AKP342 VIBRATION SENSOR FOR FAN MONITORING AKP342 is a high-precision, low-noise three-axis Vibration sensor specially for monitoring wind turbines. All products have been calibrated and compensated in the whole temperature range and tested for long-term stability for two weeks before leaving the factory to ensure that the best performance indicators are maintained under different working conditions and long-term test cycles. The product integrates the FFT function, which can measure the static 0HZ or 0.1 ~ 10Hz vibration, estimate the object vibration data by algorithm, and obtain the 60-second...

Please install the tilt sensor according to the correct method. Incorrect installation will lead to measurement errors. Pay special attention to one "surface" and two "lines": 1) The mounting surface of the sensor and the surface to be measured must be fixed tightly, smoothly and stably. If the mounting surface is uneven, it is easy to cause the error of the included angle measured by the sensor. 2) The axis of the sensor must be parallel to the axis to be measured, and the two axes should not form an angle as far as possible. MOUNTING SURFACE

AKP342 VIBRATION SENSOR FOR FAN MONITORING ▶ INSTALLATION DIRECTION During installation, keep the mounting surface of the sensor parallel to the surface of the target to be measured, so as to reduce the influence of dynamic and acceleration on the sensor. This product can be installed horizontally or vertically. Please refer to the following schematic diagram for the installation method: ▶ WORKING PRINCIPLE OF VIBRATION It adopts imported core control unit and uses the principle of capacitive miniature pendulum. According to the gravity principle of the earth, the gravity of the earth can generate...

The product includes two protocols, namely, the 68 protocol and the MODBUS RTU protocol. The default configuration parameters of the protocols are as follows: MB protocol format description

Default communication parameters: address 0, baud rate 9600, 1start bit, 8-bit data, no check, 1stop bit Valid setting address: 0 ~ 254 Identifier: fixed as 0x68; Data length: length from data length to checksum (including checksum); Data field: change according to different content and length of command word; Checksum: Sum of data length, address code, command word and data field, without considering carry, i.e. Sum & 0xFF.

Note that please read the following items carefully before use: 1 > To ensure normal communication, please leave a time interval of 10ms between two data frames. Master sends command --10 ms idle -- Slave replies command --10 ms idle -- Master sends command 2 > The protocol specifies the broadcast address -- 255. The sensor can also accept the broadcast address content, but will not reply (except for the function of reading the address code). Therefore, the broadcast address 255 can be used for the following purposes for reference only. 1 .Set the address of all the tilt sensors of this model...

MODBUS uses RTU mode, 'big-Endian' indicates address and data items, takes CRC16 to verify data, supports 0x03 to read holding register and 0x06 to write single register. 1. Data frame format: Default communication parameters: address 1, baud rate 9600, 1start bit, 8-bit data, even parity, 1stop bit; CRC check: the range is the check of all bytes before the CRC field, and 16-bit CRC check is used.

Note that please read the following items carefully before use: 1 > Because the MODBUS protocol stipulates that the time between two data frames should be at least more than 3.5 bytes (for example, under the baud rate of 9600, the time is 3.5 x (1/9600) x 11 = 0.004s). However, in order to leave enough margin, please leave a time interval of 10 ms between each data frame. Please note that the automatic output of the product does not consider the T3.5 time. Master sends command -- 10 ms idle -- Slave replies command -- 10 ms idle -- Master sends command 2 > The MODBUS protocol specifies the relevant...

Commands must be sent twice in a row to be valid The above example is to format the byte as: one start bit + 8 data bits without parity + 1stop bit Valid after power up again. Factory default is one start bit + 8 data bits even parity + 1stop bit Note: 0009 is the register address that controls the sensor serial parity bit. 0000H: one start bit + 8 data bits even parity + 1stop bit 0001H: one start bit + 8 data bits without check + 1stop bit 0002H: one start bit + 8 data bits odd parity + 1stop bit

6. Set the sensor output mode: (factory default 0 HZ) Note: 0020H is the register address, which controls the automatic output data item. In the above example, the sensor automatic output data item is set to all data output, and the last two bytes are the CRC checksum.
