Abstract: The subject matter of this specification can be embodied in, among other things, an actuator that includes a piston configured to actuate relative to a housing, a sensor rod configured to be actuated by the piston, a sensor affixed to the housing and configured to detect a piston position of the piston relative to the housing based on a sensor rod position of the sensor rod relative to the sensor, and a linkage configured to couple the sensor rod to the piston, and to offset a change to the sensor rod position due to a temperature-induced dimensional change to at least one of the housing, piston, the sensor rod, and the sensor.
