タを設けた遠隔計測伝送装置。 A master station and a plurality of slave stations are connected to each other by a transmission line, and in response to a measurement data request from the master station to each slave station, the output signal of a measurement sensor managed by each slave station is used as measurement data. In a remote measurement transmission device that transmits data from each slave station to the master station,
Each slave station is provided with a V/f converter that converts the output signal of the sensor into voltage/frequency and outputs the voltage/frequency converter,
A remote measurement transmission device, wherein the master station is provided with an f/V converter that converts the output signals from the respective V/f converters into frequency/voltage.
