弁開度検出装置。 An amplification mechanism that amplifies the amount of movement of the valve body is attached to the valve stem, and a scale with graduations for generating optical pulses formed at regular intervals is attached to the output section of this amplification mechanism.
A light transmitting/receiving fiber constituting a photoelectric switch is provided on the fixed side in a non-contact state with the scale, and a travel amount calculator is provided to count the light pulses from the light receiving fiber and calculate the valve opening degree. Valve opening detection device.
