BWN427 Cost-effective Dual-Axis Digital Output with Modbus Inclinometer Technical Manual

Cost-effective Dual-Axis Digital Output with Modbus Inclinometer Introduction Designed by Bewis Sensing Technology LLC, BWN427 is a cost-effective dual-axis digital output with Modbus inclinometer with MEMS technology. It has a measuring range of ±30° and a full-scale accuracy of 0.02° and a operating temperature of -40℃~+85℃. 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...

Cost-effective Dual-Axis Digital Output with Modbus 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...
