WDS826FL Special dual axis tilt angle sensor for Product manual wind turbine tower shaking V1.1-20260708

Technical Characteristics ❖ Dual axis inclination measurement; ❖ Good low-frequency characteristics; ❖ Output options: RS485 / RS422 / RS232 (optional). WDS826FL is a dynamic tilt measurement product designed specifically for monitoring the shaking of wind turbine towers. It has excellent low-frequency response characteristics and can effectively capture slowly changing tilt signals, meeting the precise measurement needs in low-frequency dynamic scenarios. Before leaving the factory, the products undergo full temperature range calibration compensation and long-term stability testing to ensure...

The product includes Serial Communication Protocol and MODBUS RTU two protocols. The default configuration parameters of the protocol are as follows:_ Serial Communication Protocol1. Data frame format: Identifier Default parameters: address 0, baud rate 9600,1 start bit, 8 data, no parity, 1 stop bit. Valid setting address: 0~254 Identifier: fixed as 0x68; Data length: the length from data length to checksum (including checksum); Data field: according to the different content and length of the command word changes accordingly; Checksum: The sum of data length, address code, command word and data...

03 25Hz Auto output mode 04 35Hz Auto output mode 05 50Hz Auto output mode 06 100Hz Auto output mode before the sensor responds to the relative angle. Auto output mode: The sensor will automatically output X, Y angle and temperature after power on. If high frequency output is required, please set the baud rate to 115200. e.g.: 68 05 00 0C00 11 sensor reply command Data field (1byte)The No. in the data field e.g.: 68 05 00 8C 00 91 indicates the result of the sensor response 00: set successfully FF: set failed Set address command Data field(1byte) Note: All products have a common address: FF,...

Note, please read the description below carefully before using: 1> Because the MODBUS protocol stipulates that the time between two data frames should be at least 3.5 bytes (for example, at a baud rate of 9600, the time is 3.5x(1/9600)x11=0.004s). But in order to leave enough margin, please leave a time interval of 10ms between each data frame, please note that the automatic output of the product does not consider the T3.5 time. The host sends a command -- 10ms idle -- the slave replies to the command -- 10ms idle -- the host sends a command... 2> The MODBUS stipulates the broadcast address----0,...

Note: The data fields of the slave reply frame are 50H, 46H, 00H, 00H, 23H, 20H, 00H, 00H, 03H, 57H The X-axis represents the 1st to 4th bytes of the data field, the Y-axis represents the 5th to 8th bytes of the data field, and the lower bytes come first.The representation method of angle is dot notation, where one point corresponds to 0.0001 °, and 0.0001 x (dot offset) is the angle.If the measurement range is ± 10 °, the total number of points is 200000.So 0 corresponds to -10 °, 200000 corresponds to+10 °, and 100000 corresponds to 0 °. Taking the above data frame as an example: the process...

5.Set the sensor relative / absolute zero: MODBUS function code 06H Note: 0011H is the register address, which controls the sensor address. In the above example, the address of the sensor is changed to 0004H, and the last two bytes are the CRC checksum.

7. Set sensor serial port baud rate: (Factory default is 9600bps) The above example is to set the byte format to: one start bit+8 data bits without parity+1 stop bit Effective after re powering on. The factory default is a start bit+8 data bit parity+1 stop bit Note: 0009 is the register address, which controls the parity check bit of the sensor serial port. 0000H: One start bit+8 data bit parity checks+1 stop bit 0001 H: One start bit+8 data bits without checksum+1 stop bit 0002H: One start bit+8 data bits odd parity+1 stop bit

9.Set sensor output mode: (factory default 0HZ)

Note: 000EH is the register address, which controls the filter length of the sensor. In the above example, the sensor filter length is set to 32, and the last two bytes are the CRC checksum. Note: After setting the filtering length, it needs to be powered on again to take effect.
