Abstract
The applicability of wirelessly interrogated passive ID-tag type SAW sensors for measurements of the temperature of disc brakes of moving railway cars is shown. Here, a short radio channel allows relatively simple radio impulse processing by phase evaluation. Further, using elastic convolver measurement in large steel works, we discuss the feasibility of passive SAW sensors in a severely obstructed radio channel with interference. For such environments radio signals of the spread spectrum type and a receiver with the corresponding correlative SAW structure or a RAKE receiver are appropriate for remote readoutKeywords
