight against the internal database. As a result, the honesty of the people scanning their purchases is verified. Past and present scale designs include the following. You can use these scale components in your own scale designs with confidence, knowing that they are well-proven and reliable. Or you can ask us to create new weighing systems for you . . . Read more

Load cell mounts for scales

  • Fixed size platforms on large single-point load cells.
  • RL Scales ‘Scale-Bars’ with single-point load cells inside a set of two U-channel frames.  These are used for support of platforms with various lengths.  Different models suit different platform widths.
  • Conveyor scales and conveyor load cell mounts for use in self-checkout, with special conveyors using balanced drive drum motors.
  • RL Scales Carousel platforms, with ‘X-frame’ bottom structures, ‘brick’ style single-point load cells and ‘star’ type top frames with wheels supporting the rotary platforms.
  • RL Scales Planarcell (patented) planar load cells in cast metal bases with overload protection.  Use four Planarcells to support a platform of practically any size.
  • RL Scales Mini-Mount (copyright protected) mini-single point load cells in cast metal bases with overload protection.  Use four Minimounts to support a platform of practically any size.

Weight transmitters and associated electronics

  • RL Scales transmitter model 1932 giving 20,000 division resolution and very fast response while rejecting shocks and vibration.  RS232 communication, supports up to four load cells and uses standard terminal emulator software for setup and calibration.  Superseded by 1945, below.
  • RL Scales transmitter model 1945 giving 20,000 division resolution, very low noise and jitter and very fast response while rejecting shocks and vibration. USB communication, supports up to four load cells and has a dedicated Windows application for setup and calibration.
  • Scale transmitter DJB2  giving 24 bit resolution and raw, unprocessed 4-channel output.  RS485 multi-drop communication, supports up to eight load cells.  Because of addressed commands, can communicate with multiple scales on a single RS485 cable.
  • Scale transmitter model 1410 (pictured at right), single channel analog processing with variable gain and offset, plus variable signal filtering.  Supports up to eight load cells.  Output is 0-20 mA, 4-20 mA, 0-5 V or 0-10 V.  Bare board, NEMA-4 enclosure or DIN rail mounting.
  • Summing unit model 1280 with DIN rail mount, NEMA-4 enclosure or bare board handles 2 or 4 load cells.

Industrial Weighing Systems

Minor ingredient batching scales sit on load cells to weigh vitamins, colors and other powdered ingredients in wide ratiosAs a result of our 40 years experience in industrial weighing systems, we have a unique knowledge of all types of load cell, custom electronics and computer software.  Because of this, we can offer solutions from a single design load cell weighing system to high quantity applications.  Contact us for design ideas and pricing.  We also provide:

  • CraneWeigh, measures crane load weight with bolt-on sensors.
  • Load cells and mounting assemblies.
  • On-hook crane scales with radio communication to indicator at floor level.
  • Platform scales of any size and quantity, from 200 g capacity to truck and rail scales.
  • Weight indicators and weight transmitters.
  • Special sensors for load sensing, custom designs and applications.
  • Silo inventory systems by weight.
