PURPOSE: A linear setting device for a seal gap measurement sensor for an air preheater is provided to accurately control a driving unit by reading a signal as a linear setting value even if the signal, which is input from a seal gap measurement sensor into an integrated control controller, is nonlinear. CONSTITUTION: A linear setting device(10) for a seal gap measurement sensor for an air preheater comprises a sensor(30) for setting, a linear correction unit(50), and a control panel(70). The linear correction unit receives a signal detected at the sensor for setting and transmits a value, which is corrected from information about nonlinear graph of voltage to a linear graph, to an integrated control controller(200). The sensor for setting includes a displacement sensor and a magnet. The displacement sensor has a probe(31a) connecting to the upper surface of a rotor. The magnet attaches the displacement sensor to a sector plate(720). [Reference numerals] (200) Integrated control controller; (50) Linear correction unit; (70) Control panel |
