SAVVY® Sensor – LoadCell at a glance

Measurement method

The measuring principle is based on strain measurement. When the wagon is loaded, the load generates strain in the supporting structure of the bogie. This strain is detected by the sensor and transmitted to the telematics on the wagon via radio using the SAVVY® SenseGateway-ExR. The telematics further sends the data to the web-based SAVVY® Synergy Portal via the cellular network.

Easy installation

SAVVY® LoadCell-Ex is optimized for easy installation by simply clamping it directly to the bogie. There is no need for time-consuming welding, drilling or glueing, so the downtime of the freight car is minimal and it is ideal for retrofitting. In appropriate applications, the sensor can be mounted directly with two screws.

Measurement data collection

The measured values are recorded via SAVVY® SenseGateway-ExR and transmitted to the telematics unit by radio. Up to four different sensors can be connected simultaneously. SAVVY® SenseGateway-ExR has an ITSS IF2 standard radio interface (2.4GHz). Thanks to the internal battery, the device is designed for maintenance-free operation for more than 10 years.


For data transmission to the cloud, you can use the SAVVY® FleetTrac-M1, SAVVY® CargoTrac-ExR-M1 or SAVVY® CargoTrac-Solar. The devices are suitable for a wide variety of transport units such as containers, IBCs and freight cars.


SAVVY® LoadCell-Ex complies with the European ATEX Directive 2014/34/EU and may therefore be used in Zone 1 and 2 hazardous areas for gases up to Group IIC T6/T4, and also in Zone 21 and 22 for Group IIIC dusts.

Integrated and wireless

The measured and transmitted data are clearly processed in the SAVVY® Synergy Portal or can be queried via interfaces thanks to ITSS IF 1 conformity. All changes in configuration, measurement data and firmware updates are wireless (over the air).


SAVVY® LoadCell-Ex is a weighing sensor that can be mounted on existing freight cars without mechanical modification. The payload is determined on-board. This not only increases wagon availability but also transport safety.

The entire sensor system is approved for hazardous applications and areas.
