Turbine speed sensors are used to monitor the rotation speed of turbines in complex systems like jet engines or turbocharged car engines. Turbines can range from simple, like the single-moving-part vent on a house, to highly complex arrays of alloy blades in a jet engine that generate thrust. A turbine speed sensor provides critical information on how systems like jet engines or turbocharged air intakes are functioning in real-time by measuring the turbine's rotational speed.
