Frequently Asked Questions about on-board weighing system and TPMS

What is an on-board weighing system?

It is a device installed on board the vehicle consisting of a display positioned in the cabin, to view the load data in real time, and special sensors positioned on the vehicle suspensions (for industrial and commercial vehicles) or on the hydraulic lifting cylinder of the boom (for earthmoving and logistics machinery).

On which application is an on-board weighing system installed?

It is possible to install the on-board weighing system on industrial and commercial vehicles such as tractors, lorries, articulated lorries, tanks, trailers, semi-trailers, vans, etc. and on earthmoving, mining and logistics machinery such as wheel loaders, excavators, forklifts, articulated dump trucks, rigid dump trucks, telehandlers, reach stackers, etc.

How is an on-board weighing system installed?

The on-board display is positioned in the cabin, showing all information relating to the load in real time. In industrial vehicles, special sensors are installed based on the type of vehicle suspension: pneumatic, mechanical or hydraulic. In earthmoving and logistics machinery, sensors are installed on the boom lifting hydraulic system and proximity or angle sensors that determine the weighing point.

Which sectors can benefit from an on-board weighing system?

There are many sectors in which it is possible to benefit from a weighing system installed on board such as aggregate handling, construction, quarrying and mining, transport, agriculture, waste and recycling, port activity, logistics, forestry activities, etc.

What is the accuracy of an on-board weighing system?

Accuracy may vary based on the type of application and the type of sensors installed on the vehicle. Normally the accuracy on industrial vehicles with air suspension is 1% of the total load, with mixed suspensions it is 2% of the total load, with mechanical suspensions it is 3% or 5% of the total load. On the other hand, on earthmoving and logistics machinery, the accuracy is usually 1% and specifically on the excavator it is 3%.

Is the on-board weighing system for internal use or can it be approved?

All OUTSET on-board weighing systems are for internal use. The only system approved by the metric office is the wheel loader weighing system also available in an approved version.

Can I connect the on-board weighing system to the satellite device?

Yes, the on-board weighing system can be connected to any satellite device via serial wiring and the data communication protocol.

Can I transmit the data of the weighing system?

Yes, all loading data and related vehicle information can be transmitted to the office or to external devices or printed on board via a special printer.

Can I receive information / orders from the office to the on-board weighing system?

It is possible to have bi-directional communication of load data, transmitting from the vehicle directly to the office or vice versa receiving work orders directly from the office on the weighing display.

Does the on-board weighing system included on the 4.0 Transition plan (Industry 4.0)?

Yes, on-board weighing systems installed in specific vehicles or machines can be included in the Transition 4.0 plan (Industry 4.0). The system through a cloud portal allows you to geolocate the vehicle, send and receive work orders related to the transported load, view weighing reports and alarms, remote maintenance service, remote diagnosis, etc.

What is the TPMS system?

The OUTSET TPMS is a tyre pressure and temperature monitoring system.

How does the TPMS system work?

The OUTSET TPMS tyre pressure and temperature monitoring system allows constant and direct monitoring of your vehicle's tyres.

What is the main advantage of installing the TPMS system?

The TPMS system allows drivers to always have the right tyre pressure, reduce excessive fuel consumption and keep their vehicles under proper control.

On what vehicles can the TPMS system be installed?

The TPMS system can monitor the tyre pressure and temperature on any type of vehicle, including commercial vehicles, buses, earth-moving machinery, etc.

How are the sensors attached to the tyre?

The sensors of the TPMS system screw onto the tyre valve and constantly measure the temperature and the pressure of the tyres. Each sensor has a safety capsule to prevent it from being stolen or damaged.

How do the sensors on the tyre communicate with the in-cab display and the smart booster?

The wireless sensors on the tire valves communicate with the display and the smart booster via radio.

How many tyres can I monitor?

The TPMS pressure and temperature monitoring system allows constant and direct control of up to 38 tyres per vehicle.

What kind of signal or alarm appears on the display?

The TPMS tyre pressure and temperature monitoring system displays various alarms (7 in total) if tyre pressure reaches an irregular level compared to the set standard pressure. The driver is thus notified of the problem in real time and can avoid damage to the tyre.

When do I receive the pneumatic signal/alarm in the event of tyre problems?

The TPMS tyre pressure and temperature monitoring system allows immediate and constant control of the vehicle’s tyres. In the event of tyre problems, the alarm is displayed and sounded at the same time as the anomaly is indicated on the in-cab display.

Can I connect a trailer and/or a semi-trailer and monitor the pressure of the tyres?

The TPMS tyre pressure and temperature monitoring system allows easy and automatic reading of multiple trailers and semitrailers thanks to the Smart Booster. The in-cab display not only receives the pressures and temperatures of the tyres on the tractor unit, but also receives all the pressures and temperatures for the connected trailer.

What are the differences between FIXED semitrailer, FLEET semitrailer and EXTRA semitrailer?

There are three types of semitrailer kits: FIXED for semitrailers permanently coupled to the tractor, FLEET for semitrailers that can be interchanged on the tractor and EXTRA for semi-trailers when the tractor is already fitted with the TPMS system.

What are the differences between FIXED trailer, FLEET trailer and EXTRA trailer?

There are three types of trailer kits: FIXED for trailers permanently coupled to the truck, FLEET for trailers that can be interchanged on the truck and EXTRA for trailers when the truck is already fitted with an TPMS system.

Can the information about the tyre pressure and temperature be sent directly to the office?

With the RS display version, any GPS system can be connected to the RS232 port of the display to send all data and alarms recorded directly to the office.
