Product Description

BW-AH525C Series High-Precision CAN Attitude Heading Reference System built-in accelerometer, gyroscope and magnetometer



BW-AH525C uses high-quality and reliable MEMS devices, and uses temperature compensation and zero-drift correction algorithms to ensure measurement accuracy. It has a built-in accelerometer, gyroscope and magnetometer. At the same time, the sealing design and strict production process ensure that the product can still work reliably in harsh environments.

Q1: Accuracy definition of products

A: RMS accuracy, the accuracy of each product can be traced.Accuracy test report can be provided if required.


Q2: How to select suitable model?

A: Users should check the following points:

a. Single or dual axis?

b. Common protocol, Modbus or CAN?

c. Dynamic or static Application scenarios?

d. Horizontal or vertical installation?


Q3: How to purchase?

A: If you want sample, please purchase on BWSENSING online shop. We accept Paypal/TT/CC.If you purchase in bulk, it is recommended to consult the sales for the best price.


Q4: How long is the warranty period?

A: One year.


Q5: Fast troubleshooting for CAN products that cannot communicate

1. Firstly, the sensor's power supply voltage is determined according to the label of the sensor, and the output mode is wired according to the corresponding interface mode, and the corresponding protocol is used;

2. Use a multimeter to check the power supply voltage to ensure that the power supply is normal;

3. Configure the serial port parameters for communication, set the correct product address (normal protocol factory default 00, Modbus protocol factory default 01), select the correct baud rate (default 9600), open the computer device manager to confirm that the COM port number is selected correctly;
