BWL326S Low Cost Dual-Axis Digital Output Inclinometer Technical Manual

Low Cost Dual-Axis Digital Output Inclinometer Introduction Designed by Bewis Sensing Technology LLC, BWL326S is a low cost dual-axis digital output inclinometer, adopting the latest industrial level MEMS accelerometer. Its measuring range is ±90°, highest accuracy is 0.1°, working temperature is -40℃~+85℃, the product with a small size and low weight, can meet space-restricted application requirements. This horizontal angle values cost, static directly changes this small temperature drift, simple to use, and strong resistance to external disturbances. It is an ideal option for attitude measurement...

Low Cost Dual-Axis Digital 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 of...

Low Cost Dual-Axis Digital Output Inclinometer Debug software Users can directly download serial assistant on official website (Supports-Download). You can also use more convenient and intuitive PC software. BWL326S supporting serial debugging software can be connected to the inclinometer on the computer for angle display. The software debugging interface is as shown in the figure below. Using the debug software, it can conveniently display the current X-direction tilt angle, and you can also modify and set other parameters by yourself. Software use steps: ① Correctly connect the inclinometer...
