Small Wind Speed Sensor

Product Manual

The three-cup wind speed sensor is a wind speed measuring instrument independently developed and produced by our company. The sensor shell is made of PCmaterial, which has good anti-corrosion and anti-corrosion characteristics, which can ensure that the sensor is free of rust for long-term use. coupled with the smooth internal bearing system, ensures the accuracy of information collection. Internal integration of photoelectric conversion mechanism, industrial microcomputer processor, standard current generator, current driver, etc.

(1)The sensor has a compact design and high measurement accuracy.

(2)Fast response and good interchangeability.

(3)Really realize low cost, low price and high performance.

(4)The flange installation method can realize the bottom line and the side line, which is simple and convenient.

(5)The power supply has a wide adaptable range, good linearity of data information, and long signal transmission distance.

(6)It has two parameters, wind speed and wind level, with reliable data.

This product is widely used in the fields of construction machinery (cranes, crawler cranes, gantry cranes, tower cranes, etc.), as well as wind speed measurement in fields such as railways, ports, docks, power plants, meteorology, cableways, environment, aquaculture, air conditioning, energy-saving monitoring, agriculture, etc.

4.2 Impedance Requirement of Current Signal

The Wind Speed Sensor can be connected to various data collectors with differential inputs, data acquisition cards, remote data acquisition modules and other equipment. The wiring instructions are as follows:

V: voltage value collected by the collector, unit: V;

A: The current value collected by the collector, unit: mA;

P: The number of pulses collected by the collector within 1s, unit: piece;

RS485 signal(Default address 01):

Standard Modbus-RTU protocol, baud rate: 9600; Check bit: no; Data bits: 8; Stop bit: 1

7.1 Modification Address

For example: Change the sensor with address 1 to address 2, Host→Slave

If the sensor receives the correct data, the data will be returned in the same way.

Note: If you forget the original address of the sensor, you can use the broadcast address 0XFE instead. When using 0XFE, the host can only connect to one slave, and the return address is still the original address, which can be used as an address query method.

7.2 Query Data

Query the data (wind speed, wind level) of the sensor (address 1), host→slave.

If the sensor is received correctly, it will return the following data, slave → host.

(1)Please check whether the packaging is in good condition, and check whether the sensor model and specifications are consistent with the products you purchased.

(2)No live wiring is allowed, and the power can be turned on after the wiring is checked and checked.

(3)The user should not change the components and wires that have been soldered after the product leaves the factory.

(4)The sensor is a precision device, please do not disassemble it by yourself when using it, let alone touch the diaphragm, so as to avoid damage to the product.

The warranty period of this product is one year. Counting from the date of shipment, within twelve months, failures caused by sensor quality problems (non-human damage). The company is responsible for free maintenance or replacement, and only cost prices after the warranty period will be expired.
