Instrumentation and Balances


RUAG Aviation's instrumentation specialists are actively engaged in serving you promptly and efficiently. This means that all our experience, engineering skills and workmanship flow timely into your measurement needs.

Strain Gauge Balance

Through the long time experience in wind tunnel testing, RUAG Aviation is able to engineer, design and build trusted strain gauge balances. These balances provide the necessary accurate data for various wind tunnels worldwide as well as for the RUAG in-house research labs.

Besides the standard block type balance family, RUAG Aviation designs balances for high and dynamic loading as well as for wheel and model component measurements.

Balance Families

Two balance families are available, each with a number of scaled balances: Standard type series 1xx and high-load series 7xx. In order to simplify the critical selection process RUAG provides a selection tool based on EXCEL spreadsheet (see also publication section below). You only have to enter the maximum measurement loads and a suitable selection is shown.

In addition to our families we  provide customized solutions such as multicomponent rotating shaft balances inclusive data transmission,  wing/wheel balances for car models or balance crossings.

For your convenience, all RUAG balances are also available for rent – an attractive option for short projects within a tight timescale.


The need to acquire pricise physical properties such as the measurement of strains, pressures, temperatures and accelerations are applied in many fields other than wind tunnel testing.

The health of train wheels is assessed at focal points of the Swiss railway network through analysis of the loading signals of the train running over the rail at normal speed. This harsh environment – exposure to extreme temperatures, humidity, vibrations etc. – poses many challenges and can only be overcome by clever design and meticulous handicraft.

Experimental structural testing using strain gauges is necessary in a wide range of applications from aircraft and sub-assemblies down to individual components such as wind turbines, buildings, machine beds and many others. These tests enable the engineers to compare the experimentally acquired data with the predicted stress or fatigue results from design calculations.
