GKP3 Low Frequency Vibration Sensor Product Manual

[Vj Technical Highlights ❖ Triaxial MEMS vibration sensor; The GKP3 is a triaxial vibration sensor independently developed for low-frequency vibration monitoring, featuring high precision and low noise. Each product undergoes calibration and compensation across the entire temperature range and approximately 336 hours of long-term stability testing before leaving the factory, ensuring stable performance under diverse operating conditions and continuous testing cycles. The sensor supports static vibration measurement in the 0Hz or 0.1-100Hz frequency bands and integrates two output protocols, including...

Product Dimensions Housing dimensions: L93×W70×H41mm Mounting dimensions: L71×W56×H8mm Recommended screws: 4 M6 screws Installation Orientation During installation, the sensor mounting surface should be kept parallel to the surface of the target object to minimize the impact of dynamics and acceleration on the sensor. This product can be installed horizontally or vertically; please refer to the diagram below for installation instructions:

Male connector Signal ground Male connector Signal ground Interface connection instructions- 1. Select cables that conform to RS-485/RS-232 standards, ensuring the cable quality and performance meet the requirements. Twisted-pair cable is recommended due to its better anti-interference capability. 2. At both terminal devices in the RS-485/RS-232 communication network, terminating resistors (typically 120 ohms) need to be connected to eliminate signal reflections. Avoid connecting terminating resistors on intermediate devices to prevent signal interference. 3. To ensure system stability and security,...

Please install the tilt sensor correctly. Incorrect installation will lead to measurement errors. Pay special attention to two key aspects: 1) The sensor mounting surface must be tightly, flat, and stable against the surface being measured. Uneven mounting surfaces can easily cause angular errors in the sensor measurement. 2) The sensor axis and the axis being measured must be parallel, and the two axes should ideally not form an angle. Mounting surface [vf Communication Protocol The product supports two protocols: serial communication and MODBUS RTU. The default configuration parameters for...

Default output data field format description Serial communication protocol format description The data field format uses big-endian mode, which is parsed as a data value multiplied by a coefficient. For example, the X-axis acceleration FF FF 4C 58 is -45992, and the result is -45992*0.000001 =-0.045992g. The Y-axis acceleration 00 01 86 A0 is 100000*0.000001=0.1g.

This output item is related to the automatic output mode command. The corresponding bit position determines the output, with lower bits indicating earlier data content. The automatic output item is 07F7H, meaning all content is output in the following order from left to right: Reservation Count | Status | Acceleration | Temperature.____ [vf Serial communication protocol l/Data Frame Format: Default communication parameters: Address 0, Baud rate 9600, 1 start bit, 8 data bits, no Valid address range: 0~254 Data length: Length from data length to checksum (including checksum); Data field: Varies...

2. Command word parsing

MODBUS uses RTU mode, with 'big-Endian' indicating address and data items, employs CRC16 checksum for data, supports reading holding registers at 0x03, and writing single registers at 0x06. 1. Data Frame Format: 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: Checksum of all bytes before the CRC field, using 16-bit CRC checksum. Please note that you should read the following items carefully before use: l>The MODBUS protocol stipulates that there should be at least 3.5 bytes of time between...

3. Set the sensor address: (The sensor address is set to 1 by default at the factory)

Note: 0020H is the register address, which controls the automatic output data items. In the example above, the sensor's automatic output data items are set to all data outputs, and the last two bytes are the CRC checksum.

8. Set the sensor's relative/absolute zero point: (Modbus function code 06H) Note: 0010 is the register address, which controls the sensor's current angle to be zero degrees, and the accelerations X, Y, Z to be 0, 0,1g. If it is non-zero (as in the example above, it is written to 00FFH), the output is a relative zero point. Conversely, if it is zero (by changing the 5th and 6th bytes to 00H), it is an absolute zero point. The last two bytes are the CRC checksum.
