BWN425 Cost-effective Dual-Axis CAN Output Inclinometer Technical Manual

Cost-effective Dual-Axis CAN Output Inclinometer Introduction Designed by Bewis Sensing Technology LLC, BWN425 is a cost-effective dual-axis CAN output inclinometer with MEMS technology. It has a measuring range of ± 88° and a full-scale accuracy of 0.05° and a operating temperature of -40℃~+85℃. The product uses automatic compensation and filtering algorithms to reduce errors caused by environmental changes. It measures the change of static gravitational field and converts it into angle change. The change directly outputs the horizontal angle value through digital mode. It has high long-term...

Cost-effective 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 axis...

BWN 425 Cost-effective Dual-Axis CAN Output Inclinometer 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, and returning the first byte 0x40 indicates that the write was successful. The ID is the CAN communication node number. 1)Modify the nodes (ID=0x01~0x7F),default ID=0x05 CAN-ID byte^^ second third fourth fifth sixth seventh eighth Note: If the controller send CAN-ID=0x600+0x05(default), send data:40 10 10 00 10 00 00 00 If the sensor return CAN-ID=0x580+0x10, return data:40 10 10 00 10 00 00 00 The CAN-ID...

4) Query relative/ absolute zero CAN-ID bytefirSt second third fourth fifth sixth seventh eighth Note: the fifth byte means 0x00 and 0x01. 0x00 indicates an absolute zero and 0x01 indicates a relative zero.

8) Inclinometer sensor automatically outputs the angle When the sensor is set to automatic mode output, the sensor automatically outputs the angle according to a certain frequency after the sensor is powered on. CAN-ID bytef'rSt second third fourth fifth sixth seventh eighth send response 0x580 + 0x05 Xsign XH XL XL Ysign YH YL YL Note: The output angle format is the same as the answer mode read X angles and Y angles. CAN-ID bytef'rst second third fourth fifth sixth seventh eighth response Note: XX means 00 and 01. 00 means the standard ID type (11 bits) and 01 means extended ID type (27 bits)....

11) 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 0x1FFFFFFF. The default is 0x18fa0216.
