PURPOSE: A device for monitoring a ventilation fan blade angle adjusting unit of a thermoelectric power plant is provided to convert the displacement of a core moving forward and backward inside a sensing hole into electrical signals and to indicate the converted electric signals with a digital indicator, thereby accurately monitoring an angle of a ventilation fan blade being adjusted.;CONSTITUTION: A device for monitoring a ventilation fan blade angle adjusting unit of a thermoelectric power plant comprises a hollow rack bush(80), an output member(90), a sensing unit(110), and a digital indicator(120). The output unit monitors a range that an angle of a ventilation fan is adjusted by the operation of the rack bush. The output member includes a plate arranged inside the rack bush and a supporting rod connecting a core by being protruded in a rear side of the plate. The sensing unit is arranged to be faced the rack bush and converts the displacement of a core moving linearly into electrical signals. The digital indicator connected to the sensing unit displays the converted electrical signal according to the adjusted angle of the ventilation fan blade.;COPYRIGHT KIPO 2013
