BWN428 Cost-effective Dual-Axis Current Output Inclinometer Technical Manual

Cost-effective Dual-Axis Current Output Inclinometer Designed by Wuxi Bewis Sensing Technology LLC, BWN428 is a cost-effective dual-axis current output inclinometer with MEMS technology. It has a measuring range of ±30° and the highest accuracy of 0.02° and a operating temperature of -40°C~+85°C. 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 current mode. It has high...

BWN 428 Cost-effective Dual-Axis Current Output Inclinometer 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. Secondly, the bottom cable of the sensor and the axis of the measured object shouldn't generate the angle shown in E. When installing, the...
