YF6-4 wind speed transmitter 4-20mA/tower crane high-altitude operation YF6-4 wind speed transmitter is specially developed and designed for users who need to measure numerous meteorological parameters, convert wind speed and direction into 4-20mA standard current signals, and integrate them with their measurement and control systems. 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/tower crane basic principle for high-altitude operations:
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 it is transmitted to the DA converter to convert the 0-50m/s wind speed into a standard 4-20mA current signal.
2、 Main technical indicators:
1. Wind speed measurement range: 0 m/s to 50 m/s
2. Wind speed measurement accuracy: ± (0.5+0.03V) m/s (V is the actual wind speed)
3. Output format: 2-wire 4-20mA current loop.
4. External loop resistance: R loop ≤ (Vmin-9)/0.02 Ω, where Vmin is the output voltage (V) of the 24V power supply
5. Working environment: Temperature: -40 ℃ to+50 ℃
Humidity: ≤ 100% RH (no condensation)
6. Dimensions: Wind speed transmitter: Φ 186mm × 232mm
7. Weight: Host: 0.68kg
3、 Performance characteristics:
1. The transmitter housing adopts an all metal structure and is coated with an anti-corrosion layer, greatly improving the anti acid rain corrosion ability of the instrument during use. In addition, the circuit is designed with
The timing is specially designed with lightning protection circuits.
2. In order to prevent damage to the transmitter due to incorrect polarity connection of the circuit, specialized anti polarity reverse circuit measures are adopted in the transmitter.
3. The host is connected to the transmitter through a 4-20mA current loop, which is used to transmit wind measurement signals and provide sensing at the same time
The working power supply for devices, microcontrollers, converters, etc., and also provides the reference voltage required for DA transmitters.
4、 Basic purpose:
The YF6-4 wind speed transmitter has a simple structure and high degree of automation, and can continuously monitor instantaneous wind speed. It is suitable for real-time monitoring of wind speed in departments such as airports, ports, tower cranes, and fire prevention that are very concerned about wind speed.
