1. An adjustable inlet guide vane angle monitoring device for monitoring an angular position of an inlet guide vane mounted about a compressor of a gas turbine engine, comprising:
a position sensor attached to the inlet guide vane;
an adjustable sensor plate configured for attachment to the position sensor;
wherein the adjustable sensor plate comprises a first plate and a second plate slidable therewith such that the overall dimension of the adjustable sensor plate may be adjusted; and
a limit switch positioned about the adjustable sensor plate;
wherein, when the adjustable inlet guide vane angle monitoring device is installed and operational, the position sensor determines the angular position of the inlet guide vane and the limit switch prevents further angular movement of the inlet guide vane upon detection of the adjustable sensor plate.
