Electromechanical actuator strain gauge temperature compensation device
Abstract:
The EMA may comprise an EMA housing, a strain gauge coupled to the EMA housing, the strain gauge comprising a Wheatstone bridge, the Wheatstone bridge comprising a first group of resistors coupled in parallel with a second group of resistors, a controller coupled to the strain gauge, a variable resistance resistor coupled to the Wheatstone bridge, the variable resistance resistor configured to derive a temperature of the EMA housing based upon a temperature of the variable resistance resistor and configured to provide feedback to the controller, the controller adjusting a force applied by the EMA based upon the temperature of the EMA housing.
