BWK225S Low Cost Dual-Axis CAN Output Inclinometer Technical Manual

BWK 225S Low Cost Dual-Axis CAN Output Inclinometer Introduction Designed by Bewis Sensing Technology LLC, BWK225S is a low cost dual-axis CAN output Inclinometer, adopting the latest industrial level MEMS accelerometer. Its measuring range is ±90°, highest accuracy is 0.2°, working temperature is -40℃~+85℃, the product with a small size and low weight, can meet space-restricted application requirements. This product converts static gravity field changes into angle changes, It outputs horizontal angle values directly by digital, this product has the advantages of low cost, small temperature...

BWK 225S Low Cost Dual-Axis CAN Output Inclinometer Installation direction The correct installation method can avoid measurement error. The following points should be made when installing the sensor: First of all, to ensure that the sensor mounting surface and the measured surface completely close, the measured surface should be as horizontal as possible, can not have the angle shown in Figure A and Figure C, the correct installation is shown in Figure B and Figure D. A B uneven surface generates the angle D uneven surface generates the angle Secondly, the bottom cable of the sensor and the...

Protocol CAN includes 8 bytes. It will adds 0 to it when the date bytes is not enough. Sending the first byte 0x40 indicates a write command, returning the first byte 0x40 indicates that the write was successful. The ID is the CAN communication node number. Note: The fifth byte means 0x00 and 0x01. 0x00 indicates the setting is an absolute zero,0x01 indicates a relative zero. After setting the zero point, you need to enter the save command to set it successfully. (Default is absolute zero) Absolute zero: Based on the factory-calibrated zero point. Relative zero: Reference to the zero after...

4) Query relative/ absolute zero Note: The fifth byte mode is 0x00: answer mode, 0x01 : 5Hz Data Rate, 0x02: 1 0Hz Data Rate 0x03: 20Hz Data Rate, 0x04: 25Hz Data Rate, 0x05: 50Hz Data Rate, 0x06: 100Hz Data Rate(default) Note: The 5Hz Data Rate means that 5 times of data is automatically output every second. Sending other names should be done in the question and answer mode (automatic mode is to continuously output the current angle of the axis according to the specific frequency, and it is easier to see other commands in the answer mode. value).

8) Inclinometer sensor automatically outputs the angle When the sensor is set to automatic mode output, there will be an angle output after the sensor is powered on. Default is automatic mode. Note: The default standard CAN-ID is 0x580+05 and the maximum is not more than 7FF. Here we revise'580' in '0x580+05', 05 can be modified through the front nodes. After revise, the CAN-ID will become 0xXHXL+0x05 when re-powered on. For example, send the data: 605 40 71 10 00 01 23 00 00, the CAN-ID will become 123+5=128 when it is repowered on.

1 2) Set the extended address of CAN-ID We need to divide the address into two when setting the address of extended CAN-ID. First send high 16 address, then send the low 16 address. The CAN-ID address will change into new one (here the CAN-ID address we receive do not need to add the nodes) after being re-powered on. The maximum can not be more than 7FFFFFF. The default is 0x18fa0216. I Set high 16 extended address of CAN-ID Note: Low 16 address can not surpass FFFF. For example, send the data respectively as follows, 605 40 72 10 00 01 23 00 00 and 605 40 73 10 00 45 67 00 00. CAN-ID will...
