On-board Weigh Scales (Air)

The Plastecnic On-Board Weigh Scale is a system for vehicles with air suspension and comes as a complete kit, designed for easy self-installation.

The system consists of a single-DIN in-cab unit which displays the gross vehicle weight (GVW), net weight and the axle group weights in real-time.

The system is also able to transmit live weight data via Bluetooth to a nearby Android tablet or mobile phone, allowing weight data to be viewed remotely outside the cab – particularly useful for single-man loading.  In addition to displaying live weight values the phone also displays a traffic-light style weight representation.

Both the phone and the single-DIN in-cab unit produce an audible overload alarm when a pre-selected weight level is reached.

As an optional feature, weight data can also be transmitted to on-board telematics devices (including TomTom LINK) via either RS-232 or Bluetooth, from where data can be integrated into a third party fleet management program (e.g. TomTom WEBFLEET).

This system is ideal for multi trailer “drop & swap” and is suitable for all trailers types, including:

  • Tipper
  • Walking Floor
  • Ejector
  • Flat Bed
  • Tanker
  • Curtain Sider.

The system is accurate to within ±0.5%.  An in-cab printer option is also available.

Note – this product is for vehicles with all-air suspension.

Additional information

Android App

The accompanying free Android app turns your mobile phone or tablet into a remote control for the on-board weighing system, communicating with the in-cab unit via Bluetooth. The app allows you to improve the loading process and adjust the maximum weight per axle and the maximum gross weight desired.

The loading percentage and the difference to the programmed weight is shown on-screen, with the weight value changing colour as it approaches or exceeds the programmed maximum. An optional alarm will sound to indicate that you are approaching the maximum weight programmed.


• Shorten the process of loading and unloading
