Product Description

BWM425S Cost-Effective MEMS High-Precision CAN Bus Dual Axis Inclinometer 



BWM425S is a cost-effective dual axis inclination sensor with can output, the highest accuracy is 0.02 °, and the working temperature is - 40 ℃ - + 85 ℃. The product has built-in automatic compensation and filtering algorithm to eliminate the error caused by environmental change to the greatest extent. The horizontal inclination value is directly output through digital mode, which has high stability, simple use, small temperature drift and strong anti-interference ability. It is an excellent choice for inclination measurement in structural monitoring, surveying and mapping, medical devices and other industries!

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. Commom 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.
