A method of obtaining sealing steam temperature readings in a steam turbine where steam is used to seal turbine shaft ends includes (a) supplying pressurized sealing steam through a supply pipe to a steam seal header that, in turn, distributes the sealing steam to the shaft ends, respectively; (b) measuring temperature of the pressurized sealing steam at a location immediately adjacent at least one shaft end, downstream of the supply pipe; and (c) using temperature measurements from step (b) to insure that the pressurized sealing steam is within a predetermined acceptable range.
