BWM426 Cost-effective Dual-Axis Digital Output Inclinometer Technical Manual

Designed by Bewis Sensing Technology LLC, BWM426 is a cost-effective dual-axis digital output inclinometer with MEMS technology. It has a measuring range of ± 88° and a full-scale accuracy of 0.01° and a operating temperature of -40°C~+85°C The product has 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 digital mode. It has high long-term stability, small temperature drift, simple use and strong...

Cost-effective 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...
