DEVICE FOR TESTING PERFORMANCE OF CYLINDER HEAD MOVEMENT MEASURING GAP SENSOR

摘要

PURPOSE: A device for testing the performance of a cylinder head movement measuring gap sensor is provided to accurately measure the performance of a gap sensor regardless of heat when a condition of high temperature is applied. CONSTITUTION: A first thermocouple(16) is installed near a gap sensor(12). An electric heater(17) is installed on a sensor bracket(13). A temperature controller(18) controls the electric heater by receiving a sensing signal of the first thermocouple. A second thermocouple(19) is installed near a target(14). A temperature indicator(20) outputs the sensing signal of the second thermocouple to a screen. A supply hose(22) has a cut-off valve(21) insulating the heat transmitted to a measurer(15). A water tank(23) stores the cooling water.
