Testbed for sensors
DotX designed and produced a testbed for a wind turbine manufacturer to analyse the low-frequent behaviour of acceleration and rotational speed sensors.
An accurate stepper motor (number 1, in photo below) drives a belt. The belt is connected to a mounting frame (number 2) for the accelerometer. In addition, the belt drives a rotating shaft (number 3). This shaft can be connected to a rotor speed sensor.
