They also do pulse versions, and wind vanes etc; (numerous sellers but, I expect, one manufacturer).

I think all three of those links are Pulse outputs. The second is interesting because it also includes a direction vane, which is "20 mA current output" (that can be converted to 0-5 volts range with a 250 ohm resistor). The anemometer gives 5 volt pulses.
The details with the first link are :
Pulse output type: PNP output
Sensor style: three cups
Voltage: 0-5V
Power supply: 12-24V
Measurement range: 0-30m/s or 0-60m/s
Resolution: 0.1M/S
The interface for the "PNP Output" might need a pull-down resistor and I suggest also a diode to block current flowing into the anemometer input pin of the transmitter board (to prevent "Phantom Powering" or more serious damage).
Cheers, Alan.
