Reflective Switch Employed in Wind Turbines for RPM Sensing

The OPB732 Series long distance infrared reflective switch from TT electronics OPTEK Technology (Carrollton, TX) has been employed in a 6kW wind turbine for RPM sensing. Placed at the turbine rotor, the switch is used internally to sense RPMs, and that data is then transmitted to a customer-accessible Web site via GPRS.
