Product IntroductionThis anemometer is a device for measuring wind speed in construction machinery (cranes, crawler cranes, portal cranes, tower cranes, etc.) railways, ports, docks, wind power generation, photovoltaic power generation, power plants, meteorology, ropeways, environment, greenhouses, breeding and other areas. It can be used to realize the digitization and automation of equipment wind speed indication, and it is an indispensable wind speed detection equipment for related equipment.The anemometer is composed of three parts: intelligent measurement and control instrument wind speed sensor and cable. Only the measurement and control instrument adopts single-chip microcomputer and corresponding external circuit module. The display part adopts single-window highlight digital display. The wind speed sensor adopts a high-precision wind speed sensor for marine military use. Compared with traditional products, it has the advantages of high accuracy, wide range, high input line resistance, convenient observation, stability and reliability.FeaturesThis product integrates electronic technology and microcomputer technology. Its main functions are as follows:a. It can automatically monitor the wind speed signal and input it into the instrument for computer processing: display the wind speed and civil strength level (the display can be switched by pressing the button)b. The instrument can automatically alarm the preset parameters and output a normally open or normally closed switch signal.c. It can automatically detect the maximum wind level of the day, and restore the "0" level after the power is turned on again.Technical index:1. Wind speed index1) Wind speed measurement range: 0-56m/s, 0-16 level2) Accuracy<56m/s±(0.5+0.05v), ≥56m/s±5%3) Starting wind speed of wind speed sensor: <0.7m/s4) Displayable parameters: actual wind speed, wind force, gust temperature2. Alarm limit value (indicator factory setting): the jacking state is (level 4), the working state is (level 8), the limit value can be adjusted according to customer requirements (can be selected)3. Pulse output 0~800HZ (0~56m/s)4. Working environment temperatureHost: -30°C~65°CSensor: -30°C~65°CStandard wire length:10m
5 advantages：
The wind cup of the wind speed sensor is made of high weather resistance, high strength, corrosion resistance and waterproof metal. The sensor shell is made of aluminum-magnesium alloy. The internal circuit is sprayed with three anti-paint treatment. The whole sensor has good resistance to harsh environments. Sex. The output of wind speed sensor is frequency signal, 4^20mA current signal, 0~5V or 1^5V voltage signal.
The main engine of the anemometer is composed of signal processing circuit, single-chip circuit, digital tube display alarm control circuit, the chassis is made of steel plate galvanized and plastic sprayed case, and the box is equipped with a high-reliable power supply, with extremely reliable anti-electromagnetic interference ability, high and low voltage protection Ability to ensure that the host can work normally within the range of -40℃~60℃ and humidity of 10% to 95%.
Self-service alarm circuit：When the wind speed exceeds the pre-warning wind speed, it will sound an automatic alarm and power off at the same time to remind the staff to pay attention.
a.The core of the mainboard adopts the self-developed MS51 single-chip microcomputer mainboard and its supporting standard I/O board, plus the corresponding signal conditioning module, which can flexibly change the data acquisition and output control, and the reliability is further improved;
b.Low power consumption, all digital circuits use CMOS chips
c.With power-off memory function, it can work continuously for a long time;
d.It has strong anti-electromagnetic interference function;
e.All keyboard operations for installation and commissioning bring great convenience to users to adjust after changing crane conditions.
f.The wiring terminals on the back panel of the instrument are convenient and clear;
g.With sound alarm function.
Scope of application
Anemometer is a device for measuring wind speed in construction machinery (cranes, crawler cranes, portal cranes, tower cranes, etc.), railways, ports, docks, wind power generation, photovoltaic power generation, power plants, meteorology, ropeways, environment, greenhouses, breeding and other fields.
Instructions for use
On-site installation, commissioning and use1. Main engine installation: The main engine is installed in the tower crane cab and should be fixed in an appropriate position with good stability. (1) The main engine must be firmly fixed in the tower crane cab, and the vibration and turbulence of the tower crane shall be fully considered to ensure that the main engine cannot be loosened during use.2. Installation of anemometer sensor: The anemometer sensor is installed above the tower crane's cab and fixed (fixed if necessary). After the anemometer sensor is installed, ensure that the installation position is level and the tower crane will not fall off during operation (wind cup sensor size 220×87×230mm)
Automatic alarm circuit
When the wind speed exceeds the pre-warning wind speed, the sound will automatically alarm, and the power will be cut off at the same time to remind the staff to pay attention
Installation of wind sensor:
The phoenix speed sensor should be installed on a bracket that is 500-600m away from the horizontal plane and the height of the ground or ship deck.
InstructionsSetting: This button is the wind warning setting button;The pre-alarm wind power level is preset to level 6 (the product has been set at the factory). When setting, each time the button is pressed, it can be set in 0.5 level/each time, and the highest can be set to 12 levels, and the circuit will perform corresponding alarm linkage output.
Instructions for useDuring normal work: the window wind speed displays the current real-time wind speed; after pressing the wind speed and wind keys to switch, the wind level is displayed;When setting is running: the window shows the wind speed alarm value.When the preset warning wind level is reached, it starts to flash and sound an alarm;
Precautions1.Before use, you must check whether the product (including plugs and flexible wires, etc.) is damaged. Pay attention to check whether the power supply is normal2.It is forbidden to install the product in a humid, dusty or flammable or corrosive environment.3.Disconnect the power supply before wiring.4.The plug and socket should be firmly connected to avoid looseness. Loose plugs and sockets can easily cause heat due to poor contact. Over time, it is likely to cause a fire.
