YF6-4 wind speed transmitter 4-20mA/for tower crane high-altitude operations

YF6-4 wind speed transmitter 4-20mA/for tower crane high-altitude operationsThe YF6-4 wind speed transmitter is specifically designed for users who measure numerous meteorological parameters, requiring the conversion of wind speed and direction into 4-20mA standard current signals, and is developed and designed to interface with its measurement and control system. The YF6-4 wind speed transmitter with a two-wire 4-20mA system can be applied to industrial sectors such as wind power plants and nuclear power plants, environmental monitoring departments, tower crane wind speed monitoring, etc. It can directly interface with their existing systems, bringing great convenience to system design.

YF6-4 wind speed transmitter 4-20mA/for tower crane high-altitude operationsBasic principle:

The wind speed transmitter uses a three cup rotating frame wind speed sensing element to convert the wind speed into the rotational speed of the rotating frame, and then applies photoelectric methods to convert the rotational speed of the rotating frame into the frequency of the electrical signal. The frequency signal of wind speed is collected and processed by a microcontroller to calculate the average wind speed for three seconds. Then transmit it toIn the DA converter0–5Convert 0m/s wind speed to standard4～20mACurrent signal.
