Sentinel Scale System

Sentinel Onboard Truck Scale System

Sentinel is the Gold Standard when it comes to wireless onboard axle weight monitoring systems for trucks and trailers. The monitor, which can be held in the palm of your hand, displays all your weights simultaneously and in real time. In a blink of an eye, the pictogram facilitates the locating of the load weight and its distribution. Weights are displayed in net or gross weights and converted to the selected unit (kg, lbs or ton). Pictograms of popular trucks and trailers are available in the monitor’s memory. Sentinel is the tool of excellence for remote work with a margin of error +/- to 0.01. It allows an 8 channel axle group display. Sentinel is very useful if your truck has a multiple configuration of several semi-trailers and train.

This portable weight monitoring device displays your weights in real time in a 258 metres radius (845ft) around the truck. It is very useful for applications where loading control is done outside the truck’s cab. The display’s small size allows you to carry it in your pocket. A protective case is also included.

Sentinel is designed for all spring ride and air ride vehicle suspensions. Installation is simple, with no cables to install in the cab. Installed modules on vehicles are powered by the vehicle, therefore no battery to change on a regular basis which reduces costs and allows for quick display.

For vehicle fleets, the Sentinel axle weight monitoring system is the number 1 choice. The recognition of other units allows coupling the new trailer without typing the address manually. This adaptability allows you to interchange an unlimited number of trailers quickly and easily.

It is possible to print load data on a wireless printer. The printer order can be given inside as well as outside of the truck’s cab. It is also possible to transmit data over the RS232 wireless port to an onboard computer.
