BWS4800 High Precision Dual-Axis Current Output Inclinometer Technical Manual

High Precision Dual-Axis Current Output Inclinometer Introduction Designed by Bewis Sensing Technology LLC, BWS4800 is a high precision dual-axis current output inclinometer with MEMS technology. It has a measuring range of ± 90° and a full scale accuracy of 0.008°. It is a highly accurate product in the industry for now. 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 current roll angle and pitch angle...

High Precision Dual-Axis Current 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. B uneven surface generates the angle D uneven surface generates the angle Secondly, the bottom cable of the sensor and the...
