Providing alternative energy design engineers with a means of reliably and accurately detecting the speed of wind turbines, TT electronics Optek Technology Inc.’s OPB732 series long-distance infrared reflective switches have been employed in a 6-kW wind turbine for revolutions-per-minute (RPM) sensing. Placed at the turbine rotor, the switches are used internally to sense RPMs, and that data is then transmitted to a customer-accessible Web site via General Packet Radio Service. With its noncontact design, which features an emitter and a sensor protected from contaminants by a clear window, the reflective switch provides the reliability and accuracy necessary for monitoring turbine RPMs. It also is suitable for use in assembly line and machine automation, equipment security, door sensors, machine safety, end of travel sensors and noncontact reflective object sensor applications.
