Technical description

The strap is routed under two completely detachable shafts

over the measurement body (sensor). The shafts can be

detached using a ball locking device by pressing a button.

The shafts can still be rotated in the locked state. The

applied force causes strain of the measuring point of the

base body. The deformation is measured using strain gauges.

The wiring of multiple strain gauges for a full bridge circuit

compensates for the temperature influence on the zero

signal. The very light belt force sensor made of titanium

minimizes the influence of the measuring system due to the

low own weight of the sensor. The system-inherent non-

linearity can be partially compensated for by an optional

integrated linearization circuit.

The standard version without linearization is already shipped

with calibration according to ISO/ TS 17242 (third degree

polynomial approximation).
