turbine speed sensor
TD and UTseries of travel sensors are high performance displacement sensor.They apply to measuring turbine cylinder expan-sion,valve opening status,and ather displacement valves.Because of its durability and high accuracy,it has a wide application.
TD and UT series of travel sensors both use the principle of electromagnetic induction.It consists of an oscillation circuit,a constant current source and a detdctor.There are two coils around an iron core inside this travel sensor,the coils can move inside the sensor shell.When the coils are excited by an AC voltage of a certen frequency,an electric signal will be generated,whitch is related to the displacement of the iron core.
