GKG3 MEMS Digital Vibration sensor Product Manuel V2.4-20260706

Technical Highlights ❖ RS232/485/TTL signal output optional; ❖ Vibration: 10~2000Hz, 10g; ❖ Shock: 100g@11ms, triaxial (half-sine wave); ❖ High stability and strong environmental performance: shock resistant, vibration resistant, and wide temperature range. Product Introduction The GKG3 triaxial Vibration sensor is a widely used multi-axis Vibration sensor series product independently developed by RUICOM Technology, suitable for various engineering scenarios such as vibration detection and shock testing. This series supports digital interface output, with selectable RS232, RS485, or TTL communication...

Vibration parameter index - The vibration frequency, velocity, and amplitude of this product are derived from data analysis. The frequency is the main frequency of the current object's vibration, the velocity is the vibration speed, and the amplitude is the vibration amplitude value of the object. Due to the irregularity of the object's vibration, the data is for reference only._

The default configuration parameters for the protocols are as follows: Automatic Output Data Items This output item is related to the automatic output mode command. The corresponding bit position determines the output; the lower the bit, the earlier the data appears. That is, all

- www.ruicomtech.com -output content is ordered from left to right as: Acceleration|Frequency|Velocity|Amplitude|Temperature. For E.g: Serial communication protocol: Automatic output item is 1011H, then the automatic output data is: Acceleration|Frequency|Amplitude; Modbus protocol: Automatic output item is 9001H, then the automatic output data is: Acceleration|Amplitude|Temperature. The table below describes the relationship between output rate, data content, and baud rate. Please calculate and set the parameters appropriately based on the parameters. Automatic data output is invalid; only Automatic...

1. Data Frame Format: Default communication parameters: Address 0, baud rate 9600, 1 start bit, 8 data bits, no parity, 1 stop bit; Valid address range: 0~254; Data length: Length from data length to checksum (including checksum); Data field: Varies depending on the content and length of the command word; Checksum: The sum of data length, address code, command word, and data field, ignoring carry, i.e., Sum & 0xFF. 2. Command word parsing Read X-axis acceleration command Read Y-axis acceleration command Read Z-axis acceleration command Simultaneously read acceleration Sensor response Data Field...

1. If multiple sensors are connected to a single bus, such as RS485, each sensor must be assigned a different address to control and respond to acceleration separately. 2. If the address is successfully changed, all subsequent command and response data packets must use the new address code to be effective; otherwise, the sensor will not respond to commands. Note: All products share a common address:FF Reset the address to 00 using a general address. Sensor response command Data Field (1 byte) E.g: 68 05 00 8F 00 94 The number in the data field represents the sensor response result: 00 Success...

Send the setting address command -- wait for the slave device to send a success command -- (no other commands should appear) Send the setting address command again -- wait for the slave device to send a success command -- Modification successful Default communication parameters: Address 1, baud rate 9600, 1 start bit, 8 data bits, even parity, 1 stop bit; Valid address range: 1~247; CRC checksum: The range is the checksum of all bytes before the CRC field, using 16-bit CRC checksum.

Commands must be sent twice consecutively to be effective.

The above E.g sets the byte format to: one start bit + 8 data bits, no parity, + 1 stop bit. This setting takes effect after a power cycle. The factory default is one start bit + 8 data bits, even parity, + 1 stop bit. Note: 0009 is the register address; this register controls the sensor communication character format. 0000H: One start bit + 8 data bits, even parity, + 1 stop bit 0001H: One start bit + 8 data bits, no parity, + 1 stop bit

8. Set the sensor output mode: (Factory default: 0Hz) Note: 0000H is the register address, which controls the sensor's automatic data output. In the E.g above, the sensor's output is set to 9111H, and the last two bytes are the CRC checksum.

10. Read sensor output data items automatically: Note: 0014H is the register address, which controls the sensor bandwidth. In the E.g above, the sensor bandwidth is set to 500Hz, and the last two bytes are the CRC checksum.
