Abstract
An interior space of the at least one housing of a force-measuring device is filled with a gas composition that is distinguishable in at least one parameter from the ambient atmosphere. A sensor that is arranged in the interior space, or on the housing, measures this distinguishable parameter. A processing unit of the force-measuring device compares signals obtained from the sensor to monitor and determine the condition of the force-measuring device.
