PURPOSE:To achieve a highly reliable transmission of signals with a simple noise control by transmitting any of a measuring signals from the detection side and driving signals to a checking device from the measuring side to the detection side through an optical cable using a light signal. CONSTITUTION:After shaped in the waveform, a detection signal from a radiation detector 1 on the detection side is converted into a light signal with a light- electricity converter 7 and transmitted to th measuring side 101 via an optical cable 10 connected to a light branching filter 9 for telemetering of a radiation with a photoelectric converter 12, a measuring device 6 and the like. On the other hand, a driving signal converted into a light signal with an electricity- light conversion circuit 13 on the measuring side 101 is likewise transmitted to the detection side through the optical cable 10 and a checking device 3 is driven to check the detector 1. Such a simple noise control eliminating the shield of a single transmission cable enable a highly reliable transmission of signals with a strong noise resistance. Thus, a radiation telemetering can be set up. |
