The EMA (100) may comprise an EMA housing (102), a strain gauge (202;400) coupled to the EMA housing (102), the strain gauge (202;400) comprising a Wheatstone bridge (300), the Wheatstone bridge (300) comprising a first group of resistors (302,304) coupled in parallel with a second group of resistors (306,308), a controller (502) coupled to the strain gauge (202;400), a variable resistance resistor (308,402) coupled to the Wheatstone bridge (300), the variable resistance resistor (308,402) configured to derive a temperature of the EMA housing (102) based upon a temperature of the variable resistance resistor (308,402) and configured to provide feedback to the controller (502), the controller (502) adjusting a force applied by the EMA (100) based upon the temperature of the EMA housing (102). |
