BWN426 Digital Dual-Axis Inclinometer Technical Manual

Designed by Wuxi Bewis Sensing Technology LLC, BWN426 is a cost-effective dual-axis inclinometer with MEMS technology and digital output. It has a measuring range of ±30° and a full-scale accuracy of 0.02° and a operating temperature of -40°C~+85°C. The product uses a high-accuracy MEMS accelerometer and a high-resolution differential digital-to-analog converter with built-in 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...

Digital Dual-Axis 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 the measured object...
