PROBLEM TO BE SOLVED: To make an indication of an indicator and a transmitted output for remote monitoring positively match each other. SOLUTION: An AC signal inputted from a detecting part detecting the state of the operation of a canned motor is rectified and filtered to be converted into a DC signal by a rectifier-filter circuit 51. Based on the DC signal obtained through conversion by the circuit 51, the state of the operation of the canned motor is indicated by an indicator 52, and the same DC signal is converted into a DC signal for remote monitoring by a conversion circuit IC and outputted fro transmission. In other words by using the common DC signal, an indication of the indicator 52 and a transmitted output value for the remote monitoring are made to match each other. The rectifier-filter circuit 51 and the conversion circuit IC are incorporated, together with the indicator 52, in a closed vessel which is disposed in the terminal box of the canned motor. |
