Abstract:
1. An electromechanical actuator (EMA) comprising: 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; and 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 resistance 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, wherein the controller is configured to measure a resistance of the variable resistance resistor to obtain a temperature of the EMA housing.
