PROBLEM TO BE SOLVED: To obtain a rotary body telephotometer which is noise-resistant by means of a digital processing, can measured even at a high-speed rotation and is comparatively compact and inexpensive by providing a measuring means, an optical transmitting means, a light receiving means and a processing means which are respectively specified. SOLUTION: Thermocouple 1 and 2 for measuring temp., for example, are mounted on the inner diameter surface of a rotary shaft 11 as measuring means. The light transmitting means (a rotation side processing part 20, a battery 3, a light emitting diode 31 and a photodiode 32) is mounted on a rotary body for converting a measurement signal from the measuring means into a digital light signal. The light receiving means (the photodiode 42, the light emitting diode 42 and a fixed processing part 50) is provided on the fixed side for receiving the digital light signal from the light transmitting means and demodulating it into a digital measuring signal. The processing means (an I/O interface 4 and a personal computer 5) processes the digital measuring signal from the light receiving means. |
