Models TV-110-L2 and TV-114 are also the same size, use the same exterior gold anodized components but utilize different sensing schemes. The Model TV-110-L2 uses an optical sensor assembly with a multi-slotted disc attached to a shaft directly coupled to the wind cup rotor assembly, thus producing a pulse train whose frequency is proportional to wind speed when supported by proper signal conditioning electronics or datalogger connection. This type of sensor mechanism is usually called a photo-chopper. Model TV-114 uses a brushless AC generator to produce an output of nominally 0 to 4.7 VAC representing 0 to 100 MPH. This unit can be interfaced to datalogger but may require some signal conditioning electronics to produce a more uniform signal over the range of speeds. Probably our most rugged and certainly our most widely used wind speed sensor. It is used on the Model 220-19R wind monitor, the WSC-5 Series of wind activated controllers, the Model 2-200 wind speed indicator and many of the customized modular meteorological systems of the 3000 Series.
